			SENDMAIL RELEASE NOTES


This listing shows the version of the sendmail binary, the version
of the sendmail configuration files, the date of release, and a
summary of the changes in that release.

8.15.2/8.15.2	2015/07/03
	If FEATURE(`nopercenthack') is used then some bogus input triggered
		a recursion which was caught and logged as
		SYSERR: rewrite: excessive recursion (max 50) ...
		Fix based on patch from Ondrej Holas.
	DHParameters now by default uses an included 2048 bit prime.
		The value 'none' previously caused a log entry claiming
		there was an error "cannot read or set DH parameters".
		Also note that this option applies to the server side only.
	The U= mailer field didn't accept group names containing hyphens,
		underbars, or periods.  Based on patch from David Gwynne
		of the University of Queensland.
	CONFIG: Allow connections from IPv6:0:0:0:0:0:0:0:1 to relay again.
		Patch from Lars-Johan Liman of Netnod Internet Exchange.
	CONFIG: New option UseCompressedIPv6Addresses to select between
		compressed and uncompressed IPv6 addresses.  The default
		value depends on the compile-time option IPV6_FULL:
		For 1 the default is False, for 0 it is True, thus
		preserving the current behaviour.  Based on patch from
		John Beck of Oracle.
	CONFIG: Account for IPv6 localhost addresses in
		FEATURE(`block_bad_helo').  Suggested by Andrey Chernov
		from FreeBSD and Robert Scheck from the Fedora Project.
	CONFIG: Account for IPv6 localhost addresses in check_mail ruleset.
	LIBMILTER: Deal with more invalid protocol data to avoid potential
		crashes.  Problem noted by Dimitri Kirchner.
	LIBMILTER: Allow a milter to specify an empty macro list ("", not
		NULL) in smfi_setsymlist() so no macro is sent for the
		selected stage.
	MAKEMAP: A change to check TrustedUser in fewer cases which was
		made in 2013 caused a potential regression when makemap
		was run as root (which should not be done anyway).
	Note: sendmail often contains options "For Future Releases"
		(prefix _FFR_) which might be enabled in a subsequent
		version or might simply be removed as they turned out not
		to be really useful.  These features are usually not
		documented but if they are, then the required (FFR)
		options are listed in
		- doc/op/op.* for rulesets and macros,
		- cf/README for mc/cf options.

8.15.1/8.15.1	2014/12/06
	SECURITY: Properly set the close-on-exec flag for file descriptors
		(except stdin, stdout, and stderr) before executing mailers.
	If header rewriting fails due to a temporary map lookup failure,
		queue the mail for later retry instead of sending it
		without rewriting the header.  Note: this is done
		while the mail is being sent and hence the transaction
		is aborted, which only works for SMTP/LMTP mailers
		hence the handling of temporary map failures is
		suppressed for other mailers. SMTP/LMTP servers may
		complain about aborted transactions when this problem
		occurs.
		See also "DNS Lookups" in sendmail/TUNING.
	Incompatible Change: Use uncompressed IPv6 addresses by default,
		i.e., they will not contain "::".  For example,
		instead of ::1 it will be 0:0:0:0:0:0:0:1.  This
		permits a zero subnet to have a more specific match,
		such as different map entries for IPv6:0:0 vs IPv6:0.
		This change requires that configuration data
		(including maps, files, classes, custom ruleset,
		etc) must use the same format, so make certain such
		configuration data is updated before using 8.15.
		As a very simple check search for patterns like
		'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. If necessary,
		the prior format can be retained by compiling with:
		APPENDDEF(`conf_sendmail_ENVDEF', `-DIPV6_FULL=0')
		in your devtools/Site/site.config.m4 file.
	If debugging is turned on (-d0.14) also print the OpenSSL
		versions, both build time and run time
		(provided STARTTLS is compiled in).
	If a connection to the MTA is dropped by the client before its
		hostname can be validated, treat it as "may be forged",
		so that the unvalidated hostname is not passed to a
		milter in xxfi_connect().
	Add a timeout for communication with socket map servers
		which can be specified using the -d option.
	Add a compile time option HESIOD_ALLOW_NUMERIC_LOGIN to allow
		numeric logins even if HESIOD is enabled.
	The new option CertFingerprintAlgorithm specifies the finger-
		print algorithm (digest) to use for the presented cert.
		If the option is not set, md5 is used and the macro
		{cert_md5} contains the cert fingerprint.
		However, if the option is set, the specified algorithm
		(e.g., sha1) is used and the macro {cert_fp} contains
		the cert fingerprint.
		That is, as long as the option is not set, the behaviour
		does not change, but otherwise, {cert_md5} is superseded
		by {cert_fp} even if you set CertFingerprintAlgorithm
		to md5.
	The options ServerSSLOptions and ClientSSLOptions can be used
		to set SSL options for the server and client side
		respectively. See SSL_CTX_set_options(3) for a list.
		Note: this change turns on SSL_OP_NO_SSLv2 and
		SSL_OP_NO_TICKET for the client. See doc/op/op.me
		for details.
	The option CipherList sets the list of ciphers for STARTTLS.
		See ciphers(1) for possible values.
	Do not log "STARTTLS: internal error: tls_verify_cb: ssl == NULL"
		if a CRLFfile is in use (and LogLevel is 14 or higher.)
	Store a more specific TLS protocol version in ${tls_version}
		instead of a generic one, e.g., TLSv1 instead of
		TLSv1/SSLv3.
	Properly set {client_port} value on little endian machines.
		Patch from Kelsey Cummings of Sonic.net.
	Per RFC 3848, indicate in the Received: header whether SSL or
		SMTP AUTH was negotiated by setting the protocol clause
		to ESMTPS, ESMTPA, or ESMTPSA instead of ESMTP.
	If the 'C' flag is listed as TLSSrvOptions the requirement for the
		TLS server to have a cert is removed.  This only works
		under very specific circumstances and should only be used
		if the consequences are understood, e.g., clients
		may not work with a server using this.
	The options ClientCertFile, ClientKeyFile, ServerCertFile, and
		ServerKeyFile can take a second file name, which must be
		separated from the first with a comma (note: do not use
		any spaces) to set up a second cert/key pair. This can
		be used to have certs of different types, e.g., RSA
		and DSA.
	A new map type "arpa" is available to reverse an IP (IPv4 or IPv6)
		address. It returns the string for the PTR lookup, but
		without trailing {ip6,in-addr}.arpa.
	New operation mode  'C' just checks the configuration file, e.g.,
		sendmail -C new.cf -bC
		will perform a basic syntax/consistency check of new.cf.
	The mailer flag 'I' is deprecated and will be removed in a
		future version.
	Allow local (not just TCP) socket connections to the server, e.g.,
		O DaemonPortOptions=Family=local, Addr=/var/mta/server.sock
		can be used.
	If the new option MaxQueueAge is set to a value greater than zero,
		entries in the queue will be retried during a queue run
		only if the individual retry time has been reached which
		is doubled for each attempt.  The maximum retry time is
		limited by the specified value.
	New DontBlameSendmail option GroupReadableDefaultAuthInfoFile
		to relax requirement for DefaultAuthInfo file.
	Reset timeout after receiving a message to appropriate value if
		STARTTLS is in use.  Based on patch by Kelsey Cummings
		of Sonic.net.
	Report correct error messages from the LDAP library for a range of
		small negative return values covering those used by OpenLDAP.
	Fix compilation with Berkeley DB 5.0 and 6.0.  Patch from
		Allan E Johannesen of Worcester Polytechnic Institute.
	CONFIG: FEATURE(`nopercenthack') takes one parameter: reject or
		nospecial which describes whether to disallow "%" in the
		local part of an address.
	DEVTOOLS: Fix regression in auto-detection of libraries when only
		shared libraries are available.  Problem reported by
		Bryan Costales.
	LIBMILTER: Mark communication socket as close-on-exec in case
		a user's filter starts other applications.
		Based on patch from Paul Howarth.
	Portability:
		SunOS 5.12 has changed the API for sigwait(2) to conform
		with XPG7.  Based on patch from Roger Faulkner of Oracle.
	Deleted Files:
		libsm/path.c

8.14.9/8.14.9	2014/05/21
	SECURITY: Properly set the close-on-exec flag for file descriptors
		(except stdin, stdout, and stderr) before executing mailers.
	Fix a misformed comment in conf.c: "/*" within comment
		which may cause a compilation error on some systems.
		Problem reported by John Beck of Oracle.
	DEVTOOLS: Fix regression in auto-detection of libraries when only
		shared libraries are available.  Problem reported by
		Bryan Costales.

8.14.8/8.14.8	2014/01/26
	Properly initialize all OpenSSL algorithms for versions before
		OpenSSL 0.9.8o. Without this SHA2 algorithms may not
		work properly, causing for example failures for certs
		that use sha256WithRSAEncryption as signature algorithm.
	When looking up hostnames, ensure only to return those records
		for the requested family (AF_INET or AF_INET6).
		On system that have NEEDSGETIPNODE and NETINET6
		this may have failed and cause delivery problems.
		Problem noted by Kees Cook.
	A new mailer flag '!' is available to suppress an MH hack
		that drops an explicit From: header if it is the
		same as what sendmail would generate.
	Add an FFR (for future release) to use uncompressed IPv6 addresses,
		i.e., they will not contain "::".  For example, instead
		of ::1 it will be 0:0:0:0:0:0:0:1.  This means that
		configuration data (including maps, files, classes,
		custom ruleset, etc) have to use the same format.
		This will be turned on in 8.15.  It can be enabled in 8.14
		by compiling with:
		APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_IPV6_FULL')
		in your devtools/Site/site.config.m4 file.
	Add an additional case for the WorkAroundBrokenAAAA check when
		dealing with broken nameservers by ignoring SERVFAIL
		errors returned on T_AAAA (IPv6) lookups at delivery time.
		Problem noted by Pavel Timofeev of OCS.
	If available, pass LOGIN_SETCPUMASK and LOGIN_SETLOGINCLASS to
		setusercontext() on deliveries as a different user.
		Patch from Edward Tomasz Napierala from FreeBSD.
	Avoid compiler warnings from a change in Cyrus-SASL 2.1.25.
		Patch from Hajimu UMEMOTO from FreeBSD.
	Add support for DHParameters 2048-bit primes.
	CONFIG: Accept IPv6 literals when evaluating the HELO/EHLO argument
		in FEATURE(`block_bad_helo').  Suggested by Andrey Chernov.
	LIBSMDB: Add a missing check for malloc() in libsmdb/smndbm.c.
		Patch from Bill Parker.
	LIBSMDB: Fix minor memory leaks in libsmdb/ if allocations
		fail.  Patch from John Beck of Oracle.
	Portability:
		Add support for Darwin 12.x and 13.x (Mac OS X 10.8 and 10.9).
		On Linux use socklen_t as the type for the 3rd argument
		for getsockname/getpeername if the glibc version is at
		least 2.1.
	Added Files:
		devtools/OS/Darwin.12.x
		devtools/OS/Darwin.13.x

8.14.7/8.14.7	2013/04/21
	Drop support for IPv4-mapped IPv6 addresses to prevent the MTA
		from using a mapped address over a legitimate IPv6 address
		and to enforce the proper semantics over the IPv6
		connection.  Problem noted by Ulrich Sporlein.
	Fix a regression introduced in 8.14.6: the wrong list of
		macros was sent to a milter in the EHLO stage.
		Problem found by Fabrice Bellet, reported via RedHat
		(Jaroslav Skarvada).
	Fix handling of ORCPT parameter for DSNs: xtext decoding
		was not performed and a wrong syntax check was applied
		to the "addr-type" field.  Problem noted by Dan Lukes
		of Obludarium.
	Fix handling of NUL characters in the MIME conversion functions
		so that message bodies containing them will be sent
		on properly. Note: this usually also affects mails
		that are not converted as those functions are used
		for other purposes too.  Problem noted by Elchonon
		Edelson of Lockheed Martin.
	Do not perform "duplicate" elimination of recipients if they
		resolve to the error mailer using a temporary failure
		(4xy) via ruleset 0.  Problem noted by Akira Takahashi
		of IIJ.
	CONTRIB: Updated version of etrn.pl script from John Beck
		of Oracle.
	Portability:
		Unlike gcc, clang doesn't apply full prototypes to K&R
		definitions.

8.14.6/8.14.6	2012/12/23
	Fix a regression introduced in 8.14.5: if a server offers
		two AUTH lines, the MTA would not read them after
		STARTTLS has been used and hence SMTP AUTH for
		the client side would fail.  Problem noted by Lena.
	Do not cache hostnames internally in a non case sensitive way
		as that may cause addresses to change from lower case
		to upper case or vice versa. These header modifications
		can cause problems with milters that rely on receiving
		headers in the same way as they are being sent out such
		as a DKIM signing milter.
	If MaxQueueChildren is set then it was possible that new queue
		runners could not be started anymore because an
		internal counter was subject to a race condition.
	If a milter decreases the timeout it waits for a communication
		with the MTA, the MTA might experience a write() timeout.
		In some situations, the resulting error might have been
		ignored.  Problem noted by Werner Wiethege.
		Note: decreasing the communication timeout in a milter
		should not be done without considering the potential
		problems.
	smfi_setsymlist() now properly sets the list of macros for
		the milter which invoked it, instead of a global
		list for all milters.  Problem reported by
		David Shrimpton of the University of Queensland.
	If Timeout.resolver.retrans is set to a value larger than 20,
		then resolver.retry was temporarily set to 0 for
		gethostbyaddr() lookups. Now it is set to 1 instead.
		Patch from Peter.
	If sendmail could not lock the statistics file due to a system
		error, and sendmail later sends a DSN for a mail that
		triggered such an error, then sendmail tried to access
		memory that was freed before (causing a crash on some
		systems).  Problem reported by Ryan Stone.
	Do not log negative values for size= nor pri= to avoid confusing
		log parsers, instead limit the values to LONG_MAX.
	Account for an API change in newer versions of Cyrus-SASL.
		Patch from Hajimu UMEMOTO from FreeBSD.
	Do not try to resolve link-local addresses for IPv4 (just as it
		is done for IPv6).  Patch from John Beck of Oracle.
	Improve logging of client and server STARTTLS connection failures
		that may be due to incompatible cipher lists by including
		the reason for the failure in a single log line.  Suggested
		by James Carey of Boeing.
	Portability:
		Add support for Darwin 11.x (Mac OS X 10.7).
		Add support for SunOS 5.12 (aka Solaris 12). Patch from
		John Beck of Oracle.
	Added Files:
		devtools/OS/Darwin.11.x
		devtools/OS/SunOS.5.12

8.14.5/8.14.5	2011/05/17
	Do not cache SMTP extensions across connections as the cache
		is based on hostname which may not be a unique identifier
		for a server, i.e., different machines may have the
		same hostname but provide different SMTP extensions.
		Problem noted by Jim Hermann.
	Avoid an out-of-bounds access in case a resolver reply for a DNS
		map lookup returns a size larger than 1K.  Based on a
		patch from Dr. Werner Fink of SuSE.
	If a job is aborted using the interrupt signal (e.g., control-C from
		the keyboard), perform minimal cleanup to avoid invoking
		functions that are not signal-safe. Note: in previous
		versions the mail might have been queued up already
		and would be delivered subsequently, now an interrupt
		will always remove the queue files and thus prevent
		delivery.
	Per RFC 6176, when operating as a TLS client, do not offer SSLv2.
	Since TLS session resumption is never used as a client, disable
		use of RFC 4507-style session tickets.
	Work around gcc4 versions which reverse 25 years of history and
		no longer align char buffers on the stack, breaking calls
		to resolver functions on strict alignment platforms.
		Found by Stuart Henderson of OpenBSD.
	Read at most two AUTH lines from a server greeting (up to two
		lines are read because servers may use "AUTH mechs" and
		"AUTH=mechs"). Otherwise a malicious server may exhaust
		the memory of the client.  Bug report by Nils of MWR
		InfoSecurity.
	Avoid triggering an assertion in the OpenLDAP code when the
		connection to an LDAP server is lost while making a query.
		Problem noted and patch provided by Andy Fiddaman.
	If ConnectOnlyTo is set and sendmail is compiled with NETINET6
		it would try to use an IPv6 address if an IPv4 (or
		unparseable) address is specified.
	If SASLv2 is used, make sure that the macro {auth_authen} is
		stored in xtext format to avoid problems with parsing
		it.  Problem noted by Christophe Wolfhugel.
	CONFIG: FEATURE(`ldap_routing') in 8.14.4 tried to add a missing
		-T<TMPF> that is required, but failed for some cases
		that did not use LDAP.  This change has been undone
		until a better solution can be implemented.  Problem
		found by Andy Fiddaman.
	CONFIG: Add cf/ostype/solaris11.m4 for Solaris11 support.
		Contributed by Casper Dik of Oracle.
	CONTRIB: qtool.pl: Deal with H entries that do not have a
		letter between the question marks.  Patch from
		Stefan Christensen.
	DOC: Use a better description for the -i option in sendmail.
		Patch from Mitchell Berger.
	Portability:
		Add support for Darwin 10.x (Mac OS X 10.6).
		Enable HAVE_NANOSLEEP for FreeBSD 3 and later.  Patch
		from John Marshall.
		Enable HAVE_NANOSLEEP for OpenBSD 4.3 and later.
		Use new directory "/system/volatile" for PidFile on
		Solaris 11.  Patch from Casper Dik of Oracle.
		Fix compilation on Solaris 11 (and maybe some other
		OSs) when using OpenSSL 1.0.  Based on patch from
		Jan Pechanec of Oracle.
		Set SOCKADDR_LEN_T and SOCKOPT_LEN_T to socklen_t
		for Solaris 11.  Patch from Roger Faulkner of Oracle.
	New Files:
		cf/ostype/solaris11.m4

8.14.4/8.14.4	2009/12/30
	SECURITY: Handle bogus certificates containing NUL characters
		in CNs by placing a string indicating a bad certificate
		in the {cn_subject} or {cn_issuer} macro.  Patch inspired
		by Matthias Andree's changes for fetchmail.
	During the generation of a queue identifier an integer overflow
		could occur which might result in bogus characters
		being used.  Based on patch from John Vannoy of
		Pepperdine University.
	The value of headers, e.g., Precedence, Content-Type, et.al.,
		was not processed correctly.  Patch from Per Hedeland.
	Between 8.11.7 and 8.12.0 the length limitation on a return
		path was erroneously reduced from MAXNAME (256) to
		MAXSHORTSTR (203).  Patch from John Gardiner Myers
		of Proofpoint; the problem was also noted by Steve
		Hubert of University of Washington.
	Prevent a crash when a hostname lookup returns a seemingly
		valid result which contains a NULL pointer (this seems
		to be happening on some Linux versions).
	The process title was missing the current load average when
		the MTA was delaying connections due to DelayLA.
		Patch from Dick St.Peters of NetHeaven.
	Do not reset the number of queue entries in shared memory if
		only some of them are processed.
	Fix overflow of an internal array when parsing some replies
		from a milter.  Problem found by Scott Rotondo
		of Sun Microsystems.
	If STARTTLS is turned off in the server (via M=S) then it
		would not be initialized for use in the client either.
		Patch from Kazuteru Okahashi of IIJ.
	If a Diffie-Hellman cipher is selected for STARTTLS, the
		handshake could fail with some TLS implementations
		because the prime used by the server is not long enough.
		Note: the initialization of the DSA/DH parameters for
		the server can take a significant amount of time on slow
		machines. This can be turned off by setting DHParameters
		to none or a file (see doc/op/op.me).  Patch from
		Petr Lampa of the Brno University of Technology.
	Fix handling of `b' modifier for DaemonPortOptions on little
		endian machines for loopback address.  Patch from
		John Beck of Sun Microsystems.
	Fix a potential memory leak in libsmdb/smdb1.c found by parfait.
		Based on patch from Jonathan Gray of OpenBSD.
	If a milter sets the reply code to "421" during the transfer
		of the body, the SMTP server will terminate the SMTP session
		with that error to match the behavior of the other callbacks.
	Return EX_IOERR (instead of 0) if a mail submission fails due to
		missing disk space in the mail queue.  Based on patch
		from Martin Poole of RedHat.
	CONFIG: Using FEATURE(`ldap_routing')'s `nodomain' argument would
		cause addresses not found in LDAP to be misparsed.
	CONFIG: Using a CN restriction did not work for TLS_Clt as it
		referred to a wrong macro.  Patch from John Gardiner
		Myers of Proofpoint.
	CONFIG: The option relaytofulladdress of FEATURE(`access_db')
		did not work if FEATURE(`relay_hosts_only') is used too.
		Problem noted by Kristian Shaw.
	CONFIG: The internal function lower() was broken and hence
		strcasecmp() did not work either, which could cause
		problems for some FEATURE()s if upper case arguments
		were used.  Patch from Vesa-Matti J Kari of the
		University of Helsinki.
	LIBMILTER: Fix internal check whether a milter application
		is compiled against the same version of libmilter as
		it is linked against (especially useful for dynamic
		libraries).
	LIBMILTER: Fix memory leak that occurred when smfi_setsymlist()
		was used.  Based on patch by Dan Lukes.
	LIBMILTER: Document the effect of SMFIP_HDR_LEADSPC for filters
		which add, insert, or replace headers.  From Benjamin
		Pineau.
	LIBMILTER: Fix error messages which refer to "select()" to be
		correct if SM_CONF_POLL is used.  Based on patch from
		John Nemeth.
	LIBSM: Fix handling of LDAP search failures where the error is
		carried in the search result itself, such as seen with
		OpenLDAP proxy servers.
	VACATION: Do not refer to a local variable outside its scope.
		Based on patch from Mark Costlow of Southwest Cyberport.
	Portability:
		Enable HAVE_NANOSLEEP for SunOS 5.11. Patch from
		John Beck of Sun Microsystems.
		Drop NISPLUS from default SunOS 5.11 map definitions.
		Patch from John Beck of Sun Microsystems.

8.14.3/8.14.3	2008/05/03
	During ruleset processing the generation of a key for a map
		lookup and the parsing of the default value was broken
		for some macros, e.g., $|, which caused the BlankSub
		character to be inserted into the workspace and thus
		failures, e.g., rules that should have matched did not.
	8.14.2 caused a regression: it accessed (macro) storage which was
		freed before. First instance of the problem reported by
		Matthew Dillon of DragonFlyBSD; variations of the same
		bug reported by Todd C. Miller of OpenBSD, Moritz
		Jodeit, and Dave Hayes.
	Improve pathname length checks for persistent host status.  Patch
		from Joerg Sonnenberger of DragonFlyBSD.
	Reword misleading SMTP reply text for FEATURE(`badmx').  Problem
		noted by Beth Halsema.
	The read timeout was fixed to be Timeout.datablock if STARTTLS
		was activated. This may cause problems if that value
		is lowered from its default. Problem noted by Jens Elkner.
	CONFIG: Using LOCAL_TLS_CLIENT caused the tls_client ruleset
		to operate incorrectly.  Problem found by Werner Wiethege.
	LIBMILTER: Omitting some protocol steps via the xxfi_negotiate()
		callback did not work properly. The patchlevel of
		libmilter has been set to 1 so a milter can determine
		whether libmilter contains this fix.
	MAKEMAP: If a delimiter is specified (-t) use that also when
		dumping a map.  Patch from Todd C. Miller of OpenBSD.
	Portability:
		Add support for Darwin 9.x (Mac OS X 10.5).
		Support shared libraries in Darwin 8 and 9.  Patch from
		Chris Behrens of Concentric.
		Add support for SCO OpenServer 6, patch from Boyd Gerber.
	DEVTOOLS: Clarify that confSHAREDLIBDIR requires a trailing slash.
	Added Files:

8.14.2/8.14.2	2007/11/01
	If a message was queued and it contained 8 bit characters in
		a From: or To: header, then those characters could be
		"mistaken" for internal control characters during a queue
		run and trigger various consistency checks.  Problem
		noted by Neil Rickert of Northern Illinois University.
	If MaxMimeHeaderLength is set to a value greater than 0 (which
		it is by default) then even if the Linelimit parameter
		is 0, sendmail corrupted in the non-transfer-encoding
		case every MAXLINE-1 characters.  Patch from John Gardiner
		Myers of Proofpoint.
	Setting the suboption DeliveryMode for DaemonPortOptions did not
		work in earlier 8.14 versions.
	Note: DeliveryMode=interactive is silently converted to
		background if a milter can reject or delete a recipient.
		Prior to 8.14 this happened only if milter could delete
		recipients.
	ClientRate should trigger when the limit was exceeded (as
		documented), not when it was reached.  Patch from
		John Beck of Sun Microsystems.
	Force a queue run for -qGqueuegroup even if no runners are
		specified (R=0) and forking (F=f) is requested.
	When multiple results are requested for a DNS map lookup
		(-z and -Z), return only those that are relevant for
		the query (not also those in the "additional section".)
	If the message transfer time to sendmail (when acting as server)
		exceeds Timeout.queuewarn or Timeout.queuereturn and
		the message is refused (by a milter), sendmail previously
		created a delivery status notification (DSN).  Patch
		from Doug Heath of The Hertz Corporation.
	A code change in Cyrus-SASL 2.1.22 for sasl_decode64() requires
		the MTA to deal with some input (i.e., "=") itself.
		Problem noted by Eliot Lear.
	sendmail counted a delivery as successful if PIPELINING is
		compiled in but not offered by the server and the
		delivery failed temporarily.  Patch from Werner Wiethege.
	If getting the result of an LDAP query times out then close the
		map so it will be reopened on the next lookup.  This
		should help "failover" configurations that specify more
		than one LDAP server.
	If check_compat returns $#discard then a "savemail panic" could
		be triggered under some circumstances (e.g., requiring
		a system which does not have the compile time flag
		HASFLOCK set). Based on patch by Motonori Nakamura
		of National Institute of Informatics, Japan.
	If a milter rejected a recipient, the count for nrcpts= in the
		logfile entry might have been wrong.  Problem found by
		Petra Humann of TU Dresden.
	If a milter invoked smfi_chgfrom() where ESMTP arguments are not
		NULL, the message body was lost.  Patch from Motonori
		Nakamura of National Institute of Informatics, Japan.
	sendmail(8) had a bogus space in -qGname.  Patch from Peng Haitao.
	CONTRIB: buildvirtuser: Preserve ownership and permissions when
		replacing files.
	CONTRIB: buildvirtuser: Skip dot-files (e.g., .cvsignore) when
		reading the /etc/mail/virtusers/ directory.
	CONTRIB: buildvirtuser: Emit warnings instead of exiting where
		appropriate.
	LIBMILTER: Fix ABI backwards compatibility so milters compiled
		against an older libmilter.so shared library can use an
		8.14 libmilter.so shared library.
	LIBMILTER: smfi_version() did not properly extract the patchlevel
		from the version number, however, the returned value was
		correct for the current libmilter version.

8.14.1/8.14.1	2007/04/03
	Even though a milter rejects a recipient the MTA will still keep
		it in its list of recipients and deliver to it if the
		transaction is accepted. This is a regression introduced
		in 8.14.0 due to the change for SMFIP_RCPT_REJ.  Bug
		found by Andy Fiddaman.
	The new DaemonPortOptions which begin with a lower case character
		could not be set in 8.14.0.
	If a server shut down the connection in response to a STARTTLS
		command, sendmail would log a misleading error message
		due to an internal inconsistency.  Problem found by
		Werner Wiethege.
	Document how some sendmail.cf options change the behavior of mailq.
		Noted by Paul Menchini of the North Carolina School of
		Science and Mathematics.
	CONFIG: Add confSOFT_BOUNCE m4 option for setting SoftBounce.
	CONFIG: 8.14.0's RELEASE_NOTES failed to mention the addition
		of the confMAX_NOOP_COMMANDS and confSHARED_MEMORY_KEY_FILE
		m4 options for setting MaxNOOPCommands and
		SharedMemoryKeyFile.
	CONFIG: Add confMILTER_MACROS_EOH and confMILTER_MACROS_DATA m4
		options for setting Milter.macros.eoh and Milter.macros.data.
	CONTRIB: Use flock() and fcntl() in qtool.pl if necessary.
		Patch from Daniel Carroll of Mesa State College.
	LIBMILTER: Make sure an unknown command does not affect the
		currently available macros.  Problem found by Andy Fiddaman.
	LIBMILTER: The MTA did not offer SMFIF_SETSYMLIST during option
		negotiation.  Problem reported by Bryan Costales.
	LIBMILTER: Fix several minor errors in the documentation.
		Patches from Bryan Costales.
	PORTABILITY FIXES:
		AIX 5.{1,2}: libsm/util.c failed to compile due to
			redefinition of several macros, e.g., SIG_ERR.
			Patch from Jim Pirzyk with assistance by Bob
			Booth, University of Illinois at Urbana-Champaign.
		Add support for QNX.6.  Patch from Sean Boudreau of QNX
			Software Systems.
	New Files:
		devtools/M4/depend/QNX6.m4
		devtools/OS/QNX.6.x
		include/sm/os/sm_os_qnx.h

	New Files added in 8.14.0, but not shown in the release notes entry:
		libmilter/docs/smfi_chgfrom.html
		libmilter/docs/smfi_version.html

8.14.0/8.14.0	2007/01/31
	Header field values are now 8 bit clean.  Notes:
		- header field names are still restricted to 7 bit.
		- RFC 2822 allows only 7 bit (US-ASCII) characters in
		  headers.
	Preserve spaces after the colon in a header.  Previously, any
		number of spaces after the colon would be changed to
		exactly one space.
	In some cases of deeply nested aliases/forwarding, mail can
		be silently lost.  Moreover, the MaxAliasRecursion
		limit may be reached too early, e.g., the counter
		may be off by a factor of 4 in case of a sequence of
		.forward files that refer to others.  Patch from
		Motonori Nakamura of Kyoto University.
	Fix a regression in 8.13.8: if InputMailFilters is set then
		"sendmail -bs" can trigger an assertion because the
		hostname of the client is undefined.  It is now set
		to "localhost" for the xxfi_connect() callback.
	Avoid referencing a freed variable during cleanup when terminating.
		Problem reported and diagnosed by Joe Maimon.
	New option HeloName to set the name for the HELO/EHLO command.
		Patch from Nik Clayton.
	New option SoftBounce to issue temporary errors (4xy) instead of
		permanent errors (5xy).  This can be useful for testing.
	New suboptions for DaemonPortOptions to set them individually
		per daemon socket:
			DeliveryMode	DeliveryMode
			refuseLA	RefuseLA
			delayLA		DelayLA
			queueLA		QueueLA
			children	MaxDaemonChildren
	New option -K for LDAP maps to replace %1 through %9 in the
		lookup key with the LDAP escaped contents of the
		arguments specified in the map lookup.  Loosely based
		on patch from Wolfgang Hottgenroth.
	Log the time after which a greet_pause delay triggered.  Patch
		from Nik Clayton.
	If a client is rejected via TCP wrapper or some other check
		performed by validate_connection() (in conf.c) then do
		not also invoke greet_pause.  Problem noted by Jim Pirzyk
		of the University of Illinois at Urbana-Champaign.
	If a client terminates the SMTP connection during a pause
		introduced by greet_pause, then a misleading message
		was logged previously.  Problem noted by Vernon Schryver
		et.al., patch from Matej Vela.
	New command "mstat" for control socket to provide "machine
		readable" status.
	New named config file rule check_eom which is called at the end
		of a message, its parameter is the size of the message.
	If the macro {addr_type} indicates that the current address
		is a header address it also distinguishes between
		recipient and sender addresses (as it is done for
		envelope addresses).
	When a macro is set in check_relay, then its value is accessible
		by all transactions in the same SMTP session.
	Increase size of key for ldap lookups to 1024 (MAXKEY).
	New option MaxNOOPCommands to override default of 20 for the
		number of "useless" commands before the SMTP server will
		slow down responding.
	New option SharedMemoryKeyFile: if shared memory support is
		enabled, the MTA can be asked to select a shared memory
		key itself by setting SharedMemoryKey to -1 and specifying
		a file where to store the selected key.
	Try to deal with open HTTP proxies that are used to send spam
		by recognizing some commands from them. If the first command
		from the client is GET, POST, CONNECT, or USER, then the
		connection is terminated immediately.
	New PrivacyOptions noactualrecipient to avoid putting
		X-Actual-Recipient lines in DSNs revealing the actual
		account that addresses map to.  Patch from Dan Harkless.
	New options B, z, and Z for DNS maps:
		-B: specify a domain that is always appended to queries.
		-z: specify the delimiter at which to cut off the result of
			a query if it is too long.
		-Z: specify the maximum number of entries to be concatenated
			to form the result of a lookup.
	New target "check" in the Makefile of libsm: instead of running tests
		implicitly while building libsm, they must be explicitly
		started by using "make check".
	Fixed some inconsistent checks for NULL pointers that have been
		reported by the SATURN tool which has been developed by
		Isil Dillig and Thomas Dillig of Stanford University.
	Fix a potential race condition caused by a signal handler for
		terminated child processes.  Problem noted by David F. Skoll.
	When a milter deleted a recipient, that recipient could cause a
		queue group selection. This has been disabled as it was not
		intended.
	New operator 'r' for the arith map to return a random number.
		Patch from Motonori Nakamura of Kyoto University.
	New compile time option MILTER_NO_NAGLE to turn off the Nagle
		algorithm for communication with libmilter ("cork" on Linux),
		which may improve the communication performance on some
		operating systems.  Patch from John Gardiner Myers of
		Proofpoint.
	If sendmail received input that contained a CR without subsequent LF
		(thus violating RFC 2821 (2.3.7)), it could previously
		generate an additional blank line in the output as the last
		line.
	Restarting persistent queue runners by sending a HUP signal to
		the "queue control process" (QCP) works now.
	Increase the length of an input line to 12288 to deal with
		really long lines during SMTP AUTH negotiations.
		Problem noted by Werner Wiethege.
	If ARPANET mode (-ba) was selected STARTTLS would fail (due to
		a missing initialization call for that case).  Problem
		noted by Neil Rickert of Northern Illinois University.
	If sendmail is linked against a library that initializes Cyrus-SASL
		before sendmail did it (such as libnss-ldap), then SMTP AUTH
		could fail for the sendmail client.  A patch by Moritz Both
		works around the API design flaw of Cyrus-SASLv2.
	CONFIG: Make it possible to unset the StatusFile option by
		undefining STATUS_FILE.  By not setting StatusFile,
		the MTA will not attempt to open a statistics file on
		each delivery.
	CONFIG: New FEATURE(`require_rdns') to reject messages from SMTP
		clients whose IP address does not have proper reverse DNS.
		Contributed by Neil Rickert of Northern Illinois University
		and John Beck of Sun Microsystems.
	CONFIG: New FEATURE(`block_bad_helo') to reject messages from SMTP
		clients which provide a HELO/EHLO argument which is either
		unqualified, or is one of our own names (i.e., the server
		name instead of the client name).  Contributed by Neil
		Rickert of Northern Illinois University and John Beck of
		Sun Microsystems.
	CONFIG: New FEATURE(`badmx') to reject envelope sender addresses
		(MAIL) whose domain part resolves to a "bad" MX record.
		Based on contribution from William Dell Wisner.
	CONFIG: New macros SMTP_MAILER_LL and RELAY_MAILER_LL to override
		the maximum line length of the smtp mailers.
	CONFIG: New option `relaytofulladdress' for FEATURE(`access_db')
		to allow entries in the access map to be of the form
			To:user@example.com	RELAY
	CONFIG: New subsuboptions eoh and data to specify the list of
		macros a milter should receive at those stages in the
		SMTP dialogue.
	CONFIG: New option confHELO_NAME for HeloName to set the name
		for the HELO/EHLO command.
	CONFIG: dnsbl and enhdnsbl can now also discard or quarantine
		messages by using those values as second argument.
		Patches from Nelson Fung.
	CONTRIB: cidrexpand uses a hash symbol as comment character and
		ignores everything after it unless it is in quotes or
		preceeded by a backslash.
	DEVTOOLS: New macro confMKDIR: if set to a program that creates
		directories, then it used for "make install" to create
		the required installation directories.
	DEVTOOLS: New macro confCCLINK to specify the linker to use for
		executables (defaults to confCC).
	LIBMILTER: A new version of the milter API has been created that
		has several changes which are listed below and documented
		in the webpages reachable via libmilter/docs/index.html.
	LIBMILTER: The meaning of the version macro SMFI_VERSION has been
		changed.  It now refers only to the version of libmilter,
		not to the protocol version (which is used only internally,
		it is not user/milter-programmer visible).  Additionally,
		a version function smfi_version() has been introduced such
		that a milter program can check the libmilter version also
		at runtime which is useful if a shared library is used.
	LIBMILTER: A new callback xxfi_negotiate() can be used to
		dynamically (i.e., at runtime) determine the available
		protocol actions and features of the MTA and also to
		specify which of these a milter wants to use.  This allows
		for more flexibility than hardcoding these flags in the
		xxfi_flags field of the smfiDesc structure.
	LIBMILTER: A new callback xxfi_data() is available so milters
		can act on the DATA command.
	LIBMILTER: A new callback xxfi_unknown() is available so milters
		can receive also unknown SMTP commands.
	LIBMILTER: A new return code SMFIS_NOREPLY has been added which
		can be used by the xxfi_header() callback provided the
		milter requested the SMFIP_NOHREPL protocol action.
	LIBMILTER: The new return code SMFIS_SKIP can be used in the
		xxfi_body() callback to skip over further body chunks
		and directly advance to the xxfi_eom() callback.  This
		is useful if a milter can make a decision based on the
		body chunks it already received without reading the entire
		rest of the body and the milter wants to invoke functions
		that are only available from the xxfi_eom() callback.
	LIBMILTER: A new function smfi_addrcpt_par() can be used to add
		new recipients including ESMTP parameters.
	LIBMILTER: A new function smfi_chgfrom() can be used to change the
		envelope sender including ESMTP parameters.
	LIBMILTER: A milter can now request to be informed about rejected
		recipients (RCPT) too.  This requires to set the protocol
		flag SMFIP_RCPT_REJ during option negotiation.  Whether
		a RCPT has been rejected can be checked by comparing the
		value of the macro {rcpt_mailer} with "error".
	LIBMILTER: A milter can now override the list of macros that it
		wants to receive from the MTA for each protocol step
		by invoking the function smfi_setsymlist() during option
		negotiation.
	LIBMILTER: A milter can receive header field values with all
		leading spaces by requesting the SMFIP_HDR_LEADSPC
		protocol action.  Also, if the flag is set then the MTA
		does not add a leading space to headers that are added,
		inserted, or replaced.
	LIBMILTER: If a milter sets the reply code to "421" for the HELO
		callback, the SMTP server will terminate the SMTP session
		with that error to match the behavior of all other callbacks.

8.13.8/8.13.8	2006/08/09
	Fix a regression in 8.13.7: if shared memory is activated, then
		the server can erroneously report that there is
		insufficient disk space.  Additionally make sure that
		an internal variable is set properly to avoid those
		misleading errors.  Based on patch from Steve Hubert
		of University of Washington.
	Fix a regression in 8.13.7: the PidFile could be removed after
		the process that forks the daemon exited, i.e., if
		sendmail -bd is invoked.  Problem reported by Kan Sasaki
		of Fusion Communications Corp. and Werner Wiethege.
	Avoid opening qf files if QueueSortOrder is "none".  Patch from
		David F. Skoll.
	Avoid a crash when finishing due to referencing a freed variable.
		Problem reported and diagnosed by Moritz Jodeit.
	CONTRIB: cidrexpand now deals with /0 by issuing the entire IPv4
		range (0..255).
	LIBMILTER: The "hostname" argument of the xxfi_connect() callback
		previously was the equivalent of {client_ptr}.  However,
		this did not match the documentation of the function, hence
		it has been changed to {client_name}.  See doc/op/op.me
		about these macros.

8.13.7/8.13.7	2006/06/14
	A malformed MIME structure with many parts can cause sendmail to
		crash while trying to send a mail due to a stack overflow,
		e.g., if the stack size is limited (ulimit -s).  This
		happens because the recursion of the function mime8to7()
		was not restricted.  The function is called for MIME 8 to
		7 bit conversion and also to enforce MaxMimeHeaderLength.
		To work around this problem, recursive calls are limited to
		a depth of MAXMIMENESTING (20); message content after this
		limit is treated as opaque and is not checked further.
		Problem noted by Frank Sheiness.
	The changes to the I/O layer in 8.13.6 caused a regression for
		SASL mechanisms that use the security layer, e.g.,
		DIGEST-MD5.  Problem noted by Robert Stampfli.
	If a timeout occurs while reading a message (during the DATA phase)
		a df file might have been left behind in the queue.
		This was another side effect of the changes to the I/O
		layer made in 8.13.6.
	Several minor problems have been fixed that were found by a
		Coverity scan of sendmail 8 as part of the NetBSD
		distribution. See http://scan.coverity.com/
		Note: the scan generated also a lot of "false positives",
		e.g., "error" reports about situations that cannot happen.
		Most of those code places are marked with lint(1) comments
		like NOTREACHED, but Coverity does not understand those.
		Hence an explicit assertion has been added in some cases
		to avoid those false positives.
	If the start of the sendmail daemon fails due to a configuration
		error then in some cases shared memory segments or pid
		files were not removed.
	If DSN support is disabled via access_db, then related ESMTP
		parameters for MAIL and RCPT should be rejected.  Problem
		reported by Akihiro Sagawa.
	Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding
		bug work-around.  Hence if sendmail is linked against
		either of these versions and compression is available,
		the padding bug work-around is turned off.  Based on
		patch from Victor Duchovni of Morgan Stanley.
	CONFIG: FEATURE(`dnsbl') and FEATURE(`enhdnsbl') used
		blackholes.mail-abuse.org as default domain for lookups,
		however, that list is no longer available.  To avoid
		further problems, no default value is available anymore,
		but an argument must be specified.
	Portability:
		Fix compilation on OSF/1 for sfsasl.c.  Patch from
		Pieter Bowman of the University of Utah.

8.13.6/8.13.6	2006/03/22
	SECURITY: Replace unsafe use of setjmp(3)/longjmp(3) in the server
		and client side of sendmail with timeouts in the libsm I/O
		layer and fix problems in that code.  Also fix handling of
		a buffer in sm_syslog() which could have been used as an
		attack vector to exploit the unsafe handling of
		setjmp(3)/longjmp(3) in combination with signals.
		Problem detected by Mark Dowd of ISS X-Force.
	Handle theoretical integer overflows that could triggered if
		the server accepted headers larger than the maximum
		(signed) integer value.  This is prevented in the default
		configuration by restricting the size of a header, and on
		most machines memory allocations would fail before reaching
		those values.  Problems found by Phil Brass of ISS.
	If a server returns 421 for an RSET command when trying to start
		another transaction in a session while sending mail, do
		not trigger an internal consistency check.  Problem found
		by Allan E Johannesen of Worcester Polytechnic Institute.
	If a server returns a 5xy error code (other than 501) in response
		to a STARTTLS command despite the fact that it advertised
		STARTTLS and that the code is not valid according to RFC
		2487 treat it nevertheless as a permanent failure instead
		of a protocol error (which has been changed to a
		temporary error in 8.13.5).  Problem reported by Jeff
		A. Earickson of Colby College.
	Clear SMTP state after a HELO/EHLO command.  Patch from John
		Myers of Proofpoint.
	Observe MinQueueAge option when gathering entries from the queue
		for sorting etc instead of waiting until the entries are
		processed.  Patch from Brian Fundakowski Feldman.
	Set up TLS session cache to properly handle clients that try to
		resume a stored TLS session.
	Properly count the number of (direct) child processes such that
		a configured value (MaxDaemonChildren) is not exceeded.
		Based on patch from Attila Bruncsak.
	LIBMILTER: Remove superfluous backslash in macro definition
		(libmilter.h).  Based on patch from Mike Kupfer of
		Sun Microsystems.
	LIBMILTER: Don't try to set SO_REUSEADDR on UNIX domain sockets.
		This generates an error message from libmilter on
		Solaris, though other systems appear to just discard the
		request silently.
	LIBMILTER: Deal with sigwait(2) implementations that return
		-1 and set errno instead of returning an error code
		directly.  Patch from Chris Adams of HiWAAY Informations
		Services.
	Portability:
		Fix compilation checks for closefrom(3) and statvfs(2)
		in NetBSD.  Problem noted by S. Moonesamy, patch from
		Andrew Brown.

8.13.5/8.13.5	2005/09/16
	Store the filesystem identifier of the df/ subdirectory (if it
		exists) in an internal structure instead of the base
		directory.  This structure is used decide whether there
		is enough free disk space when selecting a queue, hence
		without this change queue selection could fail if a df/
		subdirectory exists and is on a different filesystem
		than the base directory.
	Use the queue index of the df file (instead of the qf file) for
		checking whether a link(2) operation can be used to split
		an envelope across queue groups.  Problem found by
		Werner Wiethege.
	If the list of items in the queue is larger than the maximum
		number of items to process, sort the queue first and
		then cut the list off instead of the other way around.
		Patch from Matej Vela of Rudjer Boskovic Institute.
	Fix helpfile to show full entry for ETRN.  Problem noted by
		Penelope Fudd, patch from Neil Rickert of Northern Illinois
		University.
	FallbackSmartHost should also be tried on temporary errors.
		From John Beck of Sun Microsystems.
	When a server responds with 421 to the STARTTLS command then treat
		it as a temporary error, not as protocol error.  Problem
		noted by Andrey J. Melnikoff.
	Properly define two functions in libsm as static because their
		prototype used static too.  Patch from Peter Klein.
	Fix syntax errors in helpfile for MAIL and RCPT commands.
	LIBMILTER: When smfi_replacebody() is called with bodylen equals
		zero then do not silently ignore that call.  Patch from
		Gurusamy Sarathy of Active State.
	LIBMILTER: Recognize "421" also in a multi-line reply to terminate
		the SMTP session with that error.  Fix from Brian Kantor.
	Portability: New option HASSNPRINTF which can be set if the OS
			has a properly working snprintf(3) to get rid
			of the last two (safe) sprintf(3) calls in the
			source code.
		Add support for AIX 5.3.
		Add support for SunOS 5.11 (aka Solaris 11).
		Add support for Darwin 8.x.  Patch from Lyndon Nerenberg.
		OpenBSD 3.7 has removed support for NETISO.
	CONFIG: Add OSTYPE(freebsd6) for FreeBSD 6.X.
		Set DontBlameSendmail to AssumeSafeChown and
			GroupWritableDirPathSafe for OSTYPE(darwin).
			Patch from Lyndon Nerenberg.
		Some features still used 4.7.1 as enhanced status code which
			was supposed to be eliminated in 8.13.0 because some
			broken systems misinterpret it as a permanent error.
			Patch from Matej Vela of Rudjer Boskovic Institute.
		Some default values in a generated cf file did not match
			the defaults in the sendmail binary.  Problem noted
			by Mike Pechkin.

8.13.4/8.13.4	2005/03/27
	The bug fixes in 8.13.3 for connection handling uncovered a
		different error which could result in connections that
		stay in CLOSE_WAIT state due to a variable that was not
		properly initialized.  Problem noted by Michael Sims.
	Deal with empty hostnames in hostsignature().  This bug could lead
		to an endless loop when doing LMTP deliveries to another
		host.  Problem first reported by Martin Lathoud and
		tracked down by Gael Roualland.
	Make sure return parameters are initialized in getmxrr().  Problem
		found by Gael Roualland using valgrind.
	If shared memory is used and the RunAsUser option is set, then the
		owner and group of the shared memory segment is set to
		the ids specified RunAsUser and the access mode is set
		to 0660 to allow for updates by sendmail processes.
	The number of queue entries that is (optionally) kept in shared
		memory was wrong in some cases, e.g., envelope splitting
		and bounce generation.
	Undo a change made in 8.13.0 to silently truncate long strings
		in address rewriting because the message can be triggered
		for header checks where long strings are legitimate.
		Problem reported by Mary Verge DeSisto, and tracked
		down with the help of John Beck of Sun Microsystems.
	The internal stab map did not obey the -m flag.  Patch from
		Rob McMahon of Warwick University, England.
	The socket map did not obey the -f flag.  Problem noted by
		Dan Ringdahl, forwarded by Andrzej Filip.
	The addition of LDAP recursion in 8.13.0 broke enforcement of
		the LDAP map -1 argument which tells the MTA to only
		return success if and only if a single LDAP match is found.
	Add additional error checks in the MTA for milter communication
		to avoid a possible segmentation fault.  Based on patch
		by Joe Maimon.
	Do not trigger an assertion if X509_digest() returns success but
		does not assign a value to its output parameter.  Based
		on patch by Brian Kantor.
	Add more checks when resetting internal AUTH data (applies only
		to Cyrus SASL version 2).  Otherwise an SMTP session might
		be dropped after an AUTH failure.
	Portability:
		Add LA_LONGLONG as valid LA_TYPE type for systems that use
			"long long" to read load average data, e.g.,
			AIX 5.1 in 32 bit mode.  Note: this has to be set
			"by hand", it is not (yet) automatically detected.
			Problem noted by Burak Bilen.
		Use socklen_t for accept(), etc. on AIX 5.x.  This should
			fix problems when compiling in 64 bit mode.
			Problem first reported by Harry Meiert of
			University of Bremen.

8.13.3/8.13.3	2005/01/11
	Enhance handling of I/O errors, especially EOF, when STARTTLS
		is active.
	Make sure a connection is not reused after it has been closed
		due to a 421 error.  Problem found by Allan E Johannesen
		of Worcester Polytechnic Institute.
	Avoid triggering an assertion when sendmail is interrupted while
		closing a connection.  Problem found by Allan E Johannesen
		of Worcester Polytechnic Institute.
	Regression: a change in 8.13.2 caused sendmail not to try the
		next MX host (or FallbackMXhost if configured) when, at
		connection open, the current server returns a 4xy or 5xy
		SMTP reply code.  Problem noted by Mark Tranchant.

8.13.2/8.13.2	2004/12/15
	Do not split the first header even if it exceeds the internal
		buffer size.  Previously a part of such a header would
		end up in the body of the message.  Problem noted by
		Simple Nomad of BindView.
	Do not complain about "cataddr: string too long" when checking
		headers that do not contain RFC 2822 addresses.
		Problem noted by Rich Graves of Brandeis University.
	If a server returns a 421 reply to the RSET command between
		message deliveries, do not attempt to deliver any more
		messages on that connection.  This prevents bogus "Bad
		file number" recipient status.  Problem noted by
		Allan E Johannesen of Worcester Polytechnic Institute.
	Allow trailing white space in EHLO command as recommended by RFC
		2821.  Problem noted by Ralph Santagato of SBC Services.
	Deal with clients which use AUTH but negotiate a smaller buffer size
		for data exchanges than the value used by sendmail, e.g.,
		Cyrus IMAP lmtp server.  Based on patch by Jamie Clark.
	When passing ESMTP arguments for RCPT to a milter, do not cut
		them off at a comma.  Problem noted by Krzysztof Oledzki.
	Add more logging to milter change header functions to
		complement existing logging.  Based on patch from
		Gurusamy Sarathy of Active State.
	Include <lber.h> in include/sm/config.h when LDAPMAP is defined.
		Patch from Edgar Hoch of the University of Stuttgart.
	Fix DNS lookup if IPv6 is enabled when converting an IP address
		to a hostname for use with SASL.  Problem noted by Ken Jones;
		patch from Hajimu UMEMOTO.
	CONFIG: For consistency enable MODIFY_MAILER_FLAGS for the prog
		mailer.  Patch from John Beck of Sun Microsystems.
	LIBMILTER: It was possible that xxfi_abort() was called after
		xxfi_eom() for a message if some timeouts were triggered.
		Patch from Alexey Kravchuk.
	LIBMILTER: Slightly rearrange mutex use in listener.c to allow
		different threads to call smfi_opensocket() and smfi_main().
		Patch from Jordan Ritter of Cloudmark.
	MAIL.LOCAL: Properly terminate MBDB before exiting.  Problem
		noted by Nelson Fung.
	MAIL.LOCAL: make strip-mail.local used a wrong path to access
		mail.local.  Problem noted by William Park.
	VACATION: Properly terminate MBDB before exiting.  Problem noted
		by Nelson Fung.

8.13.1/8.13.1	2004/07/30
	Using the default AliasFile ldap: specification would cause the
		objectClasses of the LDAP response to be included in the
		alias expansion.  Problem noted by Brenden Conte of
		Rensselaer Polytechnic Institute.
	Fix support for a fallback smart host for system where DNS is
		(partially) available. From John Beck of Sun Microsystems.
	Fix SuperSafe=PostMilter behavior when a milter replaces a body
		but the data file is not yet stored on disk because it is
		smaller than the size of the memory buffer.  Problem noted
		by David Russell.
	Fix certificate revocation list support; if a CRL was specified
		but the other side presented a cert that was signed by
		a different (trusted) CA than the one which issued the CRL,
		verification would always fail.  Problem noted by Al Smith.
	Run mailer programs as the RunAsUser when RunAsUser is set and
		the F=S mailer flag is set without a U= mailer equate.
		Problem noted by John Gardiner Myers of Proofpoint.
	${nbadrcpts} was off by one if BadRcptThrottle is zero.
		Patch from Sung-hoon Choi of DreamWiz Inc.
	CONFIG: Emit a warning if FEATURE(`access_db') is used after
		FEATURE(`greet_pause') because then the latter will not
		use the access map.  Note: if no default value is given
		for FEATURE(`greet_pause') then it issues an error if
		FEATURE(`access_db') is not specified before it.
		Problem noted by Alexander Dalloz of University of
		Bielefeld.
	CONFIG: Invoke ruleset Local_greet_pause if FEATURE(`greet_pause')
		is used to give more flexibility for local changes.
	Portability:
		Fix a 64 bit problem in the socket map code.  Problem
			noted by Geoff Adams.
		NetBSD 2.0F has closefrom(3).  Patch from Andrew Brown.
		NetBSD can use sysctl(3) to get the number of CPUs in

8.13.0/8.13.0	2004/06/20
	Do not include AUTH data in a bounce to avoid leaking confidential
		information.  See also cf/README about MSP and the section
		"Providing SMTP AUTH Data when sendmail acts as Client".
		Problem noted by Neil Rickert of Northern Illinois
		University.
	Fix compilation error in libsm/clock.c for -D_FFR_SLEEP_USE_SELECT=n
		and -DSM_CONF_SETITIMER=0.  Problem noted by Juergen Georgi
		of RUS University of Stuttgart.
	Fix bug in conversion from 8bit to quoted-printable. Problem found
		by Christof Haerens, patch from Per Hedeland.
	Add support for LDAP recursion based on types given to attribute
		specifications in an LDAP map definition.  This allows
		LDAP queries to return a new query, a DN, or an LDAP
		URL which will in turn be queried.  See the ``LDAP
		Recursion'' section of doc/op/op.me for more information.
		Based on patch from Andrew Baucom.
	Extend the default LDAP specifications for AliasFile
		(O AliasFile=ldap:) and file classes (F{X}@LDAP) to
		include support for LDAP recursion via new attributes.
		See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section
		of cf/README for more information.
	New option for LDAP maps: the -w option allows you to specify the
		LDAP API/protocol version to use.  The default depends on
		the LDAP library.
	New option for LDAP maps: the -H option allows you to specify an
		LDAP URI instead of specifying the LDAP server via -h host
		and -p port.  This also allows for the use of LDAP over
		SSL and connections via named sockets if your LDAP
		library supports it.
	New compile time flag SM_CONF_LDAP_INITIALIZE: set this if
		ldap_initialize(3) is available (and LDAPMAP is set).
	If MaxDaemonChildren is set and a command is repeated too often
		during a SMTP session then terminate it just like it is
		done for too many bad SMTP commands.
	Basic connection rate control support has been added: the daemon
		maintains the number of incoming connections per client
		IP address and total in the macros {client_rate} and
		{total_rate}, respectively.  These macros can be used
		in the cf file to impose connection rate limits.
		A new option ConnectionRateWindowSize (default: 60s)
		determines the length of the interval for which the
		number of connections is stored.  Based on patch from
		Jose Marcio Martins da Cruz, Ecole des Mines de Paris.
	Add optional protection from open proxies and SMTP slammers which
		send SMTP traffic without waiting for the SMTP greeting.
		If enabled by the new ruleset greet_pause (see
		FEATURE(`greet_pause')), sendmail will wait the specified
		amount of time before sending the initial 220 SMTP
		greeting.  If any traffic is received before then, a 554
		SMTP response is sent and all SMTP commands are rejected
		during that connection.
	If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP
		server could sleep for a very long time.  Fix based on
		patch from Tadashi Kobayashi of IIJ.
	Fix a potential memory leak in persistent queue runners if the
		number of entries in the queue exceeds the limit of jobs.
		Problem noted by Steve Hubert of University of Washington.
	Do not use 4.7.1 as enhanced status code because some broken systems
		misinterpret it as a permanent error.
	New value for SuperSafe: PostMilter which will delay fsync() until
		all milters accepted the mail.  This can increase
		performance if many mails are rejected by milters due to
		body scans.  Based on patch from David F. Skoll.
	New macro {msg_id} which contains the value of the Message-Id:
		header, whether provided by the client or generated by
		sendmail.
	New macro {client_connections} which contains the number of open
		connections in the SMTP server for the client IP address.
		Based on patch from Jose Marcio Martins da Cruz, Ecole des
		Mines de Paris.
	sendmail will now remove its pidfile when it exits.  This was done
		to prevent confusion caused by running sendmail stop
		scripts two or more times, where the second and subsequent
		runs would report misleading error messages about sendmail's
		pid no longer existing.  See section 1.3.15 of doc/op/op.me
		for a discussion of the implications of this, including
		how to correct broken scripts which may have depended on
		the old behavior.  From John Beck of Sun Microsystems.
	Support per-daemon input filter lists which override the default
		filter list specified in InputMailFilters.  The filters
		can be listed in the I= equate of DaemonPortOptions.
	Do not add all domain prefixes of the hostname to class 'w'.  If
		your configuration relies on this behavior, you have to
		add those names to class 'w' yourself.  Problem noted
		by Sander Eerkes.
	Support message quarantining in the mail queue.  Quarantined
		messages are not run on normal queue displays or runs
		unless specifically requested with -qQ.  Quarantined queue
		files are named with an hf prefix instead of a qf prefix.
	The -q command line option now can specify which queue to display
		or run.  -qQ operates on quarantined queue items.  -qL
		operates on lost queue items.
	Restricted mail queue runs and displays can be done based on the
		quarantined reason using -qQtext to run or display
		quarantined items if the quarantine reason contains the
		given text.  Similarly, -q!Qtext will run or display
		quarantined items which do not have the given text in the
		quarantine reason.
	Items in the queue can be quarantined or unquarantined using the
		new -Q option.  See doc/op/op.me for more information.
	When displaying the quarantine mailq with 'mailq -qQ', the
		quarantine reason is shown in a new line prefixed by
		"QUARANTINE:".
	A new error code for the $#error mailer, $@ quarantine, can be used
		to quarantine messages in check_* (except check_compat) and
		header check rulesets.  The $: of the mailer triplet will
		be used for the quarantine reason.
	Add a new quarantine count to the mailstats collected.
	Add a new macro ${quarantine} which is the quarantine reason for a
		message if it is quarantined.
	New map type "socket" for a trivial query protocol over UNIX domain
		or TCP sockets (requires compile time option SOCKETMAP).
		See sendmail/README and doc/op/op.me for details as well as
		socketmapServer.pl and socketmapClient.pl in contrib.
		Code donated by Bastiaan Bakker of LifeLine Networks.
	Define new macro ${client_ptr} which holds the result of the PTR
		lookup for the client IP address.  Note: this is the same
		as ${client_name} if and only if ${client_resolve} is OK.
	Add a new macro ${nbadrcpts} which contains the number of bad
		recipients received so far in a transaction.
	Call check_relay with the value of ${client_name} to deal with bogus
		DNS entries.  See also FEATURE(`use_client_ptr').  Problem
		noted by Kai Schlichting.
	Treat Delivery-Receipt-To: headers the same as Return-Receipt-To:
		headers (turn them into DSNs).  Delivery-Receipt-To: is
		apparently used by SIMS (Sun Internet Mail System).
	Enable connection caching for LPC mailers.  Patch from Christophe
		Wolfhugel of France Telecom Oleane.
	Do not silently truncate long strings in address rewriting.
	Add support for Cyrus SASL version 2.  From Kenneth Murchison of
		Oceana Matrix Ltd.
	Add a new AuthOption=m flag to require the use of mechanisms which
		support mutual authentication.  From Kenneth Murchison of
		Oceana Matrix Ltd.
	Fix logging of TLS related problems (introduced in 8.12.11).
	The macros {auth_author} and {auth_authen} are stored in xtext
		format just like the STARTTLS related macros to avoid
		problems with parsing them.  Problem noted by Pierangelo
		Masarati of SysNet s.n.c.
	New option AuthRealm to set the authentication realm that is
		passed to the Cyrus SASL library.  Patch from Gary Mills
		of the University of Manitoba.
	Enable AUTH mechanism EXTERNAL if STARTTLS verification was
		successful, otherwise relaying would be allowed if
		EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS
		is active.
	Add basic support for certificate revocation lists.  Note: if a
		CRLFile is specified but the file is unusable, STARTTLS
		is disabled.  Based on patch by Ralf Hornik.
	Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms
		DIGEST-MD5 and LOGIN.
	Write pid to file also if sendmail only acts as persistent queue
		runner.  Proposed by Gary Mills of the University of Manitoba.
	Keep daemon pid file(s) locked so other daemons don't try to
		overwrite each other's pid files.
	Increase maximum length of logfile fields for {cert_subject} and
		{cert_issuer} from 128 to 256.  Requested by Christophe
		Wolfhugel of France Telecom.
	Log the TLS verification message on the STARTTLS= log line at
		LogLevel 12 or higher.
	If the MSP is invoked with the verbose option (-v) then it will
		try to use the SMTP command VERB to propagate this option
		to the MTA which in turn will show the delivery just like
		it was done before the default 8.12 separation of MSP and
		MTA.  Based on patch by Per Hedeland.
	If a daemon is refusing connections for longer than the time specified
		by the new option RejectLogInterval (default: 3 hours) due
		to high load, log this information.  Patch from John Beck
		of Sun Microsystems.
	Remove the ability for non-trusted users to raise the value of
		CheckpointInterval on the command line.
	New mailer flag 'B' to strip leading backslashes, which is a
		subset of the functionality of the 's' flag.
	New mailer flag 'W' to ignore long term host status information.
		Patch from Juergen Georgi of RUS University of Stuttgart.
	Enable generic mail filter API (milter) by default.  To turn
		it off, add -DMILTER=0 to the compile time options.
	An internal SMTP session discard flag was lost after an RSET/HELO/EHLO
		causing subsequent messages to be sent instead of being
		discarded.  This also caused milter callbacks to be called
		out of order after the SMTP session was reset.
	New option RequiresDirfsync to turn off the compile time flag
		REQUIRES_DIR_FSYNC at runtime.  See sendmail/README for
		further information.
	New command line option -D logfile to send debug output to
		the indicated log file instead of stdout.
	Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control
		queue return and warning times for delivery status
		notifications.
	New queue sort order option: 'n'one for not sorting the queue entries
		at all.
	Several more return values for ruleset srv_features have been added
		to enable/disable certain features in the server per
		connection.  See doc/op/op.me for details.
	Support for SMTP over SSL (smtps), activated by Modifier=s
		for DaemonPortOptions.
	Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when
		trying to canonify hostnames.  Suggested by Neil Rickert
		of Northern Illinois University.
	Add support for a fallback smart host (option FallbackSmartHost) to
		be tried as a last resort after all other fallbacks.  This
		is designed for sites with partial DNS (e.g., an accurate
		view of inside the company, but an incomplete view of
		outside).  From John Beck of Sun Microsystems.
	Enable timeout for STARTTLS even if client does not start the TLS
		handshake.  Based on patch by Andrey J. Melnikoff.
	Remove deprecated -v option for PH map, use -k instead.  Patch from
		Mark Roth of the University of Illinois at Urbana-Champaign.
	libphclient is version 1.2.x by default, if version 1.1.x is required
		then compile with -DNPH_VERSION=10100.  Patch from Mark Roth
		of the University of Illinois at Urbana-Champaign.
	Add Milter.macros.eom, allowing macros to be sent to milter
		applications for use in the xxfi_eom() callback.
	New macro {time} which contains the output of the time(3) function,
		i.e., the number of seconds since 0 hours, 0 minutes,
		0 seconds, January 1, 1970, Coordinated Universal Time (UTC).
	If check_relay sets the reply code to "421" the SMTP server will
		terminate the SMTP session with a 421 error message.
	Get rid of dead code that tried to access the environment variable
		HOSTALIASES.
	Deprecate the use of ErrorMode=write.  To enable this in 8.13
		compile with -DUSE_TTYPATH=1.
	Header check rulesets using $>+ (do not strip comments) will get
		the header value passed in without balancing quotes,
		parentheses, and angle brackets.  Based on patch from
		Oleg Bulyzhin.
	Do not complain and fix up unbalanced quotes, parentheses, and
		angle brackets when reading in rulesets.  This allows
		rules to be written for header checks to catch strings
		that contain quotes, parentheses, and/or angle brackets.
		Based on patch from Oleg Bulyzhin.
	Do not close socket when accept(2) in the daemon encounters
		some temporary errors like ECONNABORTED.
	Added list of CA certificates that are used by members of the
		sendmail consortium, see CACerts.
	Portability:
		Two new compile options have been added:
			HASCLOSEFROM	System has closefrom(3).
			HASFDWALK	System has fdwalk(3).
			Based on patch from John Beck of Sun Microsystems.
		The Linux kernel version 2.4 series has a broken flock() so
			change to using fcntl() locking until they can fix
			it.  Be sure to update other sendmail related
			programs to match locking techniques.
		New compile time option NEEDINTERRNO which should be set
			if <errno.h> does not declare errno itself.
		Support for UNICOS/mk and UNICOS/mp added, some changes for
			UNICOS.  Patches contributed by Aaron Davis and
			Brian Ginsbach, Cray Inc., and Manu Mahonen of
			Center for Scientific Computing.
		Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther).
		Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther).
		Remove path from compiler definition for Interix because
			Interix 3.0 and 3.5 put gcc in different locations.
			Also use <sys/mkdev.h> to get the correct
			major()/minor() definitions.  Based on feedback
			from Mark Funkenhauser.
	CONFIG: Add support for LDAP recursion to the default LDAP searches
		for maps via new attributes.  See the ``USING LDAP FOR
		ALIASES, MAPS, and CLASSES'' section of cf/README and
		cf/sendmail.schema for more information.
	CONFIG: Make sure confTRUSTED_USER is valid even if confRUN_AS_USER
		is of the form "user:group" when used for submit.mc.
		Problem noted by Carsten P. Gehrke, patch from Neil Rickert
		of Northern Illinois University.
	CONFIG: Add a new access DB value of QUARANTINE:reason which
		instructs the check_* (except check_compat) to quarantine
		the message using the given reason.
	CONFIG: Use "dns -R A" as map type for dnsbl (just as for enhdnsbl)
		instead of "host" to avoid problem with looking up other
		DNS records than just A.
	CONFIG: New option confCONNECTION_RATE_WINDOW_SIZE to define the
		length of the interval for which the number of incoming
		connections is maintained.
	CONFIG: New FEATURE(`ratecontrol') to set the limits for connection
		rate control for individual hosts or nets.
	CONFIG: New FEATURE(`conncontrol') to set the limits for the
		number of open SMTP connections for individual hosts or nets.
	CONFIG: New FEATURE(`greet_pause') enables open proxy and SMTP
		slamming protection described above.  The feature can
		take an argument specifying the milliseconds to wait and/or
		use the access database to look the pause time based on
		client hostname, domain, IP address, or subnet.
	CONFIG: New FEATURE(`use_client_ptr') to have check_relay use
		$&{client_ptr} as its first argument.  This is useful for
		rejections based on the unverified hostname of client,
		which turns on the same behavior as in earlier sendmail
		versions when delay_checks was not in use.  See also entry
		above about check_relay being invoked with ${client_name}.
	CONFIG: New option confREJECT_LOG_INTERVAL to specify the log
		interval when refusing connections for this long.
	CONFIG: Remove quotes around usage of confREJECT_MSG; in some cases
		this requires a change in a mc file.  Requested by
		Ted Roberts of Electronic Data Systems.
	CONFIG: New option confAUTH_REALM to set the authentication realm
		that is passed to the Cyrus SASL library.  Patch from
		Gary Mills of the University of Manitoba.
	CONFIG: Rename the (internal) classes {tls}/{src} to {Tls}/{Src}
		to follow the naming conventions.
	CONFIG: Add a third optional argument to local_lmtp to specify
		the A= argument.
	CONFIG: Remove the f flag from the default mailer flags of
		local_lmtp.
	CONFIG: New option confREQUIRES_DIR_FSYNC to turn off the compile
		time flag REQUIRES_DIR_FSYNC at runtime.
	CONFIG: New LOCAL_UUCP macro to insert rules into the generated
		cf file at the same place where MAILER(`uucp') inserts
		its rules.
	CONFIG: New options confTO_QUEUERETURN_DSN and confTO_QUEUEWARN_DSN
		to control queue return and warning times for delivery
		status notifications.
	CONFIG: New option confFALLBACK_SMARTHOST to define FallbackSmartHost.
	CONFIG: Add the mc file which has been used to create the cf
		file to the end of the cf file when using make in cf/cf/.
		Patch from Richard Rognlie.
	CONFIG: FEATURE(nodns) has been removed, it was a no-op since 8.9.
		Use ServiceSwitchFile to turn off DNS lookups, see
		doc/op/op.me.
	CONFIG: New option confMILTER_MACROS_EOM (sendmail Milter.macros.eom
		option) defines macros to be sent to milter applications for
		use in the xxfi_eom() callback.
	CONFIG: New option confCRL to specify file which contains
		certificate revocations lists.
	CONFIG: Add a new value (sendertoo) for the third argument to
		FEATURE(`ldap_routing') which will reject the SMTP
		MAIL From: command if the sender address doesn't exist
		in LDAP.  See cf/README for more information.
	CONFIG: Add a fifth argument to FEATURE(`ldap_routing') which
		instructs the rulesets on whether or not to do a domain
		lookup if a full address lookup doesn't match.  See cf/README
		for more information.
	CONFIG: Add a sixth argument to FEATURE(`ldap_routing') which
		instructs the rulesets on whether or not to queue the mail
		or give an SMTP temporary error if the LDAP server can't be
		reached.  See cf/README for more information.  Based on
		patch from Billy Ray Miller of Caterpillar.
	CONFIG: Experimental support for MTAMark, see cf/README for details.
	CONFIG: New option confMESSAGEID_HEADER to define a different
		Message-Id: header format.  Patch from Bastiaan Bakker
		of LifeLine Networks.
	CONTRIB: New version of cidrexpand which uses Net::CIDR.  From
		Derek J. Balling.
	CONTRIB: oldbind.compat.c has been removed due to security problems.
		Found by code inspection done by Reasoning, Inc.
	DEVTOOLS: Add an example file for devtools/Site/, contributed
		by Neil Rickert of Northern Illinois University.
	LIBMILTER: Add new function smfi_quarantine() which allows the
		filter's EOM routine to quarantine the current message.
		Filters which use this function must include the
		SMFIF_QUARANTINE flag in the registered smfiDesc structure.
	LIBMILTER: If a milter sets the reply code to "421", the SMTP server
		will terminate the SMTP session with that error.
	LIBMILTER: Upon filter shutdown, libmilter will not remove a
		named socket in the file system if it is running as root.
	LIBMILTER: Add new function smfi_progress() which allows the filter
		to notify the MTA that an EOM operation is still in progress,
		resetting the timeout.
	LIBMILTER: Add new function smfi_opensocket() which allows the filter
		to attempt to establish the interface socket, and detect
		failure to do so before calling smfi_main().
	LIBMILTER: Add new function smfi_setmlreply() which allows the
		filter to return a multi-line SMTP reply.
	LIBMILTER: Deal with more temporary errors in accept() by ignoring
		them instead of stopping after too many occurred.
		Suggested by James Carlson of Sun Microsystems.
	LIBMILTER: Fix a descriptor leak in the sample program found in
		docs/sample.html.  Reported by Dmitry Adamushko.
	LIBMILTER: The sample program also needs to use SMFIF_ADDRCPT.
		Reported by Carl Byington of 510 Software Group.
	LIBMILTER: Document smfi_stop() and smfi_setdbg().  Patches
		from Bryan Costales.
	LIBMILTER: New compile time option SM_CONF_POLL; define this if
		poll(2) should be used instead of select(2).
	LIBMILTER: New function smfi_insheader() and related protocol
		amendments to support header insertion operations.
	MAIL.LOCAL: Add support for hashed mail directories, see
		mail.local/README.  Contributed by Chris Adams of HiWAAY
		Informations Services.
	MAILSTATS: Display quarantine message counts.
	MAKEMAP: Add new flag -D to specify the comment character to use
		instead of '#'.
	VACATION: Add new flag -j to auto-respond to messages regardless of
		whether or not the recipient is listed in the To: or Cc:
		headers.
	VACATION: Add new flag -R to specify the envelope sender address

8.12.11/8.12.11	2004/01/18
	Use QueueFileMode when opening qf files.  This error was a
		regression in 8.12.10.  Problem detected and diagnosed
		Lech Szychowski of the Polish Power Grid Company.
	Properly count the number of queue runners in a work group and
		make sure the total limit of MaxQueueChildren is not
		exceeded.  Based on patch from Takayuki Yoshizawa of
		Techfirm, Inc.
	Take care of systems that can generate time values where the
		seconds can exceed the usual range of 0 to 59.
		Problem noted by Randy Diffenderfer of EDS.
	Avoid regeneration of identical queue identifiers by processes
		whose process id is the same as that of the initial
		sendmail process that was used to start the daemon.
		Problem noted by Randy Diffenderfer of EDS.
	When a milter invokes smfi_delrcpt() compare the supplied
		recipient address also against the printable addresses
		of the current list to deal with rewritten addresses.
		Based on patch from Sean Hanson of The Asylum.
	BadRcptThrottle now also works for addresses which return the
		error mailer, e.g., virtusertable entries with the
		right hand side error:.  Patch from Per Hedeland.
	Fix printing of 8 bit characters as octals in log messages.
		Based on patch by Andrey J. Melnikoff.
	Undo change of algorithm for MIME 7-bit base64 encoding to 8-bit
		text that has been introduced in 8.12.3.  There are some
		examples where the new code fails, but the old code works.
		To get the 8.12.3-8.12.10 version, compile sendmail with
		-DMIME7TO8_OLD=0.  If you have an example of improper
		7 to 8 bit conversion please send it to us.
	Return normal error code for unknown SMTP commands instead of
		the one specified by check_relay or a milter for a
		connection.  Problem noted by Andrzej Filip.
	Some ident responses contain data after the terminating CRLF which
		causes sendmail to log "POSSIBLE ATTACK...newline in string".
		To avoid this everything after LF is ignored.
	If the operating system supports O_EXLOCK and HASFLOCK is set
		then a possible race condition for creating qf files
		can be avoided.  Note: the race condition does not
		exist within sendmail, but between sendmail and an
		external application that accesses qf files.
	Log the proper options name for TLS related mising files for
		the CACertPath, CACertFile, and DHParameters options.
	Do not split an envelope if it will be discarded, otherwise df
		files could be left behind.  Problem found by Wolfgang
		Breyha.
	The use of the environment variables HOME and HOSTALIASES has been
		deprecated and will be removed in version 8.13.  This only
		effects configuration which preserve those variable via the
		'E' command in the cf file as sendmail clears out its entire
		environment.
	Portability:
		Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther).
		Solaris 10 has unsetenv(), patch from Craig Mohrman of
			Sun Microsystems.
	LIBMILTER: Add extra checks in case a broken MTA sends bogus data
		to libmilter.  Based on code review by Rob Grzywinski.
	SMRSH: Properly assemble commands that contain '&&' or '||'.
		Problem noted by Eric Lee of Talking Heads.
	New Files:

8.12.10/8.12.10	2003/09/24 (Released: 2003/09/17)
	SECURITY: Fix a buffer overflow in address parsing.  Problem
		detected by Michal Zalewski, patch from Todd C. Miller
		of Courtesan Consulting.
	Fix a potential buffer overflow in ruleset parsing.  This problem
		is not exploitable in the default sendmail configuration;
		only if non-standard rulesets recipient (2), final (4), or
		mailer-specific envelope recipients rulesets are used then
		a problem may occur.  Problem noted by Timo Sirainen.
	Accept 0 (and 0/0) as valid input for set MaxMimeHeaderLength.
		Problem noted by Thomas Schulz.
	Add several checks to avoid (theoretical) buffer over/underflows.
	Properly count message size when performing 7->8 or 8->7 bit MIME
		conversions.  Problem noted by Werner Wiethege.
	Properly compute message priority based on size of entire message,
		not just header.  Problem noted by Axel Holscher.
	Reset SevenBitInput to its configured value between SMTP
		transactions for broken clients which do not properly
		announce 8 bit data.  Problem noted by Stefan Roehrich.
	Set {addr_type} during queue runs when processing recipients.
		Based on patch from Arne Jansen.
	Better error handling in case of (very unlikely) queue-id conflicts.
	Perform better error recovery for address parsing, e.g., when
		encountering a comment that is too long.  Problem noted by
		Tanel Kokk, Union Bank of Estonia.
	Add ':' to the allowed character list for bogus HELO/EHLO
		checking.  It is used for IPv6 domain literals.  Patch from
		Iwaizako Takahiro of FreeBit Co., Ltd.
	Reset SASL connection context after a failed authentication attempt.
		Based on patch from Rob Siemborski of CMU.
	Check Berkeley DB compile time version against run time version
		to make sure they match.
	Do not attempt AAAA (IPv6) DNS lookups if IPv6 is not enabled
		in the kernel.
	When a milter adds recipients and one of them causes an error,
		do not ignore the other recipients.  Problem noted by
		Bart Duchesne.
	CONFIG: Use specified SMTP error code in mailertable entries which
		lack a DSN, i.e., "error:### Text".  Problem noted by
		Craig Hunt.
	CONFIG: Call Local_trust_auth with the correct argument.  Patch
		from Jerome Borsboom.
	CONTRIB: Better handling of temporary filenames for doublebounce.pl
		and expn.pl to avoid file overwrites, etc.  Patches from
		Richard A. Nelson of Debian and Paul Szabo.
	MAIL.LOCAL: Fix obscure race condition that could lead to an
		improper mailbox truncation if close() fails after the
		mailbox is fsync()'ed and a new message is delivered
		after the close() and before the truncate().
	MAIL.LOCAL: If mail delivery fails, do not leave behind a
		stale lockfile (which is ignored after the lock timeout).
		Patch from Oleg Bulyzhin of Cronyx Plus LLC.
	Portability:
		Port for AIX 5.2.  Thanks to Steve Hubert of University
			of Washington for providing access to a computer
			with AIX 5.2.
		setreuid(2) works on OpenBSD 3.3.  Patch from
			Todd C. Miller of Courtesan Consulting.
		Allow for custom definition of SMRSH_CMDDIR and SMRSH_PATH
			on all operating systems.  Patch from Robert Harker
			of Harker Systems.
		Use strerror(3) on Linux.  If this causes a problem on
			your Linux distribution, compile with
			-DHASSTRERROR=0 and tell sendmail.org about it.
	Added Files:
		devtools/OS/AIX.5.2

8.12.9/8.12.9	2003/03/29
	SECURITY: Fix a buffer overflow in address parsing due to
		a char to int conversion problem which is potentially
		remotely exploitable.  Problem found by Michal Zalewski.
		Note: an MTA that is not patched might be vulnerable to
		data that it receives from untrusted sources, which
		includes DNS.
	To provide partial protection to internal, unpatched sendmail MTAs,
		8.12.9 changes by default (char)0xff to (char)0x7f in
		headers etc.  To turn off this conversion compile with
		-DALLOW_255 or use the command line option -d82.101.
	To provide partial protection for internal, unpatched MTAs that may be
		performing 7->8 or 8->7 bit MIME conversions, the default
		for MaxMimeHeaderLength has been changed to 2048/1024.
		Note: this does have a performance impact, and it only
		protects against frontal attacks from the outside.
		To disable the checks and return to pre-8.12.9 defaults,
		set MaxMimeHeaderLength to 0/0.
	Do not complain about -ba when submitting mail.  Problem noted
		by Derek Wueppelmann.
	Fix compilation with Berkeley DB 1.85 on systems that do not
		have flock(2).  Problem noted by Andy Harper of Kings
		College London.
	Properly initialize data structure for dns maps to avoid various
		errors, e.g., looping processes.  Problem noted by
		Maurice Makaay of InterNLnet B.V.
	CONFIG: Prevent multiple application of rule to add smart host.
		Patch from Andrzej Filip.
	CONFIG: Fix queue group declaration in MAILER(`usenet').
	CONTRIB: buildvirtuser: New option -t builds the virtusertable
		text file instead of the database map.
	Portability:
		Revert wrong change made in 8.12.7 and actually use the
			builtin getopt() version in sendmail on Linux.
			This can be overridden by using -DSM_CONF_GETOPT=0
			in which case the OS supplied version will be used.

8.12.8/8.12.8	2003/02/11
	SECURITY: Fix a remote buffer overflow in header parsing by
		dropping sender and recipient header comments if the
		comments are too long.  Problem noted by Mark Dowd
		of ISS X-Force.
	Fix a potential non-exploitable buffer overflow in parsing the
		.cf queue settings and potential buffer underflow in
		parsing ident responses.  Problem noted by Yichen Xie of
		Stanford University Compilation Group.
	Fix ETRN #queuegroup command: actually start a queue run for
		the selected queue group.  Problem noted by Jos Vos.
	If MaxMimeHeaderLength is set and a malformed MIME header is fixed,
		log the fixup as "Fixed MIME header" instead of "Truncated
		MIME header".  Problem noted by Ian J Hart.
	CONFIG: Fix regression bug in proto.m4 that caused a bogus
		error message: "FEATURE() should be before MAILER()".
	MAIL.LOCAL: Be more explicit in some error cases, i.e., whether
		a mailbox has more than one link or whether it is not
		a regular file.  Patch from John Beck of Sun Microsystems.

8.12.7/8.12.7	2002/12/29
	Properly clean up macros to avoid persistence of session data
		across various connections.  This could cause session
		oriented restrictions, e.g., STARTTLS requirements,
		to erroneously allow a connection.  Problem noted
		by Tim Maletic of Priority Health.
	Do not lookup MX records when sorting the MSP queue.  The MSP
		only needs to relay all mail to the MTA.  Problem found
		by Gary Mills of the University of Manitoba.
	Do not restrict the length of connection information to 100
		characters in some logging statements.  Problem noted by
		Erik Parker.
	When converting an enhanced status code to an exit status, use
		EX_CONFIG if the first digit is not 2, 4, or 5 or if *.1.5
		is used.
	Reset macro $x when receiving another MAIL command.  Problem
		noted by Vlado Potisk of Wigro s.r.o.
	Don't bother setting the permissions on the build area statistics
		file, the proper permissions will be put on the file at
		install time.  This fixes installation over NFS for some
		users.  Problem noted by Martin J. Dellwo of 3-Dimensional
		Pharmaceuticals, Inc.
	Fix problem of decoding SASLv2 encrypted data.  Problem noted by
		Alex Deiter of Mobile TeleSystems, Komi Republic.
	Log milter socket open errors at MilterLogLevel 1 or higher instead
		of 11 or higher.
	Print early system errors to the console instead of silently
		exiting.  Problem noted by James Jong of IBM.
	Do not process a queue group if Runners is set to 0, regardless
		of whether F=f or sendmail is run in verbose mode (-v).
		The use of -qGname will still force queue group "name"
		to be run even if Runners=0.
	Change the level for logging the fact that a daemon is refusing
		connections due to high load from LOG_INFO to LOG_NOTICE.
		Patch from John Beck of Sun Microsystems.
	Use location information for submit.cf from NetInfo
		(/locations/sendmail/submit.cf) if available.
	Re-enable ForkEachJob which was lost in 8.12.0.  Problem noted by
		Neil Rickert of Northern Illinois University.
	Make behavior of /canon in debug mode consistent with usage in
		rulesets.  Patch from Shigeno Kazutaka of IIJ.
	Fix a potential memory leak in envelope splitting.  Problem noted
		by John Majikes of IBM.
	Do not try to share an mailbox database LDAP connection across
		different processes.  Problem noted by Randy Kunkee.
	Fix logging for undelivered recipients when the SMTP connection
		times out during message collection.  Problem noted by Neil
		Rickert of Northern Illinois University.
	Avoid problems with QueueSortOrder=random due to problems with
		qsort() on Solaris (and maybe some other operating systems).
		Problem noted by Stephan Schulz of Gruner+Jahr..
	If -f "" is specified, set the sender address to "<>".  Problem
		noted by Matthias Andree.
	Fix formatting problem of footnotes for plain text output on some
		versions of tmac.  Patch from Per Hedeland.
	Portability:
		Berkeley DB 4.1 support (requires at least 4.1.25).
		Some getopt(3) implementations in GNU/Linux are broken
			and pass a NULL pointer to an option which requires
			an argument, hence the builtin version of
			sendmail is used instead.  This can be overridden
			by using -DSM_CONF_GETOPT=0.  Problem noted by
			Vlado Potisk of Wigro s.r.o.
		Support for nph-1.2.0 from Mark D. Roth of the University
			of Illinois at Urbana-Champaign.
		Support for FreeBSD 5.0's MAC labeling from Robert Watson
			of the TrustedBSD Project.
		Support for reading the number of processors on an IRIX
			system from Michel Bourget of SGI.
		Support for UnixWare 7.1 based on input from Larry Rosenman.
		Interix support from Nedelcho Stanev of Atlantic Sky
			Corporation.
		Update Mac OS X/Darwin portability from Wilfredo Sanchez.
	CONFIG: Enforce tls_client restrictions even if delay_checks
		is used.  Problem noted by Malte Starostik.
	CONFIG: Deal with an empty hostname created via bogus
		DNS entries to get around access restrictions.
		Problem noted by Kai Schlichting.
	CONFIG: Use FEATURE(`msp', `[127.0.0.1]') in submit.mc by default
		to avoid problems with hostname resolution for localhost
		which on many systems does not resolve to 127.0.0.1 (or
		::1 for IPv6).  If you do not use IPv4 but only IPv6 then
		you need to change submit.mc accordingly, see the comment
		in the file itself.
	CONFIG: Set confDONT_INIT_GROUPS to True in submit.mc to avoid
		error messages from initgroups(3) on AIX 4.3 when sending
		mail to non-existing users. Problem noted by Mark Roth of
		the University of Illinois at Urbana-Champaign.
	CONFIG: Allow local_procmail to override local_lmtp settings.
	CONFIG: Always allow connections from 127.0.0.1 or IPv6:::1 to
		relay.
	CONTRIB: cidrexpand: Deal with the prefix tags that may be included
		in access_db.
	CONTRIB: New version of doublebounce.pl contributed by Leo Bicknell.
	LIBMILTER: On Solaris libmilter may get into an endless loop if
		an error in the communication from/to the MTA occurs.
		Patch from Gurusamy Sarathy of Active State.
	LIBMILTER: Ignore EINTR from sigwait(3) which may happen on Tru64.
		Patch from from Jose Marcio Martins da Cruz of Ecole
		Nationale Superieure des Mines de Paris.
	MAIL.LOCAL: Fix a truncation race condition if the close() on
		the mailbox fails.  Problem noted by Tomoko Fukuzawa of
		Sun Microsystems.
	MAIL.LOCAL: Fix a potential file descriptor leak if mkstemp(3)
		fails.  Patch from John Beck of Sun Microsystems.
	SMRSH: SECURITY: Only allow regular files or symbolic links to be
		used for a command.  Problem noted by David Endler of
		iDEFENSE, Inc.

8.12.6/8.12.6	2002/08/26
	Do not add the FallbackMXhost (or its MX records) to the list
		returned by the bestmx map when -z is used as option.
		Otherwise sendmail may act as an open relay if FallbackMXhost
		and FEATURE(`relay_based_on_MX') are used together.
		Problem noted by Alexander Ignatyev.
	Properly split owner- mailing list messages when SuperSafe is set
		to interactive.  Problem noted by Todd C. Miller of
		Courtesan Consulting.
	Make sure that an envelope is queued in the selected queue group
		even if some recipients are deleted or invalid.  Problem
		found by Chris Adams of HiWAAY Informations Services.
	Do not send a bounce message if a message is completely collected
		from the SMTP client.  Problem noted by Kari Hurtta of the
		Finnish Meteorological Institute.
	Provide an 'install-submit-st' target for sendmail/Makefile to
		install the MSP statistics file using the file named in the
		confMSP_STFILE devtools variable.  Requested by Jeff
		Earickson of Colby College.
	Queue up mail with a temporary error if setusercontext() fails
		during a delivery attempt.  Patch from Todd C. Miller of
		Courtesan Consulting.
	Fix handling of base64 encoded client authentication data for
		SMTP AUTH.  Patch from Elena Slobodnik of life medien GmbH.
	Set the OpenLDAP option LDAP_OPT_RESTART so the client libraries
		restart interrupted system calls.  Problem noted by Luiz
		Henrique Duma of BSIOne.
	Prevent a segmentation fault if a program passed a NULL envp using
		execve().
	Document a problem with the counting of queue runners that may
		cause delays if MaxQueueChildren is set too low. Problem
		noted by Ian Duplisse of Cable Television Laboratories, Inc.
	If discarding a message based on a recipient, don't try to look up
		the recipient in the mailbox database if F=w is set.  This
		allows users to discard bogus recipients when dealing with
		spammers without tipping them off.  Problem noted by Neil
		Rickert of Northern Illinois University.
	If applying a header check to a header with unstructured data,
		e.g., Subject:, then do not run syntax checks that are
		supposed for addresses on the header content.
	Count messages rejected/discarded via the check_data ruleset.
	Portability:
		Fix compilation on systems which do not allow simple
			copying of the variable argument va_list.  Based on
			fix from Scott Walters.
		Fix NSD map open bug.  From Michel Bourget of SGI.
		Add some additional IRIX shells to the default shell
			list.  From Michel Bourget of SGI.
		Fix compilation issues on Mac OS X 10.2 (Darwin 6.0).
			NETISO support has been dropped.
	CONFIG: There was a seemingly minor change in 8.12.4 with respect
		to handling entries of IP nets/addresses with RHS REJECT.
		These would be rejected in check_rcpt instead of only
		being activated in check_relay.  This change has been made to
		avoid potential bogus temporary rejection of relay attempts
		"450 4.7.1 Relaying temporarily denied. Cannot resolve PTR
		record for ..." if delay_checks is enabled.  However, this
		modification causes a change of behavior if an IP net/address
		is listed in the access map with REJECT and a host/domain
		name is listed with OK or RELAY, hence it has been reversed
		such that the behavior of 8.12.3 is restored.  The original
		change was made on request of Neil Rickert of Northern
		Illinois University, the side effect has been found by
		Stefaan Van Hoornick.
	CONFIG: Make sure delay_checks works even for sender addresses
		using the local hostname ($j) or domains in class {P}.
		Based on patch from Neil Rickert of Northern Illinois
		University.
	CONFIG: Fix temporary error handling for LDAP Routing lookups.
		Fix from Andrzej Filip.
	CONTRIB: New version of etrn.pl script and external man page
		(etrn.0) from John Beck of Sun Microsystems.
	LIBMILTER: Protect a free(3) operation from being called with a
		NULL pointer.  Problem noted by Andrey J. Melnikoff.
	LIBMILTER: Protect against more interrupted select() calls.  Based
		on patch from Jose Marcio Martins da Cruz of Ecole Nationale
		Superieure des Mines de Paris.
	New Files:
		contrib/etrn.0

8.12.5/8.12.5	2002/06/25
	SECURITY: The DNS map can cause a buffer overflow if the user
		specifies a dns map using TXT records in the configuration
		file and a rogue DNS server is queried.  None of the
		sendmail supplied configuration files use this option hence
		they are not vulnerable.  Problem noted independently by
		Joost Pol of PINE Internet and Anton Rang of Sun Microsystems.
	Unprintable characters in responses from DNS servers for the DNS
		map type are changed to 'X' to avoid potential problems
		with rogue DNS servers.
	Require a suboption when setting the Milter option.  Problem noted
		by Bryan Costales.
	Do not silently overwrite command line settings for
		DirectSubmissionModifiers.  Problem noted by Bryan
		Costales.
	Prevent a segmentation fault when clearing the event list by
		turning off alarms before checking if event list is
		empty.  Problem noted by Allan E Johannesen of Worcester
		Polytechnic Institute.
	Close a potential race condition in transitioning a memory buffered
		file onto disk.  From Janani Devarajan of Sun Microsystems.
	Portability:
		Include paths.h on Linux systems running glibc 2.0 or later
			to get the definition for _PATH_SENDMAIL, used by
			rmail and vacation.  Problem noted by Kevin
			A. McGrail of Peregrine Hardware.
		NOTE: Linux appears to have broken flock() again.  Unless
			the bug is fixed before sendmail 8.13 is shipped,
			8.13 will change the default locking method to
			fcntl() for Linux kernel 2.4 and later.  You may
			want to do this in 8.12 by compiling with
			-DHASFLOCK=0.  Be sure to update other sendmail
			related programs to match locking techniques.

8.12.4/8.12.4	2002/06/03
	SECURITY: Inherent limitations in the UNIX file locking model
		can leave systems open to a local denial of service
		attack.  Be sure to read the "FILE AND MAP PERMISSIONS"
		section of the top level README for more information.
		Problem noted by lumpy.
	Use TempFileMode (defaults to 0600) for the permissions of PidFile
		instead of 0644.
	Change the default file permissions for new alias database files
		from 0644 to 0640.  This can be overridden at compile time
		by setting the DBMMODE macro.
	Fix a potential core dump problem if the environment variable
		NAME is set.  Problem noted by Beth A. Chaney of
		Purdue University.
	Expand macros before passing them to libmilter.  Problem noted
		by Jose Marcio Martins da Cruz of Ecole Nationale
		Superieure des Mines de Paris.
	Rewind the df (message body) before truncating it when libmilter
		replaces the body of a message.  Problem noted by Gisle Aas
		of Active State.
	Change SMTP reply code for AUTH failure from 500 to 535 and the
		initial zero-length response to "=" per RFC 2554.  Patches
		from Kenneth Murchison of Oceana Matrix Ltd.
	Do not try to fix broken message/rfc822 MIME attachments by
		inserting a MIME-Version: header when MaxMimeHeaderLength
		is set and no 8 to 7 bit conversion is needed.  Based on
		patch from Rehor Petr of ICZ (Czech Republic).
	Do not log "did not issue MAIL/EXPN/VRFY/ETRN" if the connection
		is rejected anyway.  Noted by Chris Loelke.
	Mention the submission mail queue in the mailq man page.  Requested
		by Bill Fenner of AT&T.
	Set ${msg_size} macro when reading a message from the command line
		or the queue.
	Detach from shared memory before dropping privileges back to
		user who started sendmail.
	If AllowBogusHELO is set to false (default) then also complain if
		the argument to HELO/EHLO contains white space.  Suggested
		by Seva Gluschenko of Cronyx Plus.
	Allow symbolicly linked forward files in writable directory paths
		if both ForwardFileInUnsafeDirPath and
		LinkedForwardFileInWritableDir DontBlameSendmail options
		are set.  Problem noted by Werner Spirk of
		Leibniz-Rechenzentrum Munich.
	Portability:
		Operating systems that lack the ftruncate() call will not
			be able to use Milter's body replacement feature.
			This only affects Altos, Maxion, and MPE/iX.
		Digital UNIX 5.0 has changed flock() semantics to be
			non-compliant.  Problem noted by Martin Mokrejs of
			Charles University in Prague.
		The sparc64 port of FreeBSD 5.0 now supports shared
			memory.
	CONFIG: FEATURE(`preserve_luser_host') needs the macro map.
		Problem noted by Andrzej Filip.
	CONFIG: Using 'local:' as a mailertable value with
		FEATURE(`preserve_luser_host') and LUSER_RELAY caused mail
		to be misaddressed.  Problem noted by Andrzej Filip.
	CONFIG: Provide a workaround for DNS based rejection lists that
		fail for AAAA queries.  Problem noted by Chris Boyd.
	CONFIG: Accept the machine's hostname as resolvable when checking
		the sender address.  This allows locally submitted mail to
		be accepted if the machine isn't connected to a nameserver
		and doesn't have an /etc/hosts entry for itself.  Problem
		noted by Robert Watson of the TrustedBSD Project.
	CONFIG: Use deferred expansion for checking the ${deliveryMode}
		macro in case the SMTP VERB command is used.  Problem
		noted by Bryan Costales.
	CONFIG: Avoid a duplicate '@domain' virtusertable lookup if no
		matches are found.  Fix from Andrzej Filip.
	CONFIG: Fix wording in default dnsbl rejection message.  Suggested
		by Lou Katz of Metron Computerware, Ltd.
	CONFIG: Add mailer cyrusv2 for Cyrus V2.  Contributed by
		Kenneth Murchison of Oceana Matrix Ltd.
	CONTRIB: Fix wording in default dnsblaccess rejection message to

	DEVTOOLS: Add new option for access mode of statistics file,
		confSTMODE, which specifies the permissions when initially
		installing the sendmail statistics file.
	LIBMILTER: Mark the listening socket as close-on-exec in case
		a user's filter starts other applications.
	LIBSM: Allow the MBDB initialize, lookup, and/or terminate
		functions in SmMbdbTypes to be set to NULL.
	MAKEMAP: Change the default file permissions for new databases from
		0644 to 0640.  This can be overridden at compile time
		by setting the DBMMODE macro.
	SMRSH: Fix man page bug: replace SMRSH_CMDBIN with SMRSH_CMDDIR.

8.12.3/8.12.3	2002/04/05
	NOTICE: In general queue files should not be moved if queue groups
		are used.  In previous versions this could cause mail
		not to be delivered if a queue file is repeatedly moved
		by an external process whenever sendmail moved it back
		into the right place.  Some precautions have been taken
		to avoid moving queue files if not really necessary.
		sendmail may use links to refer to queue files and it
		may store the path of data files in queue files.  Hence
		queue files should not be moved unless those internals
		are understood and the integrity of the files is not
		compromised.  Problem noted by Anne Bennett of Concordia
		University.
	If an error mail is created, and the mail is split across different
		queue directories, and SuperSafe is off, then write the mail
		to disk before splitting it, otherwise an assertion is
		triggered.  Problem tracked down by Henning Schmiedehausen
		of INTERMETA.
	Fix possible race condition that could cause sendmail to forget
		running queues.  Problem noted by Jeff Wasilko of smoe.org.
	Handle bogus qf files better without triggering assertions.
		Problem noted by Guy Feltin.
	Protect against interrupted select() call when enforcing Milter
		read and write timeouts.  Patch from Gurusamy Sarathy of
		ActiveState.
	Matching queue IDs with -qI should be case sensitive.  Problem
		noted by Anne Bennett of Concordia University.
	If privileges have been dropped, don't try to change group ID to
		the RunAsUser group.  Problem noted by Neil Rickert of
		Northern Illinois University.
	Fix SafeFileEnvironment path munging when the specified path
		contains a trailing slash.  Based on patch from Dirk Meyer
		of Dinoex.
	Do not limit sendmail command line length to SM_ARG_MAX (usually
		4096).  Problem noted by Allan E Johannesen of Worcester
		Polytechnic Institute.
	Clear full name of sender for each new envelope to avoid bogus data
		if several mails are sent in one session and some of them
		do not have a From: header.  Problem noted by Bas Haakman.
	Change timeout check such that cached information about a connection
		will be immediately invalid if ConnectionCacheTimeout is zero.
		Based on patch from David Burns of Portland State University.
	Properly count message size for mailstats during mail collection.
		Problem noted by Werner Wiethege.
	Log complete response from LMTP delivery agent on failure.  Based on
		patch from Motonori Nakamura of Kyoto University.
	Provide workaround for getopt() implementations that do not catch
		missing arguments.
	Fix the message size calculation if the message body is replaced by
		a milter filter and buffered file I/O is being used.
		Problem noted by Sergey Akhapkin of Dr.Web.
	Do not honor SIGUSR1 requests if running with extra privileges.
		Problem noted by Werner Wiethege.
	Prevent a file descriptor leak on mail delivery if the initial
		connect fails and DialDelay is set.  Patch from Servaas
		Vandenberghe of Katholieke Universiteit Leuven.
	Properly deal with a case where sendmail is called by root running
		a set-user-ID (non-root) program.  Problem noted by Jon
		Lusky of ISS Atlanta.
	Avoid leaving behind stray transcript (xf) files if multiple queue
		directories are used and mail is sent to a mailing list
		which has an owner- alias.  Problem noted by Anne Bennett
		of Concordia University.
	Fix class map parsing code if optional key is specified.  Problem
		found by Mario Nigrovic.
	The SMTP daemon no longer tries to fix up improperly dot-stuffed
		incoming messages.  A leading dot is always stripped by the
		SMTP receiver regardless of whether or not it is followed by
		another dot.  Problem noted by Jordan Ritter of darkridge.com.
	Fix corruption when doing automatic MIME 7-bit quoted-printable or
		base64 encoding to 8-bit text.  Problem noted by Mark
		Elvers.
	Correct the statistics gathered for total number of connections.
		Instead of being the exact same number as the total number
		of messages (T line in mailstats) it now represents the
		total number of TCP connections.
	Be more explicit about syntax errors in addresses, especially
		non-ASCII characters, and properly create DSNs if necessary.
		Problem noted by Leena Heino of the University of Tampere.
	Prevent small timeouts from being lost on slow machines if itimers
		are used.  Problem noted by Suresh Ramasubramanian.
	Prevent a race condition on child cleanup for delivery to files.
		Problem noted by Fletcher Mattox of the University of
		Texas.
	Change the SMTP error code for temporary map failures from 421
		to 451.
	Do not assume that realloc(NULL, size) works on all OS (this was
		only done in one place: queue group creation).  Based on
		patch by Bryan Costales.
	Initialize Timeout.iconnect in the code to prevent randomly short
		timeouts.  Problem noted by Bradley Watts of AT&T Canada.
	Do not try to send a second SMTP QUIT command if the remote
		responds to a MAIL command with a 421 reply or on I/O
		errors.  By doing so, the host was marked as having a
		temporary problem and other mail destined for that host was
		queued for the next queue run.  Problem noted by Fletcher
		Mattox of the University of Texas, Allan E Johannesen of
		Worcester Polytechnic Institute, Larry Greenfield of CMU,
		and Neil Rickert of Northern Illinois University.
	Ignore error replies from the SMTP QUIT command (including servers
		which drop the connection instead of responding to the
		command).
	Portability:
		Check LDAP_API_VERSION to determine if ldap_memfree() is
			available.
		Define HPUX10 when building on HP-UX 10.X.  That platform
			now gets the proper _PATH_SENDMAIL and SMRSH_CMDDIR
			settings.  Patch from Elias Halldor Agustsson of
			Skyrr.
		Fix dependency building on Mac OS X and Darwin.  Problem
			noted by John Beck.
		Preliminary support for the sparc64 port of FreeBSD 5.0.
		Add /sbin/sh as an acceptable user shell on HP-UX.  From
			Rajesh Somasund of Hewlett-Packard.
	CONFIG: Add FEATURE(`authinfo') to allow a separate database for
		SMTP AUTH information.  This feature was actually added in
		8.12.0 but a release note was not included.
	CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce
		parameter is set and the LDAP lookup returns a temporary
		error.
	CONFIG: Honor FEATURE(`relay_hosts_only') when using
		FEATURE(`relay_mail_from', `domain').  Problem noted by
		Krzysztof Oledzki.
	CONFIG: FEATURE(`msp') now disables any type of alias
		initialization as aliases are not needed for the MSP.
	CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp')
		is in use.  Patch from Andrzej Filip.
	CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of
		`localhost' and turns on MX lookups for the SMTP mailers.
		This will only have an effect if a parameter is specified,
		i.e., an MX lookup will be performed on the hostname unless
		it is embedded in square brackets.  Problem noted by
		Theo Van Dinter of Collective Technologies.
	CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in
		submit.cf) to use $TZ for time stamps.  This is a compromise
		to allow for the proper time zone on systems where the
		default results in misleading time stamps. That is, syslog
		time stamps and Date headers on submitted mail will use the
		user's $TZ setting.  Problem noted by Mark Roth of the
		University of Illinois at Urbana-Champaign, solution proposed
		by Neil Rickert of Northern Illinois University.
	CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID
		binary.  Adjust local mailer flags accordingly.  Problem
		noted by John Beck.
	CONTRIB: Add a warning to qtool.pl to not move queue files around
		if queue groups are used.
	CONTRIB: buildvirtuser: Add -f option to force rebuild.
	CONTRIB: smcontrol.pl: Add -f option to specify control socket.
	CONTRIB: smcontrol.pl: Add support for 'memdump' command.
		Suggested by Bryan Costales.
	DEVTOOLS: Add dependency generation for test programs.
	LIBMILTER: Remove conversion of port number for the socket
		structure that is passed to xxfi_connect().  Notice:
		this fix requires that sendmail and libmilter both have
		this change; mixing versions may lead to wrong port
		values depending on the endianness of the involved systems.
		Problem noted by Gisle Aas of ActiveState.
	LIBMILTER: If smfi_setreply() sets a custom reply code of '4XX' but
		SMFI_REJECT is returned, ignore the custom reply.  Do the
		same if '5XX' is used and SMFI_TEMPFAIL is returned.
	LIBMILTER: Install include files in ${INCLUDEDIR}/libmilter/ as
		required by mfapi.h.  Problem noted by Jose Marcio Martins
		da Cruz of Ecole Nationale Superieure des Mines de Paris.
	LIBSM: Add SM_CONF_LDAP_MEMFREE as a configuration define.  Set
		this to 1 if your LDAP client libraries include
		ldap_memfree().
	LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X
		and NDBM on systems with the O_EXLOCK open(2) flag.
	SMRSH: Fix compilation problem on some operating systems.  Problem
		noted by Christian Krackowizer of schuler technodat GmbH.
	VACATION: Allow root to operate on user vacation databases.  Based
		on patch from Greg Couch of the University of California,
		San Francisco.
	VACATION: Don't ignore -C option.  Based on patch by Bryan Costales.
	VACATION: Clarify option usage in the man page.  Problem noted by
		Joe Barbish.

8.12.2/8.12.2	2002/01/13
	Don't complain too much if stdin, stdout, or stderr are missing
		at startup, only log an error message.
	Fix potential problem if an unknown operation mode (character
		following -b) has been specified.
	Prevent purgestat from looping even if someone changes the
		permissions or owner of hoststatus files.  Problem noted

	Properly record dropped connections in persistent host status.
		Problem noted by Ulrich Windl of the Universitat
		Regensburg.
	Remove newlines from recipients read via sendmail -t to prevent
		SMTP protocol errors when sending the RCPT command.
		Problem noted by William D. Colburn of the New Mexico
		Institute of Mining and Technology.
	Only log milter body replacements once instead of for each body
		chunk sent by a filter.  Problem noted by Kari Hurtta of
		the Finnish Meteorological Institute.
	In 8.12.0 and 8.12.1, the headers were mistakenly not included in
		the message size calculation.  Problem noted by Kari Hurtta
		of the Finnish Meteorological Institute.
	Since 8.12 no longer forks at the SMTP MAIL command, the daemon
		needs to collect children status to avoid zombie processes.
		Problem noted by Chris Adams of HiWAAY Informations Services.
	Shut down "nullserver" and ETRN-only connections after 25 bad
		commands are issued.  This makes it consistent with normal
		SMTP connections.
	Avoid duplicate logging of milter rejections.  Problem noted by
		William D. Colburn of the New Mexico Institute of Mining
		and Technology.
	Error and delay DSNs were being sent to postmaster instead of the
		message sender if the sender had used a deprecated RFC822
		source route.  Problem noted by Kari Hurtta of the Finnish
		Meteorological Institute.
	Fix FallbackMXhost behavior for temporary errors during address
		parsing.  Problem noted by Jorg Bielak from Coastal Web
		Online.
	For systems on which stat(2) does not return a value for st_blksize
		that is the "optimal blocksize for I/O" three new compile
		time flags are available: SM_IO_MAX_BUF_FILE, SM_IO_MIN_BUF,
		and SM_IO_MAX_BUF, which define an upper limit for
		regular files, and a lower and upper limit for other file
		types, respectively.
	Fix a potential deadlock if two events are supposed to occur at
		exactly the same time.  Problem noted by Valdis Kletnieks
		of Virginia Tech.
	Perform envelope splitting for aliases listed directly in the
		alias file, not just for include/.forward files.
		Problem noted by John Beck of Sun Microsystems.
	Allow selection of queue group for mailq using -qGgroup.
		Based on patch by John Beck of Sun Microsystems.
	Make sure cached LDAP connections used my multiple maps in the same
		process are closed.  Patch from Taso N. Devetzis.
	If running as root, allow reading of class files in protected
		directories.  Patch from Alexander Talos of the University
		of Vienna.
	Correct a few LDAP related memory leaks.  Patch from David Powell
		of Sun Microsystems.
	Allow specification of an empty realm via the authinfo ruleset.
		This is necessary to interoperate as an SMTP AUTH client
		with servers that do not support realms when using
		CRAM-MD5.  Problem noted by Bjoern Voigt of TU Berlin.
	Avoid a potential information leak if AUTH PLAIN is used and the
		server gets stuck while processing that command.  Problem
		noted by Chris Adams from HiWAAY Informations Services.
	In addition to printing errors when parsing recipients during
		command line invocations log them to make it simpler
		to understand possible DSNs to postmaster.
	Do not use FallbackMXhost on mailers which have the F=0 flag set.
	Allow local mailers (F=l) to specify a host for TCP connections
		instead of forcing localhost.
	Obey ${DESTDIR} for installation of the client mail queue and
		submit.cf.  Patch from Peter 'Luna' Runestig.
	Re-enable support for -M option which was broken in 8.12.1.  Problem
		noted by Neil Rickert of Northern Illinois University.
	If a remote server violates the SMTP standard by unexpectedly
		dropping the connection during an SMTP transaction, stop
		sending commands.  This prevents bogus "Bad file number"
		recipient status.  Problem noted by Allan E Johannesen of
		Worcester Polytechnic Institute.
	Do not use a size estimate of 100 for postmaster bounces, it's
		almost always too small; do not guess the size at all.
	New VENDOR_DEC for Compaq/DEC.  Requested by James Seagraves of
		Compaq Computer Corp.
	Fix DaemonPortOptions IPv6 address parsing such that ::1 works
		properly.  Problem noted by Valdis Kletnieks of Virginia
		Tech.
	Portability:
		Fix IPv6 network interface probing on HP-UX 11.X.  Based on

		Use proper type for a 32-bit integer on SINIX.  From Ganu
			Sachin of Siemens.
		Set SM_IO_MIN_BUF (4K) and SM_IO_MAX_BUF (8K) for HP-UX.
		Reduce optimization from +O3 to +O2 on HP-UX 11.  This

8.12.1/8.12.1	2001/10/01
	SECURITY: Check whether dropping group privileges actually succeeded
		to avoid possible compromises of the mail system by
		supplying bogus data.  Add configuration options for
		different set*gid() calls to reset saved gid.  Problem
		found by Michal Zalewski.
	PRIVACY: Prevent information leakage when sendmail has extra
		privileges by disabling debugging (command line -d flag)
		during queue runs and disabling ETRN when sendmail -bs is
		used.  Suggested by Michal Zalewski.
	Avoid memory corruption problems resulting from bogus .cf files.
		Problem found by Michal Zalewski.
	Set the ${server_addr} macro to name of mailer when doing LMTP
		delivery.  LMTP systems may offer SMTP Authentication or
		STARTTLS causing sendmail to use this macro in rulesets.
	If debugging is turned on (-d0.10) print not just the default
		values for configuration file and pid file but also the
		selected values.  Problem noted by Brad Chapman.
	Continue dealing with broken nameservers by ignoring SERVFAIL
		errors returned on T_AAAA (IPv6) lookups at delivery time
		if ResolverOptions=WorkAroundBrokenAAAA is set.  Previously
		this only applied to hostname canonification.  Problem
		noted by Bill Fenner of AT&T Research.
	Ignore comments in NIS host records when trying to find the
		canonical name for a host.
	When sendmail has extra privileges, limit mail submission command
		line flags (i.e., -G, -h, -F, etc.)  to mail submission
		operating modes (i.e., -bm, -bs, -bv, etc.).  Idea based on
		suggestion from Michal Zalewski.
	Portability:
		AIX: Use `oslevel` if available to determine OS version.
			`uname` does not given complete information.
			Problem noted by Keith Neufeld of the Cessna
			Aircraft Company.
		OpenUNIX: Use lockf() for LDA delivery (affects mail.local).
			Problem noticed by Boyd Lynn Gerber of ZENEX.
		Avoid compiler warnings by not using pointers to pass
			integers.  Problem noted by Todd C. Miller of
			Courtesan Consulting.
	CONFIG: Add restrictqrun to PrivacyOptions for the MSP to minimize
		problems with potential misconfigurations.
	CONFIG: Fix comment showing default value of MaxHopCount.  Problem
		noted by Greg Robinson of the Defence Science and
		Technology Organisation of Australia.
	CONFIG: dnsbl: If an argument specifies an error message in case
		of temporary lookup failures for DNS based blacklists
		then use it.
	LIBMILTER: Install mfdef.h, required by mfapi.h.  Problem noted by
		Richard A. Nelson of Debian.
	LIBMILTER: Add __P definition for OS that lack it.  Problem noted
		by Chris Adams from HiWAAY Informations Services.
	LIBSMDB: Fix a lock race condition that affects makemap, praliases,

8.12.0/8.12.0	2001/09/08
	*NOTICE*: The default installation of sendmail does not use
		set-user-ID root anymore.  You need to create a new user and
		a new group before installing sendmail (both called smmsp by
		default).  The installation process tries to install
		/etc/mail/submit.cf and creates /var/spool/clientmqueue by
		default.  Please see sendmail/SECURITY for details.
	SECURITY: Check for group and world writable forward and :include:
		files.  These checks can be turned off if absolutely
		necessary using the DontBlameSendmail option and the new
		flags:
			GroupWritableForwardFile
			WorldWritableForwardFile
			GroupWritableIncludeFile
			WorldWritableIncludeFile
		Problem noted by Slawek Zak of Politechnika Warszawska,
	SECURITY: Drop privileges when using address test mode.  Suggested
		by Michal Zalewski of the "Internet for Schools" project
		(IdS).
	Fixed problem of a global variable being used for a timeout jump
		point where the variable could become overused for more than
		one timeout concurrently.  This erroneous behavior resulted in
		a corrupted stack causing a core dump.  The timeout is now
		handled via libsm.  Problem noted by Michael Shapiro,
		John Beck, and Carl Smith of Sun Microsystems.
	If sendmail is set-group-ID then that group ID is used for permission
		checks (group ID of RunAsUser).  This allows use of a
		set-group-ID sendmail binary for initial message submission
		and no set-user-ID root sendmail is needed.  For details
		see sendmail/SECURITY.
	Log a warning if a non-trusted user changes the syslog label.
		Based on notice from Bryan Costales of SL3D, Inc.
	If sendmail is called for initial delivery, try to use submit.cf
		with a fallback of sendmail.cf as configuration file.  See
		sendmail/SECURITY.
	New configuration file option UseMSP to allow group writable queue
		files if the group is the same as that of a set-group-ID
		sendmail binary.  See sendmail/SECURITY.
	The .cf file is chosen based on the operation mode. For -bm (default),
		-bs, and -t it is submit.cf if it exists for all others it
		is sendmail.cf (to be backward compatible).  This selection
		can be changed by the new option -Ac or -Am (alternative .cf
		file: client or mta).  See sendmail/SECURITY.
	The SMTP server no longer forks on each MAIL command.  The ONEX
		command has been removed.
	Implement SMTP PIPELINING per RFC 2920.  It can be turned off
		at compile time or per host (ruleset).
	New option MailboxDatabase specifies the type of mailbox database
		used to look up local mail recipients; the default value
		is "pw", which means to use getpwnam().  New mailbox database
		types can be added by adding custom code to libsm/mbdb.c.
	Queue file names are now 15 characters long, rather than 14 characters
		long, to accomodate envelope splitting.  File systems with
		a 14 character file name length limit are no longer
		supported.
	Recipient list used for delivery now gets internally ordered by
		hostsignature (character string version of MX RR).  This orders
		recipients for the same MX RR's together meaning smaller
		portions of the list need to be scanned (instead of the whole
		list) each delivery() pass to determine piggybacking.  The
		significance of the change is better the larger the recipient
		list.  Hostsignature is now created during recipient list
		creation rather than just before delivery.
	Enhancements for more opportunistic piggybacking.  Previous
		piggybacking (called coincidental) extended to coattail
		piggybacking.  Rather than complete MX RR matching
		(coincidental) piggybacking is done if just the lowest value
		preference matches (coattail).
	If sendmail receives a temporary error on a RCPT TO: command, it will
		try other MX hosts if available.
	DefaultAuthInfo can contain a list of mechanisms to be used for
		outgoing (client-side) SMTP Authentication.
	New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable
		AUTH (overrides 'a' modifier in DaemonPortOptions).  Based
		on patch from Lyndon Nerenberg of Messaging Direct.
	Enable AUTH mechanism EXTERNAL if STARTTLS is used.
	A new ruleset authinfo can be used to return client side
		authentication information for AUTH instead of DefaultAuthInfo.
		Therefore the DefaultAuthInfo option is deprecated and will be
		removed in future versions.
	Accept any SMTP continuation code 3xy for AUTH even though RFC 2554
		requires 334.  Mercury 1.48 is a known offender.
	Add new option AuthMaxBits to limit the overall encryption strength
		for the security layer in SMTP AUTH (SASL).  See
		doc/op/op.me for details.
	Introduce new STARTTLS related macros {cn_issuer}, {cn_subject},
		{cert_md5} which hold the CN (common name) of the CA that
		signed the presented certificate, the CN and the MD5 hash
		of the presented certificate, respectively.
	New ruleset try_tls to decide whether to try (as client) STARTTLS.
	New ruleset srv_features to enable/disable certain features in the
		server per connection.  See doc/op/op.me for details.
	New ruleset tls_rcpt to decide whether to send e-mail to a particular
		recipient; useful to decide whether a conection is secure
		enough on a per recipient basis.
	New option TLSSrvOptions to modify some aspects of the server
		for STARTTLS.
	If no certificate has been requested, the macro {verify} has the
		value "NOT".
	New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off
		using/offering STARTTLS when delivering/receiving e-mail.
	Macro expand filenames/directories for certs and keys in the .cf file.
		Proposed by Neil Rickert of Northern Illinois University.
	Generate an ephemeral RSA key for a STARTTLS connection only if
		really required.  This change results in a noticable
		performance gains on most machines.  Moreover, if shared
		memory is in use, reuse the key several times.
	Add queue groups which can be used to group queue directories with
		the same behavior together.  See doc/op/op.me for details.
	If the new option FastSplit (defaults to one) has a value greater
		than zero, it suppresses the MX lookups on addresses when they
		are initially sorted which may result in faster envelope
		splitting.  If the mail is submitted directly from the
		command line, then the value also limits the number of
		processes to deliver the envelopes; if more envelopes are
		created they are only queued up and must be taken care of
		by a queue run.
	The check for 'enough disk space' now pays attention to which file
		system each queue directory resides in.
	All queue runners can be cleanly terminated via SIGTERM to parent.
	New option QueueFileMode for the default permissions of queue files.
	Add parallel queue runner code.  Allows multiple queue runners per work
		group (one or more queues in a multi-queue environment
		collected together) to process the same work list at the
		same time.
	Option MaxQueueChildren added to limit the number of concurrently
		active queue runner processes.
	New option MaxRunnersPerQueue to specify the maximum number of queue
		runners per queue group.
	Queue member selection by substring pattern matching now allows
		the pattern to be negated.  For -qI, -qR and -qS it is
		permissible for -q!I, -q!R and -q!S to mean remove members
		of the queue that match during processing.
	New -qp[time] option is similar to -qtime, except that instead of
		periodically forking a child to process the queue, a single
		child is forked for each queue that sleeps between queue
		runs.  A SIGHUP signal can be sent to restart this
		persistent queue runner.
	The SIGHUP signal now restarts a timed queue run process (i.e., a
		sendmail process which only runs the queue at an interval:
		sendmail -q15m).
	New option NiceQueueRun	to set the priority of queue runners.
		Proposed by Thom O'Connor.
	sendmail will run the queue(s) in the background when invoked with -q
		unless the new -qf option or -v is used.
	QueueSortOrder=Random sorts the queue randomly, which is useful if
		several queue runners are started by hand to avoid contention.
	QueueSortOrder=Modification sorts the queue by the modification time
		of the qf file (older entries first).
	Support Deliver By SMTP Service Extension (RFC 2852) which allows
		a client to specify an amount of time within which an e-mail
		should be delivered.  New option DeliverByMin added to set the
		minimum amount of time or disable the extension.
	Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are
		not allowed unless escaped or quoted.
	Add support for a generic DNS map.  Based on a patch contributed
		by Leif Johansson of Stockholm University, which was based on
		work by Assar Westerlund of Swedish Institute of Computer
		Science, Kista, and Johan Danielsson of Royal Institute of
		Technology, Stockholm, Sweden.
	MX records will be looked up for FallBackMXhost.  To use the old
		behavior (no MX lookups), put the name in square brackets.
		Proposed by Thom O'Connor.
	Use shared memory to store free space of filesystems that are used
		for queues, if shared memory is available and if a key is set
		via SharedMemoryKey.  This minimizes the number of system
		calls to check the available space.  See doc/op/op.me for
		details.
	If shared memory is compiled in the option -bP can be used to print
		the number of entries in the queue(s).
	Enable generic mail filter API (milter).  See libmilter/README
		and the usual documentation for details.
	Remove AutoRebuildAliases option, deprecated since 8.10.
	Remove '-U' (initial user submission) command line option as
		announced in 8.10.
	Remove support for non-standard SMTP command XUSR.  Use an MSA instead.
	New macro {addr_type} which contains whether the current address is
		an envelope sender or recipient address.  Suggested by
		Neil Rickert of Northern Illinois University.
	Two new options for host maps: -d (retransmission timeout),
		-r (number of retries).
	New option for LDAP maps: the -V<sep> allows you to specify a
		separator such that a lookup can return both an attribute
		and value separated by the given separator.
	Add new operators '%', '|', '&' (modulo, binary or, binary and)
		to map class arith.
	If DoubleBounceAddress expands to an empty string, ``double bounces''
		(errors that occur when sending an error message) are dropped.
	New DontBlameSendmail options GroupReadableSASLDBFile and
		GroupWritableSASLDBFile to relax requirements for sasldb files.
	New DontBlameSendmail options GroupReadableKeyFile to relax
		requirements for files containing secret keys.  This is
		necessary for the MSP if client authentification is used.
	Properly handle quoted filenames for class files (to allow for
		filenames with spaces).
	Honor the resolver option RES_NOALIASES when canonifying hostnames.
	Add macros to avoid the reuse of {if_addr} etc:
		{if_name_out}	hostname of interface of outgoing connection.
		{if_addr_out}	address of interface of outgoing connection.
		{if_family_out}	family of interface of outgoing connection.
		The latter two are only set if the interface does not belong
		to the loopback net.
	Add macro {nrcpts} which holds the number of (validated) recipients.
	DialDelay option applies only to mailers with flag 'Z'.  Patch from
		Juergen Georgi of RUS University of Stuttgart.
	New Timeout.lhlo,auth,starttls options to limit the time waiting for
		an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command.
	New Timeout.aconnect option to limit the overall waiting time for
		all connections for a single delivery attempt to succeed.
	Limit the rate recipients in the SMTP envelope are accepted once
		a threshold number of recipients has been rejected (option
		BadRcptThrottle).  From Gregory A Lundberg of the WU-FTPD
		Development Group.
	New option DelayLA to delay connections if the load averages
		exceeds the specified value.  The default of 0 does not
		change the previous behavior.  A value greater than 0
		will cause sendmail to sleep for one second on most
		SMTP commands and before accepting connections if that
		load average is exceeded.
	Use a dynamic (instead of fixed-size) buffer for the list of
		recipients that are sent during a connection to a mailer.
		This also introduces a new mailer field 'r' which defines
		the maximum number of recipients (defaults to 100).
		Based on patch by Motonori Nakamura of Kyoto University.
	Add new F=1 mailer flag to disable sending of null characters ('\0').
	Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead.
	The deprecated [TCP] builtin mailer pathname (P=) is gone.  Use [IPC]
		instead.
	IPC is no longer available as first mailer argument (A=) for [IPC]
		builtin mailer pathnames.  Use TCP instead.
	PH map code updated to use the new libphclient API instead of the
		old libqiapi library.  Contributed by Mark Roth of the
		University of Illinois at Urbana-Champaign.
	New option DirectSubmissionModifiers to define {daemon_flags}
		for direct (command line) submissions.
	New M=O modifier for DaemonPortOptions to ignore the socket in
		case of failures.  Based on patch by Jun-ichiro itojun
		Hagino of the KAME Project.
	Add Disposition-Notification-To: (RFC 2298) to the list of headers
		whose content is rewritten similar to Reply-To:.
		Proposed by Andrzej Filip.
	Use STARTTLS/AUTH=server/client for logging incoming/outgoing
		STARTTLS/AUTH connections; log incoming connections at level
		9 or higher.  Use AUTH/STARTTLS instead of SASL/TLS for SMTP
		AUTH/STARTTLS related logfile entries.
	Convert unprintable characters (and backslash) into octal or C format
		before logging.
	Log recipients if no message is transferred but QUIT/RSET is given
		(at LogLevel 9/10 or higher).
	Log discarded recipients at LogLevel 10 or higher.
	Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections
		in which most commands are rejected due to check_relay or
		TCP Wrappers if the host tries one of those commands anyway.
	Change logging format for cloned envelopes to be similar to that for
		DSNs ("old id: new id: clone").  Suggested by Ulrich Windl
		of the Universitat Regensburg.
	Added libsm, a C library of general purpose abstractions including
		assertions, tracing and debugging with named debug categories,
		exception handling, malloc debugging, resource pools,
		portability abstractions, and an extensible buffered I/O
		package.  It will at some point replace libsmutil.
		See libsm/index.html for details.
	Fixed most memory leaks in sendmail which were previously taken
		care of by fork() and exit().
	Use new sm_io*() functions in place of stdio calls.  Allows for
		more consistent portablity amongst different platforms
		new and old (from new libsm).
	Common I/O pkg means just one buffering method needed instead of two
		('bf_portable' and 'bf_torek' now just 'bf').
	Sfio no longer needed as SASL/TLS code uses sm_io*() API's.
	New possible value 'interactive' for SuperSafe which can be used
		together with DeliveryMode=interactive is to avoid some disk
		synchronizations calls.
	Add per-recipient status information to mailq -v output.
	T_ANY queries are no longer used by sendmail.
	When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS"
		too (see include/sm/cdefs.h for more info).
	sendmail -d now has general support for named debug categories.
		See libsm/debug.html and section 3.4 of doc/op/op.me
		for details.
	Eliminate the "postmaster warning" DSNs on address parsing errors
		such as unbalanced angle brackets or parentheses.  The DSNs
		generated by this condition were illegal (not RFC conform).
		Problem noted by Ulrich Windl of the Universitaet Regensburg.
	Do not issue a DSN if the ruleset localaddr resolves to the $#error
		mailer and the recipient has hence been rejected during the
		SMTP dialogue.  Problem reported by Larry Greenfield of CMU.
	Deal with a case of multiple deliveries on misconfigured systems
		that do not have postmaster defined.  If an email was sent
		from an address to which a DSN cannot be returned and
		in which at least one recipient address is non-deliverable,
		then that email had been delivered in each queue run.
		Problem reported by Matteo HCE Valsasna of Universita
		degli Studi dell'Insubria.
	The compilation options SMTP, DAEMON, and QUEUE have been removed,
		i.e., the corresponding code is always compiled in now.
	Log the command line in daemon/queue-run mode at LogLevel 10 and
		higher.  Suggested by Robert Harker of Harker Systems.
	New ResolverOptions setting: WorkAroundBrokenAAAA.  When
		attempting to canonify a hostname, some broken nameservers
		will return SERVFAIL (a temporary failure) on T_AAAA (IPv6)
		lookups.  If you want to excuse this behavior, use this new
		flag.  Suggested by Chris Foote of SE Network Access and
		Mark Roth of the University of Illinois at
		Urbana-Champaign.
	Free the memory allocated by getipnodeby{addr,name}().  Problem
		noted by Joy Latten of IBM.
	ConnectionRateThrottle limits the number of connections per second
		to each daemon individually, not the overall number of
		connections.
	Specifying only "ldap:" as an AliasFile specification will force
		sendmail to use a default alias schema as outlined in the
		``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of
		cf/README.
	Add a new syntax for the 'F' (file class) sendmail.cf command.  If
		the first character after the class name is not a '/' or a
		'|' and it contains an '@' (e.g., F{X}key@class:spec), the
		rest of the line will be parsed as a map lookup.  This
		allows classes to be filled via a map lookup.  See op.me
		for more syntax information.  Specifically, this can be
		used for commands such as VIRTUSER_DOMAIN_FILE() to read
		the list of domains via LDAP (see the ``USING LDAP FOR
		ALIASES, MAPS, and CLASSES'' section of cf/README for an
		example).
	The new macro ${sendmailMTACluster} determines the LDAP cluster for
		the default schema used in the above two items.
	Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a
		warning if a program being run from a mailer or file class
		(e.g., F|/path/to/prog) is in an unsafe directory path.
	Unless DontBlameSendmail=RunWritableProgram is set, log a warning
		if a program being run from a mailer or file class
		(e.g., F|/path/to/prog) is group or world writable.
	Loopback interfaces (e.g., "lo0") are now probed for class {w}
		hostnames.  Setting DontProbeInterfaces to "loopback"
		(without quotes) will disable this and return to the
		pre-8.12 behavior of only probing non-loopback interfaces.
		Suggested by Bryan Stansell of GNAC.
	In accordance with RFC 2821 section 4.1.4, accept multiple
		HELO/EHLO commands.
	Multiple ClientPortOptions settings are now allowed, one for each
		possible protocol family which may be used for outgoing
		connections.  Restrictions placed on one family only affect
		outgoing connections on that particular family.  Because of
		this change, the ${client_flags} macro is not set until the
		connection is established.  Based on patch from Motonori
		Nakamura of Kyoto University.
	PrivacyOptions=restrictexpand instructs sendmail to drop privileges
		when the -bv option is given by users who are neither root
		nor the TrustedUser so users can not read private aliases,
		forwards, or :include: files.  It also will override the -v
		(verbose) command line option.
	If the M=b modifier is set in DaemonPortOptions and the interface
		address can't be used for the outgoing connection, fall
		back to the settings in ClientPortOptions (if set).
		Problem noted by John Beck of Sun Microsystems.
	New named config file rule check_data for DATA command (input:
		number of recipients).  Based on patch from Mark Roth of
		the University of Illinois at Urbana-Champaign.
	Add support for ETRN queue selection per RFC 1985.  The queue group
		can be specified using the '#' option character.  For
		example, 'ETRN #queuegroup'.
	If an LDAP server times out or becomes unavailable, close the
		current connection and reopen to get to one of the fallback
		servers.  Patch from Paul Hilchey of the University of
		British Columbia.
	Make default error number on $#error messages 550 instead of 501
		because 501 is not allowed on all commands.
	The .cf file option UnsafeGroupWrites is deprecated, it should be
		replaced with the settings GroupWritableForwardFileSafe
		and GroupWritableIncludeFileSafe in DontBlameSendmail
		if required.
	The deprecated ldapx map class has been removed.  Use the ldap map
		class instead.
	Any IPv6 addresses used in configuration should be prefixed by the
		"IPv6:" tag to identify the address properly.  For example,
		if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to
		class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4].
	Change the $&{opMode} macro if the operation mode changes while the
		MTA is running.  For example, during a queue run.
	Add "use_inet6" as a new ResolverOptions flag to control the
		RES_USE_INET6 resolver option.  Based on patch from Rick
		Nelson of IBM.
	The maximum number of commands before the MTA slows down when too
		many "light weight" commands have been received are now
		configurable during compile time.  The current values and
		their defaults are:
		    MAXBADCOMMANDS	25	unknown commands
		    MAXNOOPCOMMANDS	20	NOOP, VERB, ONEX, XUSR
		    MAXHELOCOMMANDS	3	HELO, EHLO
		    MAXVRFYCOMMANDS	6	VRFY, EXPN
		    MAXETRNCOMMANDS	8	ETRN
		Setting a value to 0 disables the check.  Patch from Bryan
		Costales of SL3D, Inc.
	The header syntax H?${MyMacro}?X-My-Header: now not only checks if
		${MyMacro} is defined but also that it is not empty.
	Properly quote usernames with special characters if they are used
		in headers.  Problem noted by Kari Hurtta of the Finnish
		Meteorological Institute.
	Be sure to include the proper Final-Recipient: DSN header in bounce
		messages for messages for mailing list expanded addresses
		which are not delivered on the initial attempt.
	Do not treat errors as sticky when doing delivery via LMTP after
		the final dot has been sent to avoid affecting future
		deliveries.  Problem reported by Larry Greenfield of CMU.
	New compile time flag REQUIRES_DIR_FSYNC which turns on support for
		file systems that require to call fsync() for a directory
		if the meta-data in it has been changed.  This should be
		set at least for ReiserFS; it is enabled by default for Linux.
		See sendmail/README for further information.
	Avoid file locking deadlock when updating the statistics file if
		sendmail is signaled to terminate.  Problem noted by
		Christophe Wolfhugel of France Telecom.
	Set the $c macro (hop count) as it is being set instead of when the
		envelope is initialized.  Problem noted by Kari Hurtta of
		the Finnish Meteorological Institute.
	Properly count recipients for DeliveryMode defer and queue.  Fix
		from Peter A. Friend of EarthLink.
	Treat invalid hesiod lookups as permanent errors instead of
		temporary errors.  Problem noted by Russell McOrmond of
		flora.ca.
	Portability:
		Remove support for AIX 2, which supports only 14 character
			filenames and is outdated anyway.  Suggested by
			Valdis Kletnieks of Virginia Tech.
		Change several settings for Irix 6: remove confSBINDIR,
			i.e., use default /usr/sbin, change owner/group
			of man pages and user-executable to root/sys, set
			optimization limit to 0 (unlimited).  Based on patch
			from Ayamura Kikuchi, M.D, and proposal from Kari
			Hurtta of the Finnish Meteorological Institute.
		Do not assume LDAP support is installed by default under
			Solaris 8 and later.
		Add support for OpenUNIX.
	CONFIG: Increment version number of config file to 10.
	CONFIG: Add an install target and a README file in cf/cf.
	CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc.
	CONFIG: Reject empty recipient addresses (in check_rcpt).
	CONFIG: The access map uses an option of -T<TMPF> to deal with
		temporary lookup failures.
	CONFIG: New value for access map: SKIP, which causes the default
		action to be taken by aborting the search for domain names
		or IP nets.
	CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or
		relay address as long as the other part allows the email
		to get through.
	CONFIG: Entries for virtusertable can make use of a third parameter
		"%3" which contains "+detail" of a wildcard match, i.e., an
		entry like user+*@domain.  This allows handling of details by
		using %1%3 as the RHS.  Additionally, a "+" wildcard has been
		introduced to match only non-empty details of addresses.
	CONFIG: Numbers for rulesets used by MAILERs have been removed
		and hence there is no required order within the MAILER
		section anymore except for MAILER(`uucp') which must come
		after MAILER(`smtp') if uucp-dom and uucp-uudom are used.
	CONFIG: Hosts listed in the generics domain class {G}
		(GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated
		as canonical.  Suggested by Per Hedeland of Ericsson.
	CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup
		in the access map which returns OK or RELAY actually
		terminates check_* ruleset checking.
	CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset
		tls_rcpt, see cf/README for details.
	CONFIG: Change format of Received: header line which reveals whether
		STARTTLS has been used to "(version=${tls_version}
		cipher=${cipher} bits=${cipher_bits} verify=${verify})".
	CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks')
		options friends/haters instead of "To:" and enable
		specification of whole domains instead of just users.
		Notice: this change is not backward compatible.
		Suggested by Chris Adams from HiWAAY Informations Services.
	CONFIG: Allow for local extensions for most new rulesets, see
		cf/README for details.
	CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in
		the access map.  Proposed by Randall Winchester of the
		University of Maryland.
	CONFIG: New FEATURE(`local_no_masquerade') to avoid masquerading for
		the local mailer.  Proposed by Ingo Brueckl of Wupper Online.
	CONFIG: confRELAY_MSG/confREJECT_MSG can override the default
		messages for an unauthorized relaying attempt/for access
		map entries with RHS REJECT, respectively.
	CONFIG: FEATURE(`always_add_domain') takes an optional argument
		to specify another domain to be added instead of the local one.
		Suggested by Richard H. Gumpertz of Computer Problem
		Solving.
	CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific
		options, see doc/op/op.me for details.
	CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for
		the security layer in SMTP AUTH (SASL).
	CONFIG: If Local_localaddr resolves to $#ok, localaddr is terminated
		immediately.
	CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which
		allows checking of the return values of the DNS lookups.
		See cf/README for details.
	CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for
		temporary lookup failures.
	CONFIG: New option confDELIVER_BY_MIN to specify minimum time for
		Deliver By (RFC 2852) or to turn off the extension.
	CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared
		memory use.
	CONFIG: New FEATURE(`compat_check') to look up a key consisting
		of the sender and the recipient address delimited by the
		string "<@>", e.g., sender@sdomain<@>recipient@rdomain,
		in the access map.  Based on code contributed by Mathias
		Koerber of Singapore Telecommunications Ltd.
	CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user
		file.  Suggested by John Beck of Sun Microsystems.
	CONFIG: Don't use MAILER-DAEMON for error messages delivered
		via LMTP.  Problem reported by Larry Greenfield of CMU.
	CONFIG: New FEATURE(`preserve_luser_host') to preserve the name of
		the recipient host if LUSER_RELAY is used.
	CONFIG: New FEATURE(`preserve_local_plus_detail') to preserve the
		+detail portion of the address when passing address to
		local delivery agent.  Disables alias and .forward +detail
		stripping.  Only use if LDA supports this.
	CONFIG: Removed deprecated FEATURE(`rbl').
	CONFIG: Add LDAPROUTE_EQUIVALENT() and LDAPROUTE_EQUIVALENT_FILE()
		which allow you to specify 'equivalent' hosts for LDAP
		Routing lookups.  Equivalent hostnames are replaced by the
		masquerade domain name for lookups.  See cf/README for
		additional details.
	CONFIG: Add a fourth argument to FEATURE(`ldap_routing') which
		instructs the rulesets on what to do if the address being
		looked up has +detail information.  See cf/README for more
		information.
	CONFIG: When chosing a new destination via LDAP Routing, also look
		up the new routing address/host in the mailertable.  Based
		on patch from Don Badrak of the United States Census Bureau.
	CONFIG: Do not reject the SMTP Mail from: command if LDAP Routing
		is in use and the bounce option is enabled.  Only reject
		recipients as user unknown.
	CONFIG: Provide LDAP support for the remaining database map
		features.  See the ``USING LDAP FOR ALIASES AND MAPS''
		section of cf/README for more information.
	CONFIG: Add confLDAP_CLUSTER which defines the ${sendmailMTACluster}
		macro used for LDAP searches as described above in ``USING
		LDAP FOR ALIASES, MAPS, AND CLASSES''.
	CONFIG: confCLIENT_OPTIONS has been replaced by CLIENT_OPTIONS(),
		which takes the options as argument and can be used
		multiple times; see cf/README for details.
	CONFIG: Add configuration macros for new options:
		confBAD_RCPT_THROTTLE		BadRcptThrottle
		confDIRECT_SUBMISSION_MODIFIERS	DirectSubmissionModifiers
		confMAILBOX_DATABASE		MailboxDatabase
		confMAX_QUEUE_CHILDREN		MaxQueueChildren
		confMAX_RUNNERS_PER_QUEUE	MaxRunnersPerQueue
		confNICE_QUEUE_RUN		NiceQueueRun
		confQUEUE_FILE_MODE		QueueFileMode
		confFAST_SPLIT			FastSplit
		confTLS_SRV_OPTIONS		TLSSrvOptions
		See above (and related documentation) for further information.
	CONFIG: Add configuration variables for new timeout options:
		confTO_ACONNECT		Timeout.aconnect
		confTO_AUTH		Timeout.auth
		confTO_LHLO		Timeout.lhlo
		confTO_STARTTLS		Timeout.starttls
	CONFIG: Add configuration macros for mail filter API:
		confINPUT_MAIL_FILTERS		InputMailFilters
		confMILTER_LOG_LEVEL		Milter.LogLevel
		confMILTER_MACROS_CONNECT	Milter.macros.connect
		confMILTER_MACROS_HELO		Milter.macros.helo
		confMILTER_MACROS_ENVFROM	Milter.macros.envfrom
		confMILTER_MACROS_ENVRCPT	Milter.macros.envrcpt
		Mail filters can be defined via INPUT_MAIL_FILTER() and
		MAIL_FILTER().  See libmilter/README, cf/README, and
		doc/op/op.me for details.
	CONFIG: Add support for accepting temporarily unresolvable domains.
		See cf/README for details.  Based on patch by Motonori
		Nakamura of Kyoto University.
	CONFIG: confDEQUOTE_OPTS can be used to specify options for the
		dequote map.
	CONFIG: New macro QUEUE_GROUP() to define queue groups.
	CONFIG: New FEATURE(`queuegroup') to select a queue group based
		on the full e-mail address or the domain of the recipient.
	CONFIG: Any IPv6 addresses used in configuration should be prefixed
		by the "IPv6:" tag to identify the address properly.  For
		example, if you want to use the IPv6 address
		2002:c0a8:51d2::23f4 in the access database, you would need
		to use IPv6:2002:c0a8:51d2::23f4 on the left hand side.
		This affects the access database as well as the
		relay-domains and local-host-names files.
	CONFIG: OSTYPE(aux) has been renamed to OSTYPE(a-ux).
	CONFIG: Avoid expansion of m4 keywords in SMART_HOST.
	CONFIG: Add MASQUERADE_EXCEPTION_FILE() for reading masquerading
		exceptions from a file.  Suggested by Trey Breckenridge of
		Mississippi State University.
	CONFIG: Add LOCAL_USER_FILE() for reading local users
		(LOCAL_USER() -- $={L}) entries from a file.
	CONTRIB: dnsblaccess.m4 is a further enhanced version of enhdnsbl.m4
		which allows to lookup error codes in the access map.
		Contributed by Neil Rickert of Northern Illinois University.
	DEVTOOLS: Add new options for installation of include and library
		files: confINCGRP, confINCMODE, confINCOWN, confLIBGRP,
		confLIBMODE, confLIBOWN.
	DEVTOOLS: Add new option confDONT_INSTALL_CATMAN to turn off
		installation of the the formatted man pages on operating
		systems which don't include cat directories.
	EDITMAP: New program for editing maps as supplement to makemap.
	MAIL.LOCAL: Mail.local now uses the libsm mbdb package to look up
		local mail recipients.  New option -D mbdb specifies the
		mailbox database type.
	MAIL.LOCAL: New option "-h filename" which instructs mail.local to
		deliver the mail to the named file in the user's home
		directory instead of the system mail spool area.  Based on
		patch from Doug Hardie of the Los Angeles Free-Net.
	MAILSTATS: New command line option -P which acts the same as -p but
		doesn't truncate the statistics file.
	MAKEMAP: Add new option -t to specify a different delimiter
		instead of white space.
	RMAIL: Invoke sendmail with '-G' to indicate this is a gateway
		submission.  Problem noted by Kari Hurtta of the Finnish
		Meteorological Institute.
	SMRSH: Use the vendor supplied directory on FreeBSD 3.3 and later.
	VACATION: Change Auto-Submitted: header value from auto-generated to
		auto-replied.  From Kenneth Murchison of Oceana Matrix Ltd.
	VACATION: New option -d to send error/debug messages to stdout
		instead of syslog.
	VACATION: New option -U which prevents the attempt to lookup login
		in the password file.  The -f and -m options must be used
		to specify the database and message file since there is no
		home directory for the default settings for these options.
	VACATION: Vacation now uses the libsm mbdb package to look up
		local mail recipients; it reads the MailboxDatabase option
		from the sendmail.cf file.  New option -C cffile which
		specifies the path of the sendmail.cf file.

8.11.7/8.11.7	2003/03/29
	SECURITY: Fix a remote buffer overflow in header parsing by
		dropping sender and recipient header comments if the
		comments are too long.  Problem noted by Mark Dowd
		of ISS X-Force.
	SECURITY: Fix a buffer overflow in address parsing due to
		a char to int conversion problem which is potentially
		remotely exploitable.  Problem found by Michal Zalewski.
		Note: an MTA that is not patched might be vulnerable to
		data that it receives from untrusted sources, which
		includes DNS.
	To provide partial protection to internal, unpatched sendmail MTAs,
		8.11.7 changes by default (char)0xff to (char)0x7f in
		headers etc.  To turn off this conversion compile with
		-DALLOW_255 or use the command line option -d82.101.
	To provide partial protection for internal, unpatched MTAs that may be
		performing 7->8 or 8->7 bit MIME conversions, the default
		for MaxMimeHeaderLength has been changed to 2048/1024.
		Note: this does have a performance impact, and it only
		protects against frontal attacks from the outside.
		To disable the checks and return to pre-8.11.7 defaults,
		set MaxMimeHeaderLength to 0/0.
	Properly clean up macros to avoid persistence of session data
		across various connections.  This could cause session
		oriented restrictions, e.g., STARTTLS requirements,
		to erroneously allow a connection.  Problem noted
		by Tim Maletic of Priority Health.

	SECURITY: Fix a possible memory access violation when specifying
		out-of-bounds debug parameters.  Problem detected by
		Cade Cairns of SecurityFocus.
	Avoid leaking recipient information in unrelated DSNs.  This could

	When commands were being rejected due to check_relay or TCP
		Wrappers, the ETRN command was not giving a response.
	Incoming IPv4 connections on a Family=inet6 daemon (using
		IPv4-mapped addresses) were incorrectly labeled as "may be

		University at Albany.
	Mark closed file descriptors properly to avoid reuse. Problem
		noted by Jeff Bronson of J.D. Bronson, Inc.
	Setting Timeout options on the command line will also override
		their sub-suboptions in the .cf file, e.g., -O

		to 2 days.  Problem noted by Roger B.A. Klorese.
	Portability:
		BSD/OS has a broken setreuid() implementation.  Problem
			noted by Vernon Schryver of Rhyolite Software.

8.11.4/8.11.4	2001/05/28
	Clean up signal handling routines to reduce the chances of heap
		corruption and other potential race conditions.
		Terminating and restarting the daemon may not be
		instantaneous due to this change.  Also, non-root users can
		no longer send out-of-band signals.  Problem reported by
		Michal Zalewski of BindView.
	If LogLevel is greater than 9 and SASL fails to negotiate an
		encryption layer, avoid core dump logging the encryption
		strength.  Problem noted by Miroslav Zubcic of Crol.
	If a server offers "AUTH=" and "AUTH " and the list of mechanisms is
		different in those two lines, sendmail might not have
		recognized (and used) all of the offered mechanisms.
	Fix an IP address lookup problem on Solaris 2.0 - 2.3.  Patch
		from Kenji Miyake.
	This time, really don't use the .. directory when expanding

	If a process is interrupted while closing a map, don't try to close
		the same map again while exiting.
	Allow local mailers (F=l) to contact remote hosts (e.g., via
		LMTP).  Problem noted by Norbert Klasen of the University
		of Tuebingen.
	If Timeout.QueueReturn was set to a value less the time it took
		to write a new queue file (e.g., 0 seconds), the bounce
		message would be lost.  Problem noted by Lorraine L Goff of
		Oklahoma State University.
	Pass map argument vector into map rewriting engine for the regex
		and prog map types.  Problem noted by Stephen Gildea of
		InTouch Systems, Inc.
	When closing an LDAP map due to a temporary error, close all of the

8.11.3/8.11.3	2001/02/27
	Prevent a segmentation fault when a bogus value was used in the
		LDAPDefaultSpec option's -r, -s, or -M flags and if a bogus
		option was used.  Problem noted by Allan E Johannesen of

		Problem detected by Jan Krueger of digitalanswers
		communications consulting gmbh.
	Additional IPv6 check for unspecified addresses.  Patch from
		Jun-ichiro itojun Hagino of the KAME Project.
	Do not ignore the ClientPortOptions setting if DaemonPortOptions
		Modifier=b (bind to same interface) is set and the
		connection came in from the command line.
	Do not bind to the loopback address if DaemonPortOptions
		Modifier=b (bind to same interface) is set.  Patch from
		John Beck of Sun Microsystems.
	Properly deal with open failures on non-optional maps used in
		check_* rulesets by returning a temporary failure.
	Buffered file I/O files were not being properly fsync'ed to disk
		when they were committed.
	Properly encode '=' for the AUTH= parameter of the MAIL command.
		Problem noted by Hadmut Danisch.
	Under certain circumstances the macro {server_name} could be set
		to the wrong hostname (of a previous connection), which may
		cause some rulesets to return wrong results.  This would
		usually cause mail to be queued up and delivered later on.
	Ignore F=z (LMTP) mailer flag if $u is given in the mailer A=
		equate.  Problem noted by Motonori Nakamura of Kyoto
		University.
	Work around broken accept() implementations which only partially
		fill in the peer address if the socket is closed before
		accept() completes.
	Return an SMTP "421" temporary failure if the data file can't be
		opened where the "354" reply would normally be given.
	Prevent a CPU loop in trying to expand a macro which doesn't exist
		in a queue run.  Problem noted by Gordon Lack of Glaxo
		Wellcome.
	If delivering via a program and that program exits with EX_TEMPFAIL,
		note that fact for the mailq display instead of just showing
		"Deferred".  Problem noted by Motonori Nakamura of Kyoto
		University.
	If doing canonification via /etc/hosts, try both the fully
		qualified hostname as well as the first portion of the
		hostname.  Problem noted by David Bremner of the
		University of New Brunswick.

		side has sent the final DATA termination dot.  Problem
		noted by Allan E Johannesen of Worcester Polytechnic
		Institute.
	MAIL.LOCAL: If LMTP mode is set, give a temporary error if users
		are also specified on the command line.  Patch from
		Motonori Nakamura of Kyoto University.
	PRALIASES: Skip over AliasFile specifications which aren't based on
		database files (i.e., only show dbm, hash, and btree).
	Renamed Files:
		devtools/OS/OSF1.V5.0 => devtools/OS/OSF1.V5.x

8.11.2/8.11.2	2000/12/29
	Prevent a segmentation fault when trying to set a class in
		address test mode due to a negative array index.  Audit
		other array indexing.  This bug is not believed to be
		exploitable.  Noted by Michal Zalewski of the "Internet for
		Schools" project (IdS).
	Add an FFR (for future release) to drop privileges when using
		address test mode.  This will be turned on in 8.12. It can
		be enabled by compiling with:
		APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_TESTMODE_DROP_PRIVS')
		in your devtools/Site/site.config.m4 file.  Suggested by
		Michal Zalewski of the "Internet for Schools" project (IdS).
	Fix potential problem with Cyrus-SASL security layer which may have
		caused I/O errors, especially for mechanism DIGEST-MD5.
	When QueueSortOrder was set to host, sendmail might not read
		enough of the queue file to determine the host, making the
		sort sub-optimal.  Problem noted by Jeff Earickson of
		Colby College.
	Don't issue DSNs for addresses which use the NOTIFY parameter (per
		RFC 1891) but don't have FAILURE as value.
	Initialize Cyrus-SASL library before the SMTP daemon is started.
		This implies that every change to SASL related files requires
		a restart of the daemon, e.g., Sendmail.conf, new SASL
		mechanisms (in form of shared libraries).
	Properly set the STARTTLS related macros during a queue run for
		a cached connection.  Bug reported by Michael Kellen of
		NxNetworks, Inc.
	Log the server name in relay= for ruleset tls_server instead of the
		client name.
	Include original length of bad field/header when reporting
		MaxMimeHeaderLength problems.  Requested by Ulrich Windl of
		the Universitat Regensburg.
	Fix delivery to set-user-ID files that are expanded from aliases in
		DeliveryMode queue.  Problem noted by Ric Anderson of the
		University of Arizona.
	Fix LDAP map -m (match only) flag.  Problem noted by Jeff Giuliano
		of Collective Technologies.
	Avoid using a negative argument for sleep() calls when delaying answers
		to EXPN/VRFY commands on systems which respond very slowly.
		Problem noted by Mikolaj J. Habryn of Optus Internet
		Engineering.
	Make sure the F=u flag is set in the default prog mailer

		Kletnieks of Virginia Tech.
	When delivering to a file directly from an alias, do not call
		initgroups(); instead use the DefaultUser group information.
		Problem noted by Marc Schaefer of ALPHANET NF.
	RunAsUser now overrides the ownership of the control socket, if
		created.  Otherwise, sendmail can not remove it upon
		close.  Problem noted by Werner Wiethege.
	Fix ConnectionRateThrottle counting as the option is the number of
		overall connections, not the number of connections per
		socket.  A future version may change this to per socket
		counting.
	Portability:
		Clean up libsmdb so it functions properly on platforms
			where sizeof(u_int32_t) != sizeof(size_t).  Problem

		patch by Motonori Nakamura of Kyoto University.
	CONFIG: New OSTYPE(`aix5') contributed by Valdis Kletnieks of
		Virginia Tech.
	CONFIG: Pass the illegal header form <list:;> through untouched
		instead of making it worse.  Problem noted by Motonori
		Nakamura of Kyoto University.
	CONTRIB: Added buildvirtuser (see `perldoc contrib/buildvirtuser`).
	CONTRIB: qtool.pl: An empty queue is not an error.  Problem noted
		by Jan Krueger of digitalanswers communications consulting
		gmbh.
	CONTRIB: domainmap.m4: Handle domains with '-' in them.  From Mark
		Roth of the University of Illinois at Urbana-Champaign.
	DEVTOOLS: Change the internal devtools OS, REL, and ARCH m4
		variables into bldOS, bldREL, and bldARCH to prevent
		namespace collisions.  Problem noted by Motonori Nakamura
		of Kyoto University.
	RMAIL: Undo the 8.11.1 change to use -G when calling sendmail.  It
		causes some changes in behavior and may break rmail for
		installations where sendmail is actually a wrapper to
		another MTA.  The change will re-appear in a future
		version.
	SMRSH: Use the vendor supplied directory on HPUX 10.X, HPUX 11.X,
		and SunOS 5.8.  Requested by Jeff A. Earickson of Colby
		College and John Beck of Sun Microsystems.
	VACATION: Fix pattern matching for addresses to ignore.

8.11.1/8.11.1	2000/09/27
	Fix SMTP EXPN command output if the address expands to a single
		name.  Fix from John Beck of Sun Microsystems.
	Don't try STARTTLS in the client if the PRNG has not been properly
		seeded.  This problem only occurs on systems without
		/dev/urandom.  Problem detected by Jan Krueger of
		digitalanswers communications consulting gmbh and
		Neil Rickert of Northern Illinois University.
	Don't use the . and .. directories when expanding QueueDirectory
		wildcards.
	Do not try to cache LDAP connections across processes as a parent
		process may close the connection before the child process
		has completed.  Problem noted by Lai Yiu Fai of the Hong
		Kong University of Science and Technology and Wolfgang
		Hottgenroth of UUNET.
	Use Timeout.fileopen to limit the amount of time spent trying to
		read the LDAP secret from a file.

		attempt completes.  Problem noted by Max France of AlphaNet.
		Fix from Neil Rickert of Northern Illinois University.
	Deal correctly with MaxMessageSize restriction if message size is
		greater than 2^31.  Problem noted by Tim "Darth Dice" Bosserman
		of EarthLink.
	Turn off queue checkpointing if CheckpointInterval is set to zero.
	Treat an empty home directory (from getpw*() or $HOME) as
		non-existent instead of treating it as /.  Problem noted by
		Todd C. Miller of Courtesan Consulting.
	Don't drop duplicate headers when reading a queued item.  Problem
		noted by Motonori Nakamura of Kyoto University.
	Avoid bogus error text when logging the savemail panic "cannot
		save rejected email anywhere".  Problem noted by Marc G.
		Fournier of Acadia University.
	If an LDAP search fails because the LDAP server went down, close
		the map so subsequent searches reopen the map.  If there are
		multiple LDAP servers, the down server will be skipped and
		one of the others may be able to take over.
	Set the ${load_avg} macro to the current load average, not the
		previous load average query result.
	If a non-optional map used in a check_* ruleset can't be opened,
		return a temporary failure to the remote SMTP client
		instead of ignoring the map.  Problem noted by Allan E
		Johannesen of Worcester Polytechnic Institute.
	Avoid a race condition when queuing up split envelopes by saving
		the split envelopes before the original envelope.
	Fix a bug in the PH_MAP code which caused mail to bounce instead of
		defer if the PH server could not be contacted.  From Mark
		Roth of the University of Illinois at Urbana-Champaign.
	Prevent QueueSortOrder=Filename from interfering with -qR, -qS, and
		ETRN.  Problem noted by Erik R. Leo of SoVerNet.
	Change error code for unrecognized parameters to the SMTP MAIL and
		RCPT commands from 501 to 555 per RFC 1869.  Problem
		reported to Postfix by Robert Norris of Monash University.
	Prevent overwriting the argument of -B on certain OS.  Problem
		noted by Matteo Gelosa of I.NET S.p.A.
	Use the proper routine for freeing memory with Netscape's LDAP
		client libraries.  Patch from Paul Hilchey of the
		University of British Columbia.
	Portability:
		Move the NETINET6 define to devtools/OS/SunOS.5.{8,9}
			instead of defining it in conf.h so users can
			override the setting.  Suggested by
			Henrik Nordstrom of Ericsson.
		On HP-UX 10.X and 11.X, use /usr/sbin/sendmail instead of
			/usr/lib/sendmail for rmail and vacation.  From
			Jeff A. Earickson of Colby College.
		On HP-UX 11.X, use /usr/sbin instead of /usr/libexec (which
			does not exist).  From Jeff A. Earickson of Colby
			College.
		Avoid using the UCB subsystem on NCR MP-RAS 3.x.  From
			Tom Moore of NCR.
		NeXT 3.X and 4.X installs man pages in /usr/man.  From
			Hisanori Gogota of NTT/InterCommunicationCenter.
		Solaris 8 and later include /var/run.  The default PID file
			location is now /var/run/sendmail.pid.  From John
			Beck of Sun Microsystems.
		SFIO includes snprintf() for those operating systems
			which do not.  From Todd C. Miller of Courtesan
			Consulting.
	CONFIG: Use the result of _CERT_REGEX_SUBJECT_ not {cert_subject}.
		Problem noted by Kaspar Brand of futureLab AG.
	CONFIG: Change 553 SMTP reply code to 501 to avoid problems with
		errors in the MAIL address.
	CONFIG: Fix FEATURE(nouucp) usage in example .mc files.  Problem
		noted by Ron Jarrell of Virginia Tech.
	CONFIG: Add support for Solaris 8 (and later) as OSTYPE(solaris8).
		Contributed by John Beck of Sun Microsystems.
	CONFIG: Set confFROM_HEADER such that the mail hub can possibly add
		GECOS information for an address.  This more closely
		matches pre-8.10 nullclient behavior.  From Per Hedeland of
		Ericsson.
	CONFIG: Fix MODIFY_MAILER_FLAGS(): apply the flag modifications for
		SMTP to all *smtp* mailers and those for RELAY to the relay
		mailer as described in cf/README.
	MAIL.LOCAL: Open the mailbox as the recipient not root so quotas
		are obeyed.  Problem noted by Damian Kuczynski of NIK.
	MAKEMAP: Do not change a map's owner to the TrustedUser if using
		makemap to 'unmake' the map.
	RMAIL: Avoid overflowing the list of recipients being passed to
		sendmail.
	RMAIL: Invoke sendmail with '-G' to indicate this is a gateway
		submission.  Problem noted by Kari Hurtta of the Finnish
		Meteorological Institute.
	VACATION: Read the complete message to avoid "broken pipe" signals.
	VACATION: Do not cut off vacation.msg files which have a single
		dot as the only character on the line.
	New Files:
		cf/ostype/solaris8.m4

8.11.0/8.11.0	2000/07/19
	SECURITY: If sendmail is installed as a non-root set-user-ID binary
		(not the normal case), some operating systems will still
		keep a saved-uid of the effective-uid when sendmail tries
		to drop all of its privileges.  If sendmail needs to drop
		these privileges and the operating system doesn't set the
		saved-uid as well, exit with an error.  Problem noted by
		Kari Hurtta of the Finnish Meteorological Institute.
	SECURITY: sendmail depends on snprintf() NUL terminating the string
		it populates.  It is possible that some broken
		implementations of snprintf() exist that do not do this.
		Systems in this category should compile with
		-DSNPRINTF_IS_BROKEN=1.  Use test/t_snprintf.c to test your
		system and report broken implementations to
		sendmail-bugs@sendmail.org and your OS vendor.  Problem
		noted by Slawomir Piotrowski of TELSAT GP.
	Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS).
		Implementation influenced by the example programs of
		OpenSSL and the work of Lutz Jaenicke of TU Cottbus.
	Add new STARTTLS related options CACERTPath, CACERTFile,
		ClientCertFile, ClientKeyFile, DHParameters, RandFile,
		ServerCertFile, and ServerKeyFile.  These are documented in
		cf/README and doc/op/op.me.
	New STARTTLS related macros: ${cert_issuer}, ${cert_subject},
		${tls_version}, ${cipher}, ${cipher_bits}, ${verify},
		${server_name}, and ${server_addr}.  These are documented
		in cf/README and doc/op/op.me.
	Add support for the Entropy Gathering Daemon (EGD) for better
		random data.
	New DontBlameSendmail option InsufficientEntropy for systems which
		don't properly seed the PRNG for OpenSSL but want to
		try to use STARTTLS despite the security problems.
	Support the security layer in SMTP AUTH for mechanisms which
		support encryption.  Based on code contributed by Tim
		Martin of CMU.
	Add new macro ${auth_ssf} to reflect the SMTP AUTH security
		strength factor.
	LDAP's -1 (single match only) flag was not honored if the -z
		(delimiter) flag was not given.  Problem noted by ST Wong of
		the Chinese University of Hong Kong.  Fix from Mark Adamson
		of CMU.
	Add more protection from accidentally tripping OpenLDAP 1.X's
		ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute().
		Suggested by Kurt Zeilenga of OpenLDAP.
	Fix the default family selection for DaemonPortOptions.  As
		documented, unless a family is specified in a
		DaemonPortOptions option, "inet" is the default.  It is
		also the default if no DaemonPortOptions value is set.
		Therefore, IPv6 users should configure additional sockets
		by adding DaemonPortOptions settings with Family=inet6 if
		they wish to also listen on IPv6 interfaces.  Problem noted
		by Jun-ichiro itojun Hagino of the KAME Project.
	Set ${if_family} when setting ${if_addr} and ${if_name} to reflect
		the interface information for an outgoing connection.
		Not doing so was creating a mismatch between the socket
		family and address used in subsequent connections if the
		M=b modifier was set in DaemonPortOptions.  Problem noted
		by John Beck of Sun Microsystems.
	If DaemonPortOptions modifier M=b is used, determine the socket
		family based on the IP address.  ${if_family} is no longer
		persistent (i.e., saved in qf files).  Patch from John Beck
		of Sun Microsystems.
	sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family}
		macros for both the incoming interface address/family and
		the outgoing interface address/family.  In order for M=b
		modifier in DaemonPortOptions to work properly, preserve
		the incoming information in the queue file for later
		delivery attempts.
	Use SMTP error code and enhanced status code from check_relay in
		responses to commands.  Problem noted by Jeff Wasilko of
		smoe.org.
	Add more vigilance in checking for putc() errors on output streams
		to protect from a bug in Solaris 2.6's putc().  Problem
		noted by Graeme Hewson of Oracle.
	The LDAP map -n option (return attribute names only) wasn't working.
		Problem noted by Ajay Matia.
	Under certain circumstances, an address could be listed as deferred
		but would be bounced back to the sender as failed to be
		delivered when it really should have been queued.  Problem
		noted by Allan E Johannesen of Worcester Polytechnic Institute.
	Prevent a segmentation fault in a child SMTP process from getting
		the SMTP transaction out of sync.  Problem noted by Per
		Hedeland of Ericsson.
	Turn off RES_DEBUG if SFIO is defined unless SFIO_STDIO_COMPAT
		is defined to avoid a core dump due to incompatibilities
		between sfio and stdio.  Problem noted by Neil Rickert
		of Northern Illinois University.
	Don't log useless envelope ID on initial connection log.  Problem
		noted by Kari Hurtta of the Finnish Meteorological Institute.
	Convert the free disk space shown in a control socket status query
		to kilobyte units.
	If TryNullMXList is True and there is a temporary DNS failure
		looking up the hostname, requeue the message for a later
		attempt.  Problem noted by Ari Heikkinen of Pohjois-Savo
		Polytechnic.
	Under the proper circumstances, failed connections would be recorded
		as "Bad file number" instead of "Connection failed" in the
		queue file and persistent host status.  Problem noted by
		Graeme Hewson of Oracle.
	Avoid getting into an endless loop if a non-hoststat directory exists
		within the hoststatus directory (e.g., lost+found).
		Patch from Valdis Kletnieks of Virginia Tech.
	Make sure Timeout.queuereturn=now returns a bounce message to the
		sender.  Problem noted by Per Hedeland of Ericsson.
	If a message data file can't be opened at delivery time, panic and
		abort the attempt instead of delivering a message that
		states "<<< No Message Collected >>>".
	Fixup the GID checking code from 8.10.2 as it was overly
		restrictive.  Problem noted by Mark G. Thomas of Mark
		G. Thomas Consulting.
	Preserve source port number instead of replacing it with the ident
		port number (113).
	Document the queue status characters in the mailq man page.
		Suggested by Ulrich Windl of the Universitat Regensburg.
	Process queued items in which none of the recipient addresses have
		host portions (or there are no recipients).  Problem noted
		by Valdis Kletnieks of Virginia Tech.
	If a cached LDAP connection is used for multiple maps, make sure
		only the first to open the connection is allowed to close
		it so a later map close doesn't break the connection for
		other maps.  Problem noted by Wolfgang Hottgenroth of UUNET.
	Netscape's LDAP libraries do not support Kerberos V4
		authentication.  Patch from Rainer Schoepf of the
		University of Mainz.
	Provide workaround for inconsistent handling of data passed
		via callbacks to Cyrus SASL prior to version 1.5.23.
	Mention ENHANCEDSTATUSCODES in the SMTP HELP helpfile.  Omission
		noted by Ulrich Windl of the Universitat Regensburg.
	Portability:
		Add the ability to read IPv6 interface addresses into class
			'w' under FreeBSD (and possibly others).  From Jun
			Kuriyama of IMG SRC, Inc. and the FreeBSD Project.
		Replace code for finding the number of CPUs on HPUX.
		NCRUNIX MP-RAS 3.02 SO_REUSEADDR socket option does not
			work properly causing problems if the accept()
			fails and the socket needs to be reopened.  Patch
			from Tom Moore of NCR.
		NetBSD uses a .0 extension of formatted man pages.  From
			Andrew Brown of Crossbar Security.
		Return to using the IPv6 AI_DEFAULT flag instead of AI_V4MAPPED
			for calls to getipnodebyname().  The Linux
			implementation is broken so AI_ADDRCONFIG is stripped
			under Linux.  From John Beck of Sun Microsystems and
			John Kennedy of Cal State University, Chico.
	CONFIG: Catch invalid addresses containing a ',' at the wrong place.
		Patch from Neil Rickert of Northern Illinois University.
	CONFIG: New variables for the new sendmail options:
		confCACERT_PATH			CACERTPath
		confCACERT			CACERTFile
		confCLIENT_CERT			ClientCertFile
		confCLIENT_KEY			ClientKeyFile

	CONFIG: Add TLS information to the Received: header.
	CONFIG: Call tls_client ruleset from check_mail in case it wasn't
		called due to a STARTTLS command.
	CONFIG: If TLS_PERM_ERR is defined, TLS related errors are permanent
		instead of temporary.
	CONFIG: FEATURE(`relay_hosts_only') didn't work in combination with
		the access map and relaying to a domain without using a To:
		tag.  Problem noted by Mark G. Thomas of Mark G. Thomas
		Consulting.
	CONFIG: Set confEBINDIR to /usr/sbin to match the devtools entry in
		OSTYPE(`linux') and OSTYPE(`mklinux').  From Tim Pierce of
		RootsWeb.com.
	CONFIG: Make sure FEATURE(`nullclient') doesn't use aliasing and
		forwarding to make it as close to the old behavior as
		possible.  Problem noted by George W. Baltz of the
		University of Maryland.
	CONFIG: Added OSTYPE(`darwin') for Mac OS X and Darwin users.  From
		Wilfredo Sanchez of Apple Computer, Inc.
	CONFIG: Changed the map names used by FEATURE(`ldap_routing') from
		ldap_mailhost and ldap_mailroutingaddress to ldapmh and
		ldapmra as underscores in map names cause problems if
		underscore is in OperatorChars.  Problem noted by Bob Zeitz
		of the University of Alberta.
	CONFIG: Apply blacklist_recipients also to hosts in class {w}.
		Patch from Michael Tratz of Esosoft Corporation.
	CONFIG: Use A=TCP ... instead of A=IPC ... in SMTP mailers.
	CONTRIB: Add link_hash.sh to create symbolic links to the hash
		of X.509 certificates.
	CONTRIB: passwd-to-alias.pl:  More protection from special characters;
		treat special shells as root aliases; skip entries where the
		GECOS full name and username match.  From Ulrich Windl of the
		Universitat Regensburg.
	CONTRIB: qtool.pl: Add missing last_modified_time method and fix a
		typo.  Patch from Graeme Hewson of Oracle.
	CONTRIB: re-mqueue.pl: Improve handling of a race between re-mqueue
		and sendmail.  Patch from Graeme Hewson of Oracle.
	CONTRIB: re-mqueue.pl: Don't exit(0) at end so can be called as
		subroutine Patch from Graeme Hewson of Oracle.
	CONTRIB: Add movemail.pl (move old mail messages between queues by
		calling re-mqueue.pl) and movemail.conf (configuration
		script for movemail.pl).  From Graeme Hewson of Oracle.
	CONTRIB: Add cidrexpand (expands CIDR blocks as a preprocessor to
		makemap).  From Derek J. Balling of Yahoo,Inc.
	DEVTOOLS: INSTALL_RAWMAN installation option mistakenly applied any
		extension modifications (e.g., MAN8EXT) to the installation
		target.  Patch from James Ralston of Carnegie Mellon
		University.
	DEVTOOLS: Add support for SunOS 5.9.
	DEVTOOLS: New option confLN contains the command used to create
		links.
	LIBSMDB: Berkeley DB 2.X and 3.X errors might be lost and not
		reported.
	MAIL.LOCAL: DG/UX portability.  Problem noted by Tim Boyer of
		Denman Tire Corporation.
	MAIL.LOCAL: Prevent a possible DoS attack when compiled with
		-DCONTENTLENGTH.  Based on patch from 3APA3A@SECURITY.NNOV.RU.
	MAILSTATS: Fix usage statement (-p and -o are optional).
	MAKEMAP: Change man page layout as workaround for problem with nroff
		and -man on Solaris 7.  Patch from Larry Williamson.
	RMAIL: AIX 4.3 has snprintf().  Problem noted by David Hayes of
		Black Diamond Equipment, Limited.
	RMAIL: Prevent a segmentation fault if the incoming message does not
		have a From line.
	VACATION: Read all of the headers before deciding whether or not
		to respond instead of stopping after finding recipient.
	Added Files:

8.10.2/8.10.2	2000/06/07
	SECURITY: Work around broken Linux setuid() implementation.
		On Linux, a normal user process has the ability to subvert
		the setuid() call such that it is impossible for a root
		process to drop its privileges.  Problem noted by Wojciech
		Purczynski of elzabsoft.pl.
	SECURITY: Add more vigilance around set*uid(), setgid(), setgroups(),
		initgroups(), and chroot() calls.
	Added Files:
		test/t_setuid.c

8.10.1/8.10.1	2000/04/06
	SECURITY: Limit the choice of outgoing (client-side) SMTP
		Authentication mechanisms to those specified in
		AuthMechanisms to prevent information leakage.  We do not
		recommend use of PLAIN for outgoing mail as it sends the
		password in clear text to possibly untrusted servers.  See
		cf/README's DefaultAuthInfo section for additional information.
	Copy the ident argument for openlog() to avoid problems on some
		OSs.  Based on patch from Rob Bajorek from Webhelp.com.
	Avoid bogus error message when reporting an alias line as too long.
	Avoid bogus socket error message if sendmail.cf version level is
		greater than sendmail binary supported version.  Patch
		from John Beck of Sun Microsystems.
	Prevent a malformed ruleset (missing right hand side) from causing
		a segmentation fault when using address test mode.  Based on
		patch from John Beck of Sun Microsystems.
	Prevent memory leak from use of NIS maps and yp_match(3).  Problem
		noted by Gil Kloepfer of the University of Texas at Austin.
	Fix queue file permission checks to allow for TrustedUser ownership.
	Change logging of errors from the trust_auth ruleset to LogLevel 10
		or higher.
	Avoid simple password cracking attacks against SMTP AUTH by using
		exponential delay after too many tries within one connection.
	Encode an initial empty AUTH challenge as '=', not as empty string.
	Avoid segmentation fault on EX_SOFTWARE internal error logs.
		Problem noted by Allan E Johannesen of Worcester
		Polytechnic Institute.
	Ensure that a header check which resolves to $#discard actually
		discards the message.
	Emit missing value warnings for aliases with no right hand side
		when newaliases is run instead of only when delivery is
		attempted to the alias.
	Remove AuthOptions missing value warning for consistency with other
		flag options.
	Portability:
		SECURITY: Specify a run-time shared library search path for
			AIX 4.X instead of using the dangerous AIX 4.X
			linker semantics.  AIX 4.X users should consult
			sendmail/README for further information.  Problem
			noted by Valdis Kletnieks of Virginia Tech.
		Avoid use of strerror(3) call.  Problem noted by Charles
			Levert of Ecole Polytechnique de Montreal.
		DGUX requires -lsocket -lnsl and has a non-standard install
			program.  From Tim Boyer of Denman Tire Corporation.
		HPUX 11.0 has a broken res_search() function.
		Updates to devtools/OS/NeXT.3.X, NeXT.4.X, and NEXTSTEP.4.X
			from J. P. McCann of E I A.
		Digital UNIX/Compaq Tru64 5.0 now includes snprintf(3).
			Problem noted by Michael Long of Info Avenue Internet
			Services, LLC.
		Modern (post-199912) OpenBSD versions include working
			strlc{at,py}(3) functions.  From Todd C. Miller of
			Courtesan Consulting.
		SINIX doesn't have random(3).  From Gerald Rinske of
			Siemens Business Services.
	CONFIG: Change error message about unresolvable sender domain to
		include the sender address.  Proposed by Wolfgang Rupprecht
		of WSRCC.
	CONFIG: Fix usenet mailer calls.
	CONFIG: If RELAY_MAILER_FLAGS is not defined, use SMTP_MAILER_FLAGS
		to be backward compatible with 8.9.
	CONFIG: Change handling of default case @domain for virtusertable
		to allow for +*@domain to deal with +detail.
	CONTRIB: Remove converting.sun.configs -- it is obsolete.
	DEVTOOLS: confUBINMODE was being ignored.  Fix from KITAZIMA, Tuneki
		of NEC.
	DEVTOOLS: Add to NCR platform list and include the architecture
		(i486).  From Tom J. Moore of NCR.
	DEVTOOLS: SECURITY: Change method of linking with sendmail utility
		libraries to work around the AIX 4.X and SunOS 4.X linker's
		overloaded -L option.  Problem noted by Valdis Kletnieks of
		Virginia Tech.
	DEVTOOLS: configure.sh was overriding the user's choice for
		confNROFF.  Problem noted by Glenn A. Malling of Syracuse
		University.
	DEVTOOLS: New variables conf_prog_LIB_POST and confBLDVARIANT added
		for other internal projects but included in the open source
		release.
	LIBSMDB: Check for ".db" instead of simply "db" at the end of the
		map name to determine whether or not to add the extension.
		This fixes makemap when building the userdb file.  Problem
		noted by Andrew J Cole of the University of Leeds.
	LIBSMDB: Allow a database to be opened for updating and created if
		it doesn't already exist.  Problem noted by Rand Wacker of
		Sendmail.
	LIBSMDB: If type is SMDB_TYPE_DEFAULT and both NEWDB and NDBM are
		available, fall back to NDBM if NEWDB open fails.  This
		fixes praliases.  Patch	from John Beck of Sun Microsystems.
	LIBSMUTIL: safefile()'s SFF_NOTEXCL check was being misinterpreted
		as SFF_NOWRFILES.
	OP.ME: Clarify some issues regarding mailer flags.  Suggested by
		Martin Mokrejs of The Charles University and Neil Rickert of
		Northern Illinois University.
	PRALIASES: Restore 8.9.X functionality of being able to search for
		particular keys in a database by specifying the keys on the
		command line.  Man page updated accordingly.  Patch from
		John Beck of Sun Microsystems.
	VACATION: SunOS 4.X portability from Charles Levert of Ecole
		Polytechnique de Montreal.
	VACATION: Fix -t option which is ignored but available for
		compatibility with Sun's version, based on patch from

	    *************************************************************
	SECURITY: The safe file checks now back track through symbolic
		links to make sure the files can't be compromised due
		to poor permissions on the parent directories of the
		symbolic link target.
	SECURITY: Only root, TrustedUser, and users in class t can rebuild
		the alias map.  Problem noted by Michal Zalewski of the
		"Internet for Schools" project (IdS).
	SECURITY: There is a potential for a denial of service attack if
		the AutoRebuildAliases option is set as a user can kill the
		sendmail process while it is rebuilding the aliases file
		(leaving it in an inconsistent state).  This option and
		its use is deprecated and will be removed from a future
		version of sendmail.
	SECURITY: Make sure all file descriptors (besides stdin, stdout, and
		stderr) are closed before restarting sendmail.  Problem noted
		by Michal Zalewski of the "Internet for Schools" project
		(IdS).
	Begin using /etc/mail/ for sendmail related files.  This affects
		a large number of files.  See cf/README for more details.
	The directory structure of the distribution has changed slightly
		for easier code sharing among the programs.
	Support SMTP AUTH (see RFC 2554).  New macros for this purpose
		are ${auth_authen}, ${auth_type}, and ${auth_author}
		which hold the client's authentication credentials,
		the mechanism used for authentication, and the
		authorization identity (i.e., the AUTH= parameter if
		supplied).  Based on code contributed by Tim Martin of CMU.
	On systems which use the Torek stdio library (all of the BSD
		distributions), use memory-buffered files to reduce
		file system overhead by not creating temporary files on
		disk.  Contributed by Exactis.com, Inc.
	New option DataFileBufferSize to control the maximum size of a
		memory-buffered data (df) file before a disk-based file is
		used.  Contributed by Exactis.com, Inc.
	New option XscriptFileBufferSize to control the maximum size of a
		memory-buffered transcript (xf) file before a disk-based
		file is used.  Contributed by Exactis.com, Inc.
	sendmail implements RFC 2476 (Message Submission), e.g., it can
		now listen on several different ports.  Use:
		O DaemonPortOptions=Name=MSA, Port=587, M=E
		to run a Message Submission Agent (MSA); this is turned
		on by default in m4-generated .cf files; it can be turned
		off with FEATURE(`no_default_msa').
	The 'XUSR' SMTP command is deprecated.  Mail user agents should
		begin using RFC 2476 Message Submission for initial user
		message submission.  XUSR may disappear from a future release.
	The new '-G' (relay (gateway) submission) command line option
		indicates that the message being submitted from the command
		line is for relaying, not initial submission.  This means
		the message will be rejected if the addresses are not fully
		qualified and no canonicalization will be done.  Future
		releases may even reject improperly formed messages.
	The '-U' (initial user submission) command line option is
		deprecated and may be removed from a future release.
		Mail user agents should begin using '-G' to indicate that
		this is a relay submission (the inverse of -U).
	The next release of sendmail will assume that any message submitted
		from the command line is an initial user submission and act
		accordingly.
	If sendmail doesn't have enough privileges to run a .forward
		program or deliver to file as the owner of that file, the
		address is marked as unsafe.  This means if RunAsUser is
		set, users won't be able to use programs or delivery to
		files in their .forward files.  Administrators can override
		this by setting the DontBlameSendmail option to the new
		setting NonRootSafeAddr.
	Allow group or world writable directories if the sticky bit is set
		on the directory and DontBlameSendmail is set to
		TrustStickyBit.  Based on patch from Chris Metcalf of
		InCert Software.
	Prevent logging of unsafe directory paths for non-existent forward
		files if the new DontWarnForwardFileInUnsafeDirPath bit is
		set in the DontBlameSendmail option.  Requested by many.
	New Timeout.control option to limit the total time spent satisfying
		a control socket request.
	New Timeout.resolver options for controlling BIND resolver
		settings:
		Timeout.resolver.retrans
			Sets the resolver's retransmission time interval (in
			seconds).  Sets both Timeout.resolver.retrans.first
			and Timeout.resolver.retrans.normal.
		Timeout.resolver.retrans.first
			Sets the resolver's retransmission time interval (in
			seconds) for the first attempt to deliver a message.
		Timeout.resolver.retrans.normal
			Sets the resolver's retransmission time interval (in
			seconds) for all resolver lookups except the first
			delivery attempt.
		Timeout.resolver.retry
			Sets the number of times to retransmit a resolver
			query.  Sets both Timeout.resolver.retry.first
			and Timeout.resolver.retry.normal.
		Timeout.resolver.retry.first
			Sets the number of times to retransmit a resolver
			query for the first attempt to deliver a message.
		Timeout.resolver.retry.normal
			Sets the number of times to retransmit a resolver
			query for all resolver lookups except the first
			delivery attempt.
		Contributed by Exactis.com, Inc.
	Support multiple queue directories.  To use multiple queues, supply
		a QueueDirectory option value ending with an asterisk.  For
		example, /var/spool/mqueue/q* will use all of the
		directories or symbolic links to directories beginning with
		'q' in /var/spool/mqueue as queue directories.  Keep in
		mind, the queue directory structure should not be changed
		while sendmail is running.  Queue runs create a separate
		process for running each queue unless the verbose flag is
		given on a non-daemon queue run.  New items are randomly
		assigned to a queue.  Contributed by Exactis.com, Inc.
	Support different directories for qf, df, and xf queue files; if
		subdirectories or symbolic links to directories of those names
		exist in the queue directories, they are used for the
		corresponding queue files.  Keep in mind, the queue
		directory structure should not be changed while sendmail is
		running.  Proposed by Mathias Koerber of Singapore
		Telecommunications Ltd.
	New queue file naming system which uses a filename guaranteed to be
		unique for 60 years.  This allows queue IDs to be assigned
		without fancy file system locking.  Queued items can be
		moved between queues easily.  Contributed by Exactis.com,
		Inc.
	Messages which are undeliverable due to temporary address failures
		(e.g., DNS failure) will now go to the FallBackMX host, if
		set.  Contributed by Exactis.com, Inc.
	New command line option '-L tag' which sets the identifier used for
		syslog.  Contributed by Exactis.com, Inc.
	QueueSortOrder=Filename will sort the queue by filename.  This
		avoids opening and reading each queue file when preparing
		to run the queue.  Contributed by Exactis.com, Inc.
	Shared memory counters and microtimers functionality has been
		donated by Exactis.com, Inc.
	The SCCS ID tags have been replaced with RCS ID tags.
	Allow trusted users (those on a T line or in $=t) to set the
		QueueDirectory (Q) option without an X-Authentication-Warning:
		being added.  Suggested by Michael K. Sanders.
	IPv6 support based on patches from John Kennedy of Cal State
		University, Chico, Motonori Nakamura of Kyoto University,
		and John Beck of Sun Microsystems.
	In low-disk space situations, where sendmail would previously refuse
		connections, still accept them, but only allow ETRN commands.
		Suggested by Mathias Koerber of Singapore Telecommunications
		Ltd.
	The [IPC] builtin mailer now allows delivery to a UNIX domain socket
		on systems which support them.  This can be used with LMTP
		local delivery agents which listen on a named socket.  An
		example mailer might be:
			Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n,
				S=10, R=20/40, T=DNS/RFC822/X-Unix,
				A=FILE /var/run/lmtpd
		Code contributed by Lyndon Nerenberg of Messaging Direct.
	The [TCP] builtin mailer name is now deprecated.  Use [IPC]
		instead.
	The first mailer argument in the [IPC] mailer is now checked for a
		legitimate value.  Possible values are TCP (for TCP/IP
		connections), IPC (which will be deprecated in a future
		version), and FILE (for UNIX domain socket delivery).
	PrivacyOptions=goaway no longer includes the noetrn and the noreceipts
		flags.
	PrivacyOptions=nobodyreturn instructs sendmail not to include the
		body of the original message on delivery status
		notifications.
	Don't announce DSN if PrivacyOptions=noreceipts is set.  Problem noted
		by Dan Bernstein, fix from Robert Harker of Harker Systems.
	Accept the SMTP RSET command even when rejecting commands due to TCP
		Wrappers or the check_relay ruleset.  Problem noted by
		Steve Schweinhart of America Online.
	Warn if OperatorChars is set multiple times.  OperatorChars should
		not be set after rulesets are defined.  Suggested by
		Mitchell Blank Jr of Exec-PC.
	Do not report temporary failure on delivery to files.  In
		interactive delivery mode, this would result in two SMTP
		responses after the DATA command.  Problem noted by
		Nik Conwell of Boston University.
	Check file close when mailing to files.  Problem noted by Nik
		Conwell of Boston University.
	Avoid a segmentation fault when using the LDAP map.  Patch from
		Curtis W. Hillegas of Princeton University.
	Always bind to the LDAP server regardless of whether you are using
		ldap_open() or ldap_init().  Fix from Raj Kunjithapadam of
		@Home Network.
	New ruleset trust_auth to determine whether a given AUTH=
		parameter of the MAIL command should be trusted.  See SMTP
		AUTH, cf/README, and doc/op/op.ps.
	Allow new named config file rules check_vrfy, check_expn, and
		check_etrn for VRFY, EXPN, and ETRN commands, respectively,
		similar to check_rcpt etc.
	Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr},
		${mail_mailer}, ${mail_host}, ${mail_addr} that hold
		the results of parsing the RCPT and MAIL arguments, i.e.
		the resolved triplet from $#mailer $@host $:addr.
		From Kari Hurtta of the Finnish Meteorological Institute.
	New macro ${client_resolve} which holds the result of the resolve
		call for ${client_name}: OK, FAIL, FORGED, TEMP.  Proposed
		by Kari Hurtta of the Finnish Meteorological Institute.
	New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold
		the corresponding DSN parameter values.  Proposed by
		Mathias Herberts.
	New macro ${msg_size} which holds the value of the SIZE= parameter,
		i.e., usually the size of the message (in an ESMTP dialogue),
		before the message has been collected, thereafter it holds
		the message size as computed by sendmail (and can be used
		in check_compat).
	The macro ${deliveryMode} now specifies the current delivery mode
		sendmail is using instead of the value of the DeliveryMode
		option.
	New macro ${ntries} holds the number of delivery attempts.
	Drop explicit From: if same as what would be generated only if it is
		a local address.  From Motonori Nakamura of Kyoto University.
	Write pid to file also if sendmail only processes the queue.
		Proposed by Roy J. Mongiovi of Georgia Tech.
	Log "low on disk space" only when necessary.
	New macro ${load_avg} can be used to check the current load average.
		Suggested by Scott Gifford of The Internet Ramp.
	Return-Receipt-To: header implies DSN request if option RrtImpliesDsn
		is set.
	Flag -S for maps to specify the character which is substituted
		for spaces (instead of the default given by O BlankSub).
	Flag -D for maps: perform no lookup in deferred delivery mode.
		This flag is set by default for the host map.  Based on a
		proposal from Ian MacPhedran of the University of Saskatchewan.
	Open maps only on demand, not at startup.
	Log warning about unsupported IP address families.
	New option MaxHeadersLength allows to specify a maximum length
		of the sum of all headers.  This can be used to prevent
		a denial-of-service attack.
	New option MaxMimeHeaderLength which limits the size of MIME
		headers and parameters within those headers.  This option
		is intended to protect mail user agents from buffer
		overflow attacks.
	Added option MaxAliasRecursion to specify the maximum depth of
		alias recursion.
	New flag F=6 for mailers to strip headers to seven bit.
	Map type syslog to log the key via syslogd.
	Entries in the alias file can be continued by putting a backslash
		directly before the newline.
	New option DeadLetterDrop to define the location of the system-wide
		dead.letter file, formerly hardcoded to
		/usr/tmp/dead.letter.  If this option is not set (the
		default), sendmail will not attempt to save to a
		system-wide dead.letter file if it can not bounce the mail
		to the user nor postmaster.  Instead, it will rename the qf
		file as it has in the past when the dead.letter file
		could not be opened.
	New option PidFile to define the location of the pid file.  The
		value of this option is macro expanded.
	New option ProcessTitlePrefix specifies a prefix string for the
		process title shown in 'ps' listings.
	New macros for use with the PidFile and ProcessTitlePrefix options
		(along with the already existing macros):
		${daemon_info}      Daemon information, e.g.
		                    SMTP+queueing@00:30:00
		${daemon_addr}	    Daemon address, e.g., 0.0.0.0
		${daemon_family}    Daemon family, e.g., inet, inet6, etc.
		${daemon_name}      Daemon name, e.g., MSA.
		${daemon_port}	    Daemon port, e.g., 25
		${queue_interval}   Queue run interval, e.g., 00:30:00
	New macros especially for virtual hosting:
		${if_name}	hostname of interface of incoming connection.
		${if_addr}	address of interface of incoming connection.
		The latter is only set if the interface does not belong to the
		loopback net.
	If a message being accepted via a method other than SMTP and
		would be rejected by a header check, do not send the message.
		Suggested by Phil Homewood of Mincom Pty Ltd.
	Don't strip comments for header checks if $>+ is used instead of $>.
		Provide header value as quoted string in the macro
		${currHeader} (possibly truncated to MAXNAME).  Suggested by
		Jan Krueger of Unix-AG of University of Hannover.
		The length of the header value is stored in ${hdrlen}.
	H*: allows to specify a default ruleset for header checks.  This
		ruleset will only be called if the individual header does
		not have its own ruleset assigned.  Suggested by Jan
		Krueger of Unix-AG of University of Hannover.
		The name of the header field stored in ${hdr_name}.
	Comments (i.e., text within parentheses) in rulesets are not
		removed if the config file version is greater than or equal
		to 9.  For example, "R$+ ( 1 )		$@ 1" matches the
		input "token (1)" but does not match "token".
	Avoid removing the Content-Transfer-Encoding MIME header on
		MIME messages.  Problem noted by Sigurbjorn B. Larusson of
		Multimedia Consumer Services.  Fix from Per Hedeland of
		Ericsson.
	Avoid duplicate Content-Transfer-Encoding MIME header on
		messages with 8-bit text in headers.  Problem noted by
		Per Steinar Iversen of Oslo College.  Fix from Per Hedeland
		of Ericsson.
	Avoid keeping maps locked longer than necessary when re-opening a
		modified database map file.  Problem noted by Chris Adams
		of Renaissance Internet Services.
	Resolving to the $#error mailer with a temporary failure code (e.g.,
		$#error $@ tempfail $: "400 Temporary failure") will now
		queue up the message instead of bouncing it.
	Be more liberal in acceptable responses to an SMTP RSET command as
		standard does not provide any indication of what to do when
		something other than 250 is received.  Based on a patch
		from Steve Schweinhart of America Online.
	New option TrustedUser allows to specify a user who can own
		important files instead of root.  This requires HASFCHOWN.
	Fix USERDB conditional so compiling with NEWDB or HESIOD and
		setting USERDB=0 works.  Fix from Jorg Zanger of Schock.
	Fix another instance (similar to one in 8.9.3) of a network failure
		being mis-logged as "Illegal Seek" instead of whatever
		really went wrong.  From John Beck of Sun Microsystems.
	$? tests also whether the macro is non-null.
	Print an error message if a mailer definition contains an invalid
		equate name.
	New mailer equate /= to specify a directory to chroot() into before
		executing the mailer program.  Suggested by Igor Vinokurov.
	New mailer equate W= to specify the maximum time to wait for the
		mailer to return after sending all data to it.
	Only free memory from the process list when adding a new process
		into a previously filled slot.  Previously, the memory was
		freed at removal time.  Since removal can happen in a
		signal handler, this may leave the memory map in an
		inconsistent state.  Problem noted by Jeff A. Earickson and
		David Cooley of Colby College.
	When using the UserDB @hostname catch-all, do not try to lookup
		local users in the passwd file.  The UserDB code has
		already decided the message will be passed to another host
		for processing.  Fix from Tony Landells of Burdett
		Buckeridge Young Limited.
	Support LDAP authorization via either a file containing the
		password or Kerberos V4 using the new map options
		'-ddistinguished_name', '-Mmethod', and '-Pfilename'.  The
		distinguished_name is who to login as.  The method can be
		one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or
		LDAP_AUTH_KRBV4.  The filename is the file containing the
		secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos
		ticket file for LDAP_AUTH_KRBV4.  Patch from Booker Bense
		of Stanford University.
	The ldapx map has been renamed to ldap.  The use of ldapx is
		deprecated and will be removed in a future version.
	If the result of an LDAP search returns a multi-valued attribute
		and the map has the column delimiter set, it turns that
		response into a delimiter separated string.  The LDAP map
		will traverse multiple entries as well.  LDAP alias maps
		automatically set the column delimiter to the comma.
		Based on patch from Booker Bense of Stanford University and
		idea from Philip A. Prindeville of Mirapoint, Inc.
	Support return of multiple values for a single LDAP lookup.  The
		values to be returned should be in a comma separated string.
		For example, `-v "email,emailother"'.  Patch from
		Curtis W. Hillegas of Princeton University.
	Allow the use of LDAP for alias maps.
	If no LDAP attributes are specified in an LDAP map declaration, all
		attributes found in the match will be returned.
	Prevent commas in quoted strings in the AliasFile value from
		breaking up a single entry into multiple entries.  This is
		needed for LDAP alias file specifications to allow for
		comma separated key and value strings.
	Keep connections to LDAP server open instead of opening and closing
		for each lookup.  To reduce overhead, sendmail will cache
		connections such that multiple maps which use the same
		host, port, bind DN, and authentication will only result in
		a single connection to that host.
	Put timeout in the proper place for USE_LDAP_INIT.
	Be more careful about checking for errors and freeing memory on
		LDAP lookups.
	Use asynchronous LDAP searches to save memory and network
		resources.
	Do not copy LDAP query results if the map's match only flag is set.
	Increase portability to the Netscape LDAP libraries.
	Change the parsing of the LDAP filter specification.  '%s' is still
		replaced with the literal contents of the map lookup key --
		note that this means a lookup can be done using the LDAP
		special characters.  The new '%0' token can be used instead
		of '%s' to encode the key buffer according to RFC 2254.
		For example, if the LDAP map specification contains '-k
		"(user=%s)"' and a lookup is done on "*", this would be
		equivalent to '-k "(user=*)"' -- matching ANY record with a
		user attribute.  Instead, if the LDAP map specification
		contains '-k "(user=%0)"' and a lookup is done on "*", this
		would be equivalent to '-k "(user=\2A)"' -- matching a user
		with the name "*".
	New LDAP map flags: "-1" requires a single match to be returned, if
		more than one is returned, it is equivalent to no records
		being found; "-r never|always|search|find" sets the LDAP
		alias dereference option; "-Z size" limits the number of
		matches to return.
	New option LDAPDefaultSpec allows a default map specification for
		LDAP maps.  The value should only contain LDAP specific
		settings such as "-h host -p port -d bindDN", etc.  The
		settings will be used for all LDAP maps unless they are
		specified in the individual map specification ('K'
		command).  This option should be set before any LDAP maps
		are defined.
	Prevent an NDBM alias file opening loop when the NDBM open
		continually fails.  Fix from Roy J. Mongiovi of Georgia
		Tech.
	Reduce memory utilization for smaller symbol table entries.  In
		particular, class entries get much smaller, which can be
		important if you have large classes.
	On network-related temporary failures, record the hostname which
		gave error in the queued status message.  Requested by
		Ulrich Windl of the Universitat Regensburg.
	Add new F=% mailer flag to allow for a store and forward
		configuration.  Mailers which have this flag will not attempt
		delivery on initial receipt of a message or on queue runs
		unless the queued message is selected using one of the
		-qI/-qR/-qS queue run modifiers or an ETRN request.  Code
		provided by Philip Guenther of Gustavus Adolphus College.
	New option ControlSocketName which, when set, creates a daemon
		control socket.  This socket allows an external program to
		control and query status from the running sendmail daemon
		via a named socket, similar to the ctlinnd interface to the
		INN news server.  Access to this interface is controlled by
		the UNIX file permissions on the named socket on most UNIX
		systems (see sendmail/README for more information).  An
		example control program is provided as contrib/smcontrol.pl.
	Change the default values of QueueLA from 8 to (8 * numproc) and
		RefuseLA from 12 to (12 * numproc) where numproc is the
		number of processors online on the system (if that can be
		determined).  For single processor machines, this change
		has no effect.
	Don't return body of message to postmaster on "Too many hops" bounces.
		Based on fix from Motonori Nakamura of Kyoto University.
	Give more detailed DSN descriptions for some cases.  Patch from
		Motonori Nakamura of Kyoto University.
	Logging of alias, forward file, and UserDB expansion now happens
		at LogLevel 11 or higher instead of 10 or higher.
	Logging of an envelope's complete delivery (the "done" message) now
		happens at LogLevel 10 or higher instead of 11 or higher.
	Logging of TCP/IP or UNIX standard input connections now happens at
		LogLevel 10 or higher.  Previously, only TCP/IP connections
		were logged, and on at LogLevel 12 or higher.  Setting
		LogLevel to 10 will now assist users in tracking frequent
		connection-based denial of service attacks.
	Log basic information about authenticated connections at LogLevel
		10 or higher.
	Log SMTP Authentication mechanism and author when logging the sender
		information (from= syslog line).
	Log the DSN code for each recipient if one is available as a new
		equate (dsn=).
	Macro expand PostmasterCopy and DoubleBounceAddress options.
	New "ph" map for performing ph queries in rulesets, see
		sendmail/README for details.  Contributed by Mark Roth
		of the University of Illinois at Urbana-Champaign.
	Detect temporary lookup failures in the host map if looking up a
		bracketed IP address.  Problem noted by Kari Hurtta of the
		Finnish Meteorological Institute.
	Do not report a Remote-MTA on local deliveries.  Problem noted by
		Kari Hurtta of the Finnish Meteorological Institute.
	When a forward file points to an alias which runs a program, run
		the program as the default user and the default group, not
		the forward file user.  This change also assures the
		:include: directives in aliases are also processed using
		the default user and group.  Problem noted by Sergiu
		Popovici of DNT Romania.
	Prevent attempts to save a dead.letter file for a user with
		no home directory (/no/such/directory).  Problem noted by
		Michael Brown of Finnigan FT/MS.
	Include message delay and number of tries when logging that a
		message has been completely delivered (LogLevel of 10 or
		above).  Suggested by Nick Hilliard of Ireland Online.
	Log the sender of a message even if none of the recipients were
		accepted.  If some of the recipients were rejected, it is
		helpful to know the sender of the message.
	Check the root directory (/) when checking a path for safety.
		Problem noted by John Beck of Sun Microsystems.
	Prevent multiple responses to the DATA command if DeliveryMode is
		interactive and delivering to an alias which resolves to
		multiple files.
	Macros in the helpfile are expanded if the helpfile version is 2 or
		greater (see below); the help function doesn't print the
		version of sendmail any longer, instead it is placed in
		the helpfile ($v).  Suggested by Chuck Foster of UUNET
		PIPEX.  Additionally, comment lines (starting with #) are
		skipped and a version line (#vers) is introduced.  The
		helpfile version for 8.10.0 is 2, if no version or an older
		version is found, a warning is logged.  The '#vers'
		directive should be placed at the top of the help file.
	Use fsync() when delivering to a file to guarantee the delivery to
		disk succeeded.  Suggested by Nick Christenson.
	If delivery to a file is unsuccessful, truncate the file back to its
		length before the attempt.
	If a forward points to a filename for delivery, change to the
		user's uid before checking permissions on the file.  This
		allows delivery to files on NFS mounted directories where
		root is remapped to nobody.  Problem noted by Harald
		Daeubler of Universitaet Ulm.
	purgestat and sendmail -bH purge only expired (Timeout.hoststatus)
		host status files, not all files.
	Any macros stored in the class $={persistentMacros} will be saved
		in the queue file for the message and set when delivery
		is attempted on the queued item.  Suggested by Kyle Jones of
		Wonderworks Inc.
	Add support for storing information between rulesets using the new
		macro map class.  This can be used to store information
		between queue runs as well using $={persistentMacros}.
		Based on an idea from Jan Krueger of Unix-AG of University
		of Hannover.
	New map class arith to allow for computations in rules.  The
		operation (+, -, *, /, l (for less than), and =) is given
		as key.  The two operands are specified as arguments; the
		lookup returns the result of the computation.  For example,
		"$(arith l $@ 4 $@ 2 $)" will return "FALSE" and
		"$(arith + $@ 4 $@ 2 $)" will return "6".
	Add new syntax for header declarations which decide whether to
		include the header based on a macro rather than a mailer
		flag:
			H?${MyMacro}?X-My-Header: ${MyMacro}
		This should be used along with $={persistentMacros}.
		It can be used for adding headers to a message based on
		the results of check_* and header check rulesets.
	Allow new named config file rule check_eoh which is called after
		all of the headers have been collected.  The input to the
		ruleset the number of headers and the size of all of the
		headers in bytes separated by $|.  This ruleset along with
		the macro storage map can be used to correlate information
		gathered between headers and to check for missing headers.
		See cf/README or doc/op/op.ps for an example.
	Change the default for the MeToo option to True to correspond
		to the clarification in the DRUMS SMTP Update spec.  This
		option is deprecated and will be removed from a future
		version.
	Change the sendmail binary default for SendMimeErrors to True.
	Change the sendmail binary default for SuperSafe to True.
	Display ruleset names in debug and address test mode output
		if referencing a named ruleset.
	New mailer equate m= which will limit the number of messages
		delivered per connection on an SMTP or LMTP mailer.
	Improve QueueSortOrder=Host by reversing the hostname before
		using it to sort.  Now all the same domains are really run
		through the queue together.  If they have the same MX host,
		then they will have a much better opportunity to use the
		connection cache if available.  This should be a reasonable
		performance improvement.  Patch from Randall Winchester of
		the University of Maryland.
	If a message is rejected by a header check ruleset, log who would
		have received the message if it had not been rejected.
	New "now" value for Timeout.queuereturn to bounce entries from the
		queue immediately.  No delivery attempt is made.
	Increase sleeping time exponentially after too many "bad" commands
		up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}-
		COMMANDS).
	New option ClientPortOptions similar to DaemonPortOptions
		but for outgoing connections.
	New suboptions for DaemonPortOptions: Name (a name used for
		error messages and logging) and Modifiers, i.e.
			a	require authentication
			b	bind to interface through which mail has
				been received
			c	perform hostname canonification
			f	require fully qualified hostname
			h	use name of interface for outgoing HELO
				command
			C	don't perform hostname canonification
			E	disallow ETRN (see RFC 2476)
	New suboption for ClientPortOptions: Modifiers, i.e.
			h	use name of interface for HELO command
	The version number for queue files (qf) has been incremented to 4.
	Log unacceptable HELO/EHLO domain name attempts if LogLevel is set
		to 10 or higher.  Suggested by Rick Troxel of the National
		Institutes of Health.
	If a mailer dies, print the status in decimal instead of octal
		format.  Suggested by Michael Shapiro of Sun Microsystems.
	Limit the length of all MX records considered for delivery to 8k.
	Move message priority from sender to recipient logging.  Suggested by
		Ulrich Windl of the Universitat Regensburg.
	Add support for Berkeley DB 3.X.
	Add fix for Berkeley DB 2.X fcntl() locking race condition.
		Requires a post-2.7.5 version of Berkeley DB.
	Support writing traffic log (sendmail -X option) to a FIFO.
		Patch submitted by Rick Heaton of Network Associates, Inc.
	Do not ignore Timeout settings in the .cf file when a Timeout
		sub-options is set on the command line.  Problem noted by
		Graeme Hewson of Oracle.
	Randomize equal preference MX records each time delivery is
		attempted via a new connection to a host instead of once per
		session.  Suggested by Scott Salvidio of Compaq.
	Implement enhanced status codes as defined by RFC 2034.
	Add [hostname] to class w for the names of all interfaces unless
		DontProbeInterfaces is set. This is useful for sending mails
		to hosts which have dynamically assigned names.
	If a message is bounced due to bad MIME conformance, avoid bouncing
		the bounce for the same reason.  If the body is not 8-bit
		clean, and EightBitMode isn't set to pass8, the body will
		not be included in the bounce.  Problem noted by Valdis
		Kletnieks of Virginia Tech.
	The timeout for sending a message via SMTP has been changed from
		'${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which
		simply checks for progress on sending data every 5 minutes.
		This will detect the inability to send information quicker
		and reduce the number of processes simply waiting to
		timeout.
	Prevent a segmentation fault on systems which give a partial filled
		interface address structure when loading the system network
		interface addresses.  Fix from Reinier Bezuidenhout of
		Nanoteq.
	Add a compile-time configuration macro, MAXINTERFACES, which
		indicates the number of interfaces to read when probing
		for hostnames and IP addresses for class w ($=w).  The
		default value is 512.  Based on idea from Reinier
		Bezuidenhout of Nanoteq.
	If the RefuseLA option is set to 0, do not reject connections based
		on load average.
	Allow ruleset 0 to have a name.  Problem noted by Neil Rickert of
		Northern Illinois University.
	Expand the Return-Path: header at delivery time, after "owner-"
		envelope splitting has occurred.
	Don't try to sort the queue if there are no entries. Patch from
		Luke Mewburn from RMIT University.
	Add a "/quit" command to address test mode.
	Include the proper sender in the UNIX "From " line and Return-Path:
		header when undeliverable mail is saved to ~/dead.letter.
		Problem noted by Kari Hurtta of the Finnish Meteorological
		Institute.
	The contents of a class can now be copied to another class using
		the syntax: "C{Dest} $={Source}".  This would copy all of
		the items in class $={Source} into the class $={Dest}.
	Include original envelope's error transcript in bounces created for
		split (owner-) envelopes to see the original errors when
		the recipients were added.  Based on fix from Motonori
		Nakamura of Kyoto University.
	Show reason for permanent delivery errors directly after the
		addresses.  From Motonori Nakamura of Kyoto University.
	Prevent a segmentation fault when bouncing a split-envelope
		message.  Patch from Motonori Nakamura of Kyoto University.
	If the specification for the queue run interval (-q###) has a
		syntax error, consider the error fatal and exit.
	Pay attention to CheckpointInterval during LMTP delivery.  Problem
		noted by Motonori Nakamura of Kyoto University.
	On operating systems which have setlogin(2), use it to set the
		login name to the RunAsUserName when starting as a daemon.
		This is for delivery to programs which use getlogin().
		Based on fix from Motonori Nakamura of Kyoto University.
	Differentiate between "command not implemented" and "command
		unrecognized" in the SMTP dialogue.
	Strip returns from forward and include files.  Problem noted by
		Allan E Johannesen of Worcester Polytechnic Institute.
	Prevent a core dump when using 'sendmail -bv' on an address which
		resolves to the $#error mailer with a temporary failure.
		Based on fix from Neil Rickert of Northern Illinois
		University.
	Prevent multiple deliveries of a message with a "non-local alias"
		pointing to a local user, if canonicalization fails
		the message was requeued *and* delivered to the alias.
	If an invalid ruleset is declared, the ruleset name could be
		ignored and its rules added to S0.  Instead, ignore the
		ruleset lines as well.
	Avoid incorrect Final-Recipient, Action, and X-Actual-Recipient
		success DSN fields as well as duplicate entries for a
		single address due to S5 and UserDB processing.  Problems
		noted by Kari Hurtta of the Finnish Meteorological
		Institute.
	Turn off timeouts when exiting sendmail due to an interrupt signal
		to prevent the timeout from firing during the exit process.
		Problem noted by Michael Shapiro of Sun Microsystems.
	Do not append @MyHostName to non-RFC822 addresses output by the EXPN
		command or on Final-Recipient: and X-Actual-Recipient: DSN
		headers.  Non-RFC822 addresses include deliveries to
		programs, file, DECnet, etc.
	Fix logic for determining if a local user is using -f or -bs to
		spoof their return address.  Based on idea from Neil Rickert
		of Northern Illinois University and patch from Per Hedeland
		of Ericsson.
	Report the proper UID in the bounce message if an :include: file is
		owned by a uid that doesn't map to a username and the
		:include: file contains delivery to a file or program.
		Problem noted by John Beck of Sun Microsystems.
	Avoid the attempt of trying to send a second SMTP QUIT command if
		the remote server responds to the first QUIT with a 4xx
		response code and drops the connection.  This behavior was
		noted by Ulrich Windl of the Universitat Regensburg when
		sendmail was talking to the Mercury 1.43 MTA.
	If a hostname lookup times out and ServiceSwitchFile is set but the
		file is not present, the lookup failure would be marked as
		a permanent failure instead of a temporary failure.  Fix
		from Russell King of the ARM Linux Project.
	Handle aliases or forwards which deliver to programs using tabs
		instead of spaces between arguments.  Problem noted by Randy
		Wormser.  Fix from Neil Rickert of Northern Illinois
		University.
	Allow MaxRecipientsPerMessage option to be set on the command line
		by normal users (e.g., sendmail won't drop its root
		privileges) to allow overrides for message submission via
		'sendmail -bs'.
	Set the names for help file and statistics file to "helpfile" and
		"statistics", respectively, if no parameters are given for
		them in the .cf file.
	Avoid bogus 'errbody: I/O Error -7' log messages when sending
		success DSN messages for messages relayed to non-DSN aware
		systems.  Problem noted by Juergen Georgi of RUS University
		of Stuttgart and Kyle Tucker of Parexel International.
	Prevent +detail information from interfering with local delivery to
		multiple users in the same transaction (F=m).
	Add H_FORCE flag for the X-Authentication-Warning: header, so it
		will be added even if one already exists.  Problem noted
		by Michal Zalewski of Marchew Industries.
	Stop processing SMTP commands if the SMTP connection is dropped.
		This prevents a remote system from flooding the connection
		with commands and then disconnecting.  Previously, the
		server would process all of the buffered commands.  Problem
		noted by Michal Zalewski of Marchew Industries.
	Properly process user-supplied headers beginning with '?'.  Problem
		noted by Michal Zalewski of Marchew Industries.
	If multiple header checks resolve to the $#error mailer, use the
		last permanent (5XX) failure if any exist.  Otherwise, use
		the last temporary (4XX) failure.
	RFC 1891 requires "hexchar" in a "xtext" to be upper case.  Patch
		from Ronald F. Guilmette of Infinite Monkeys & Co.
	Timeout.ident now defaults to 5 seconds instead of 30 seconds to
		prevent the now common delays associated with mailing to a
		site which drops IDENT packets.  Suggested by many.
	Persistent host status data is not reloaded disk when current data
		is available in the in-memory cache.  Problem noted by Per
		Hedeland of Ericsson.
	mailq displays unprintable characters in addresses as their octal
		representation and a leading backslash.  This avoids problems
		with "unprintable" characters.  Problem noted by Michal
		Zalewski of the "Internet for Schools" project (IdS).
	The mail line length limit (L= equate) was adding the '!' indicator
		one character past the limit.  This would cause subsequent
		hops to break the line again.  The '!' is now placed in
		the last column of the limit if the line needs to be broken.
		Problem noted by Joe Pruett of Q7 Enterprises.  Based on fix
		from Per Hedeland of Ericsson.
	If a resolver ANY query is larger than the UDP packet size, the
		resolver will fall back to TCP.  However, some
		misconfigured firewalls black 53/TCP so the ANY lookup
		fails whereas an MX or A record might succeed.  Therefore,
		don't fail on ANY queries.
	If an SMTP recipient is rejected due to syntax errors in the
		address, do not send an empty postmaster notification DSN
		to the postmaster.  Problem noted by Neil Rickert of
		Northern Illinois University.
	Allow '_' and '.' in map names when parsing a sequence map
		specification.  Patch from William Setzer of North Carolina
		State University.
	Fix hostname in logging of read timeouts for the QUIT command on
		cached connections.  Problem noted by Neil Rickert of
		Northern Illinois University.
	Use a more descriptive entry to log "null" connections, i.e.,
		"host did not issue MAIL/EXPN/VRFY/ETRN during connection".
	Fix a file descriptor leak in ONEX mode.
	Portability:
		Reverse signal handling logic such that sigaction(2) with
			the SA_RESTART flag is the preferred method and the
			other signal methods are only tried if SA_RESTART
			is not available.  Problem noted by Allan E

			Aerospace.
		Hitachi 3050R/3050RX and 3500 Workstations running
			HI-UX/WE2 4.02, 6.10 and 7.10 from Motonori
			NAKAMURA of Kyoto University.
		New compile flag NO_GETSERVBYNAME: set this to disable
			use of getservbyname() on systems which can
			not lookup a service by name over NIS, such as
			HI-UX.  Patch from Motonori NAKAMURA of Kyoto
			University.
		Use devtools/bin/install.sh on SCO 5.x.  Problem noted
			by Sun Wenbing of the China Engineering and
			Technology Information Network.
		make depend didn't work properly on UNIXWARE 4.2.  Problem
			noted by Ariel Malik of Netology, Ltd.
		Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX).
		Set confSTDIO_TYPE to torek for BSD-OS, FreeBSD, NetBSD,
			and OpenBSD.
		A recent Compaq Ultrix 4.5 Y2K patch has broken detection
			of local_hostname_length().  See sendmail/README
			for more details.  Problem noted by Allan E
			Johannesen of Worcester Polytechnic Institute.
	CONFIG: Begin using /etc/mail/ for sendmail related files.  This
		affects a large number of files.  See cf/README for more
		details.
	CONFIG: New macro MAIL_SETTINGS_DIR contains the path (including
		trailing slash) for the mail settings directory.
	CONFIG: Increment version number of config file to 9.
	CONFIG: OSTYPE(`bsdi1.0') and OSTYPE(`bsdi2.0') have been
		deprecated and may be removed from a future release.
		BSD/OS users should begin using OSTYPE(`bsdi').
	CONFIG: OpenBSD 2.4 installs mail.local non-set-user-ID root.  This
		requires a new OSTYPE(`openbsd').  From Todd C. Miller of
		Courtesan Consulting.
	CONFIG: New OSTYPE(`hpux11') for HP/UX 11.X.
	CONFIG: A syntax error in check_mail would cause fake top-level
		domains (.BITNET, .DECNET, .FAX, .USENET, and .UUCP) to
		be improperly rejected as unresolvable.
	CONFIG: New FEATURE(`dnsbl') takes up to two arguments (name of
		DNS server, rejection message) and can be included
		multiple times.
	CONFIG: New FEATURE(`relay_mail_from') allows relaying if the
		mail sender is listed as RELAY in the access map (and tagged
		with From:).
	CONFIG: Optional tagging of LHS in the access map (Connect:,
		From:, To:) to enable finer control.
	CONFIG: New FEATURE(`ldap_routing') implements LDAP address
		routing.  See cf/README for a complete description of the
		new functionality.
	CONFIG: New variables for the new sendmail options:
		confAUTH_MECHANISMS		AuthMechanisms
		confAUTH_OPTIONS		AuthOptions
		confCLIENT_OPTIONS		ClientPortOptions
		confCONTROL_SOCKET_NAME		ControlSocketName
		confDEAD_LETTER_DROP		DeadLetterDrop
		confDEF_AUTH_INFO		DefaultAuthInfo
		confDF_BUFFER_SIZE		DataFileBufferSize
		confLDAP_DEFAULT_SPEC		LDAPDefaultSpec
		confMAX_ALIAS_RECURSION		MaxAliasRecursion
		confMAX_HEADERS_LENGTH		MaxHeadersLength
		confMAX_MIME_HEADER_LENGTH	MaxMimeHeaderLength
		confPID_FILE			PidFile
		confPROCESS_TITLE_PREFIX	ProcessTitlePrefix
		confRRT_IMPLIES_DSN		RrtImpliesDsn
		confTO_CONTROL			Timeout.control
		confTO_RESOLVER_RETRANS		Timeout.resolver.retrans
		confTO_RESOLVER_RETRANS_FIRST	Timeout.resolver.retrans.first
		confTO_RESOLVER_RETRANS_NORMAL	Timeout.resolver.retrans.normal
		confTO_RESOLVER_RETRY		Timeout.resolver.retry
		confTO_RESOLVER_RETRY_FIRST	Timeout.resolver.retry.first
		confTO_RESOLVER_RETRY_NORMAL	Timeout.resolver.retry.normal
		confTRUSTED_USER		TrustedUser
		confXF_BUFFER_SIZE		XscriptFileBufferSize
	CONFIG: confDAEMON_OPTIONS has been replaced by DAEMON_OPTIONS(),
		which takes the options as argument and can be used
		multiple times; see cf/README for details.
	CONFIG: Add a fifth mailer definition to MAILER(`smtp') called
		"dsmtp".  This mail provides on-demand delivery using the
		F=% mailer flag described above.  The "dsmtp" mailer
		definition uses the new DSMTP_MAILER_ARGS which defaults
		to "IPC $h".
	CONFIG: New variables LOCAL_MAILER_MAXMSGS, SMTP_MAILER_MAXMSGS,
		and RELAY_MAILER_MAXMSGS for setting the m= equate for the
		local, smtp, and relay mailers respectively.
	CONFIG: New variable LOCAL_MAILER_DSN_DIAGNOSTIC_CODE for setting
		the DSN Diagnostic-Code type for the local mailer.  The
		value should be changed with care.
	CONFIG: FEATURE(`local_lmtp') now sets the DSN Diagnostic-Code type
		for the local mailer to the proper value of "SMTP".
	CONFIG: All included maps are no longer optional by default; if
		there there is a problem with a map, sendmail will
		complain.
	CONFIG: Removed root from class E; use EXPOSED_USER(`root')
		to get the old behavior.  Suggested by Joe Pruett
		of Q7 Enterprises.
	CONFIG: MASQUERADE_EXCEPTION() defines hosts/subdomains which
		will not be masqueraded.  Proposed by Arne Wichmann
		of MPI Saarbruecken, Griff Miller of PGS Tensor,
		Jayme Cox of Broderbund Software Inc.
	CONFIG: A list of exceptions for FEATURE(`nocanonify') can be
		specified by CANONIFY_DOMAIN or CANONIFY_DOMAIN_FILE,
		i.e., a list of domains which are passed to $[ ... $]
		for canonification. Based on an idea from Neil Rickert
		of Northern Illinois University.
	CONFIG: If `canonify_hosts' is specified as parameter for
		FEATURE(`nocanonify') then addresses which have only
		a hostname, e.g., <user@host>, will be canonified.
	CONFIG: If FEATURE(`nocanonify') is turned on, a trailing dot is
		nevertheless added to addresses with more than one component
		in it.
	CONFIG: Canonification is no longer attempted for any host or domain
		in class 'P' ($=P).
	CONFIG: New class for matching virtusertable entries $={VirtHost} that
		can be populated by VIRTUSER_DOMAIN or VIRTUSER_DOMAIN_FILE.
		FEATURE(`virtuser_entire_domain') can be used to apply this
		class also to entire subdomains.  Hosts in this class are
		treated as canonical in SCanonify2, i.e., a trailing dot
		is added.
	CONFIG: If VIRTUSER_DOMAIN() or VIRTUSER_DOMAIN_FILE() are used,
		include $={VirtHost} in $=R (hosts allowed to relay).
	CONFIG: FEATURE(`generics_entire_domain') can be used to apply the
		genericstable also to subdomains of $=G.
	CONFIG: Pass "+detail" as %2 for virtusertable lookups.
		Patch from Noam Freedman from University of Chicago.
	CONFIG: Pass "+detail" as %1 for genericstable lookups.  Suggested
		by Raymond S Brand of rsbx.net.
	CONFIG: Allow @domain in genericstable to override masquerading.
		Suggested by Owen Duffy from Owen Duffy & Associates.
	CONFIG: LOCAL_DOMAIN() adds entries to class w.  Suggested by Steve
		Hubert of University of Washington.
	CONFIG: OSTYPE(`gnuhurd') has been replaced by OSTYPE(`gnu') as
		GNU is now the canonical system name.  From Mark
		Kettenis of the University of Amsterdam.
	CONFIG: OSTYPE(`unixware7') updates from Larry Rosenman.
	CONFIG: Do not include '=' in option expansion if there is no value
		associated with the option.  From Andrew Brown of
		Graffiti World Wide, Inc.
	CONFIG: Add MAILER(`qpage') to define a new pager mailer.  Contributed
		by Philip A. Prindeville of Enteka Enterprise Technology
		Services.
	CONFIG: MAILER(`cyrus') was not preserving case for mail folder
		names.  Problem noted by Randall Winchester of Swales
		Aerospace.
	CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags
		for the relay mailer.  Suggested by Doug Hughes of Auburn
		University and Brian Candler.
	CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path:
		header) by default.  Suggested by Per Hedeland of Ericsson.
	CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host].
		Suggested by Kari Hurtta of the Finnish Meteorological
		Institute.
	CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS;
		i.e., to set, add, or delete flags.
	CONFIG: If SMTP AUTH is used then relaying is allowed for any user
		who authenticated via a "trusted" mechanism, i.e., one that
		is defined via TRUST_AUTH_MECH(`list of mechanisms').
	CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay
		after check_rcpt and allows for exceptions from the checks.
	CONFIG: Map declarations have been moved into their associated
		feature files to allow greater flexibility in use of
		sequence maps.  Suggested by Per Hedeland of Ericsson.
	CONFIG: New macro LOCAL_MAILER_EOL to override the default end of
		line string for the local mailer.  Requested by Il Oh of
		Willamette Industries, Inc.
	CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is
		converted to <user@d>
	CONFIG: Reject bogus return address of <@@hostname>, generated by
		Sun's older, broken configuration files.
	CONFIG: FEATURE(`nullclient') now provides the full rulesets of a
		normal configuration, allowing anti-spam checks to be
		performed.
	CONFIG: Don't return a permanent error (Relaying denied) if
		${client_name} can't be resolved just temporarily.
		Suggested by Kari Hurtta of the Finnish Meteorological
		Institute.
	CONFIG: Change numbered rulesets into named (which still can
		be accessed by their numbers).
	CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial
		which describes whether to disallow "!" in the local part
		of an address.
	CONFIG: Call Local_localaddr from localaddr (S5) which can be used
		to rewrite an address from a mailer which has the F=5 flag
		set.  If the ruleset returns a mailer, the appropriate
		action is taken, otherwise the returned tokens are ignored.
	CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4
		and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4.
		The latter is kept around for backward compatibility.
	CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries,
		where "D.S.N" is an RFC 1893 compliant error code.
	CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX).
	CONFIG: Remove second space between username and date in UNIX From_
		line.  Noted by Allan E Johannesen of Worcester Polytechnic
		Institute.
	CONFIG: Make sure all of the mailers have complete T= equates.
	CONFIG: Extend FEATURE(`local_procmail') so it can now take
		arguments overriding the mailer program, arguments, and
		mailer definition flags.  This makes it possible to use
		other programs such as maildrop for local delivery.
	CONFIG: Emit warning if FEATURE(`local_lmtp') or
		FEATURE(`local_procmail') is given after MAILER(`local').
		Patch from Richard A. Nelson of IBM.
	CONFIG: Add SMTP Authentication information to Received: header
		default value (confRECEIVED_HEADER).
	CONFIG: Remove `l' flag from USENET_MAILER_FLAGS as it is not a
		local mailer.  Problem noted by Per Hedeland of Ericsson.
	CONTRIB: Added bounce-resender.pl from Brian R. Gaeke of the
		University of California at Berkeley.
	CONTRIB: Added domainmap.m4 from Mark D. Roth of the University of
		Illinois at Urbana-Champaign.
	CONTRIB: etrn.pl now recognizes bogus host names.  Patch from
		Bruce Barnett of GE's R&D Lab.
	CONTRIB: Patches for re-mqueue.pl by Graeme Hewson of Oracle
		Corporation UK.
	CONTRIB: Added qtool.pl to assist in managing the queues.
	DEVTOOLS: Prevent user environment variables from interfering with
		the Build scripts.  Problem noted by Ezequiel H. Panepucci of
		Yale University.
	DEVTOOLS: 'Build -M' will display the obj.* directory which will
		be used for building.
	DEVTOOLS: 'Build -A' will display the architecture that would be
		used for a fresh build.
	DEVTOOLS: New variable confRANLIB, set automatically by configure.sh.
	DEVTOOLS: New variable confRANLIBOPTS for the options to send to
		ranlib.
	DEVTOOLS: 'Build -O <path>' will have the object files build in
		<path>/obj.*.  Suggested by Bryan Costales of Exactis.
	DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the
		building of the man pages when defined.  Suggested by Bryan
		Costales.
	DEVTOOLS: New variables confNO_HELPFILE_INSTALL and
		confNO_STATISTICS_INSTALL which will prevent the
		installation of the sendmail helpfile and statistics file
		respectively.  Suggested by Bryan Costales.
	DEVTOOLS: Recognize ReliantUNIX as SINIX.  Patch from Gerald Rinske
		of Siemens Business Services.
	DEVTOOLS: New variable confSTDIO_TYPE which defines the type of
		stdio library.  The new buffered file I/O depends on the
		Torek stdio library.  This option can be either portable or
		torek.
	DEVTOOLS: New variables confSRCADD and confSMSRCADD which
		correspond to confOBJADD and confSMOBJADD respectively.
		They should contain the C source files for the object files
		listed in confOBJADD and confSMOBJADD.  These file names
		will be passed to the 'make depend' stage of compilation.
	DEVTOOLS: New program specific variables for each of the programs
		in the sendmail distribution.  Each has the form
		`conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'.
		The new variables are conf_prog_ENVDEF, conf_prog_LIBS,
		conf_prog_SRCADD, and conf_prog_OBJADD.
	DEVTOOLS: Build system redesign.  This should have little affect on
		building the distribution, but documentation on the changes
		are in devtools/README.
	DEVTOOLS: Don't allow 'Build -f file' if an object directory already
		exists.  Suggested by Valdis Kletnieks of Virginia Tech.
	DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies
		the path to the sendmail source directory.  confSRCDIR is a
		new variable which identifies the root of the source
		directories for all of the programs in the distribution.
	DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build
		time.  They can both still be overridden by setting the m4
		macro.
	DEVTOOLS: confSBINGRP now defaults to bin instead of kmem.
	DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for
		build configurations, and places objects in obj.prefix.*/.
		Complains as 'Build -f file' does for existing object
		directories.  Suggested by Tom Smith of Digital Equipment
		Corporation.
	DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted
		manual pages in the directory tree specified by
		confMANROOTMAN.
	DEVTOOLS: If formatting the manual pages fails, copy in the
		preformatted pages from the distribution.  The new variable
		confCOPY specifies the copying program.
	DEVTOOLS: Defining confFORCE_RMAIL will install rmail without
		question.  Suggested by Terry Lambert of Whistle
		Communications.
	DEVTOOLS: confSTFILE and confHFFILE can be used to change the names
		of the installed statistics and help files, respectively.
	DEVTOOLS: Remove spaces in `uname -r` output when determining
		operating system identity.  Problem noted by Erik
		Wachtenheim of Dartmouth College.
	DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that
		will be search for the libraries specified in confLIBSEARCH.
		Defaults to "/lib /usr/lib /usr/shlib".
	DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying
		how to strip binaries.  These are used by the new
		install-strip target.
	DEVTOOLS: New config file site.post.m4 which is included after
		the others (if it exists).
	DEVTOOLS: Change order of LIBS: first product specific libraries
		then the default ones.
	MAIL.LOCAL: Will not be installed set-user-ID root.  To use mail.local
		as local delivery agent without LMTP mode, use
		MODIFY_MAILER_FLAGS(`LOCAL', `+S')
		to set the S flag.
	MAIL.LOCAL: Do not reject addresses which would otherwise be
		accepted by sendmail.  Suggested by Neil Rickert of
		Northern Illinois University.
	MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise
		8BITMIME in the LHLO response.  Suggested by Kari Hurtta of
		the Finnish Meteorological Institute.
	MAIL.LOCAL: Add support for the maillock() routines by defining
		MAILLOCK when compiling.  Also requires linking with
		-lmail.  Patch from Neil Rickert of Northern Illinois
		University.
	MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is
		defined when compiling.  Automatically set for Solaris 2.3
		and later.  Patch from Neil Rickert of Northern Illinois
		University.
	MAIL.LOCAL: Move the initialization of the 'notifybiff' address
		structure to the beginning of the program.  This ensures that
		the getservbyname() is done before any seteuid to a possibly
		unauthenticated user.  If you are using NIS+ and secure RPC
		on a Solaris system, this avoids syslog messages such as,
		"authdes_refresh: keyserv(1m) is unable to encrypt session
		key."  Patch from Neil Rickert of Northern Illinois
		University.
	MAIL.LOCAL: Support group writable mail spool files when MAILGID is
		set to the gid to use (-DMAILGID=6) when compiling.
		Patch from Neil Rickert of Northern Illinois University.
	MAIL.LOCAL: When a mail message included lines longer than 2046
		characters (in LMTP mode), mail.local split the incoming
		line up into 2046-character output lines (excluding the
		newline).  If an input line was 2047 characters long
		(excluding CR-LF) and the last character was a '.',
		mail.local saw it as the end of input, transfered it to the
		user mailbox and tried to write an `ok' back to sendmail.
		If the message was much longer, both sendmail and
		mail.local would deadlock waiting for each other to read
		what they have written.  Problem noted by Peter Jeremy of
		Alcatel Australia Limited.
	MAIL.LOCAL: New option -b to return a permanent error instead of a
		temporary error if a mailbox exceeds quota.  Suggested by
		Neil Rickert of Northern Illinois University.
	MAIL.LOCAL: The creation of a lockfile is subject to a global
		timeout to avoid starvation.
	MAIL.LOCAL: Properly parse addresses with multiple quoted
		local-parts.  Problem noted by Ronald F. Guilmette of
		Infinite Monkeys & Co.
	MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR.
	MAILSTATS: New -p option to invoke program mode in which stats are
		printed in a machine readable fashion and the stats file
		is reset.  Patch from Kevin Hildebrand of the University
		of Maryland.
	MAKEMAP: If running as root, automatically change the ownership of
		generated maps to the TrustedUser as specified in the
		sendmail configuration file.
	MAKEMAP: New -C option to accept an alternate sendmail
		configuration file to use for finding the TrustedUser
		option.
	MAKEMAP: New -u option to dump (unmap) a database.  Based on
		code contributed by Roy Mongiovi of Georgia Tech.
	MAKEMAP: New -e option to allow empty values.  Suggested by Philip
		A. Prindeville of Enteka Enterprise Technology Services.
	MAKEMAP: Compile cleanly on 64-bit operating systems.  Problem
		noted by Gerald Rinske of Siemens Business Services.
	OP.ME: Correctly document interaction between F=S and U= mailer
		equates.  Problem noted by Bob Halley of Internet Engines.
	OP.ME: Fixup Timeout documentation.  From Graeme Hewson of Oracle
		Corporation UK.
	OP.ME: The Timeout [r] option was incorrectly listed as "safe"
		(e.g., sendmail would not drop root privileges if the
		option was specified on the command line).  Problem noted
		by Todd C. Miller of Courtesan Consulting.
	PRALIASES: Handle the hash and btree map specifications for
		Berkeley DB.  Patch from Brian J. Coan of the
		Institute for Global Communications.
	PRALIASES: Read the sendmail.cf file for the location(s) of the
		alias file(s) if the -f option is not used.  Patch from
		John Beck of Sun Microsystems.
	PRALIASES: New -C option to specify an alternate sendmail
		configuration file to use for finding alias file(s).  Patch
		from John Beck of Sun Microsystems.
	SMRSH: allow shell commands echo, exec, and exit.  Allow command
		lists using || and &&.  Based on patch from Brian J. Coan
		of the Institute for Global Communications.
	SMRSH: Update README for the new Build system.  From Tim Pierce
		of RootsWeb Genealogical Data Cooperative.
	VACATION: Added vacation auto-responder to sendmail distribution.
	LIBSMDB: Added abstracted database library.  Works with Berkeley
		DB 1.85, Berkeley DB 2.X, Berkeley DB 3.X, and NDBM.
	Changed Files:
		The Build script in the various program subdirectories are
			no longer symbolic links.  They are now scripts
			which execute the actual Build script in
			devtools/bin.
		All the manual pages are now written against -man and not
			-mandoc as they were previously.
		Add a simple Makefile to every directory so make instead
			of Build will work (unless parameters are
			required for Build).

8.9.3/8.9.3	1999/02/04
	SECURITY: Limit message headers to a maximum of 32K bytes (total
		of all headers in a single message) to prevent a denial of
		service attack.  This limit will be configurable in 8.10.
		Problem noted by Michal Zalewski of the "Internet for
		Schools" project (IdS).
	Prevent segmentation fault on an LDAP lookup if the LDAP map
		was closed due to an earlier failure.  Problem noted by
		Jeff Wasilko of smoe.org.  Fix from Booker Bense of
		Stanford University and Per Hedeland of Ericsson.
	Preserve the order of the MIME headers in multipart messages
		when performing the MIME header length check.  This
		will allow PGP signatures to function properly.  Problem
		noted by Lars Hecking of University College, Cork, Ireland.
	If ruleset 5 rewrote the local address to an :include: directive,
		the delivery would fail with an "aliasing/forwarding loop
		broken" error.  Problem noted by Eric C Hagberg of Morgan
		Stanley.  Fix from Per Hedeland of Ericsson.
	Allow -T to work for bestmx maps.  Fix from Aaron Schrab of
		ExecPC Internet Systems.
	During the transfer of a message in an SMTP transaction, if a
		TCP timeout occurs, the message would be properly queued
		for later retry but the failure would be logged as
		"Illegal Seek" instead of a timeout.  Problem noted by
		Piotr Kucharski of the Warsaw School of Economics (SGH)
		and Carles Xavier Munyoz Baldo of CTV Internet.
	Prevent multiple deliveries on a self-referencing alias if the
		F=w mailer flag is not set.  Problem noted by Murray S.
		Kucherawy of Concentric Network Corporation and Per
		Hedeland of Ericsson.
	Do not strip empty headers but if there is no value and a
		default is defined in sendmail.cf, use the default.
		Problem noted by Philip Guenther of Gustavus Adolphus
		College and Christopher McCrory of Netus, Inc.
	Don't inherit information about the sender (notably the full name)
		in SMTP (-bs) mode, since this might be called from inetd.
	Accept any 3xx reply code in response to DATA command instead of
		requiring 354.  This change will match the wording to be
		published in the updated SMTP specification from the DRUMS
		group of the IETF.
	Portability:
		AIX 4.2.0 or 4.2.1 may become updated by the fileset
			bos.rte.net level 4.2.0.2.  This introduces the
			softlink /usr/lib/libbind.a which should
			not be used.  It conflicts with the resolver
			built into libc.a.  "bind" has been removed
			from the confLIBSEARCH BuildTools variable.
			Users who have installed BIND 8.X will have
			to add it back in their site.config.m4 file.
			Problem noted by Ole Holm Nielsen of the
			Technical University of Denmark.
		CRAY TS 10.0.x from Sven Nielsen of San Diego
			Supercomputer Center.
		Improved LDAP version 3 integration based on input
			from Kurt D. Zeilenga of the OpenLDAP Foundation,
			John Beck of Sun Microsystems, and Booker Bense
			of Stanford University.
		Linux doesn't have a standard way to get the timezone
			between different releases.  Back out the
			change in 8.9.2 and don't attempt to derive
			a timezone.  Problem reported by Igor S. Livshits
			of the University of Illinois at Urbana-Champaign
			and Michael Dickens of Tetranet Communications.
		Reliant UNIX, the new name for SINIX, from Gert-Jan Looy
			of Siemens/SNI.
		SunOS 5.8 from John Beck of Sun Microsystems.
	CONFIG: SCO UnixWare 2.1 and 7.0 need TZ to get the proper
		timezone.  Problem noted by Petr Lampa of Technical
		University of Brno.
	CONFIG: Handle <@bestmx-host:user@otherhost> addressing properly
		when using FEATURE(bestmx_is_local).  Patch from Neil W.
		Rickert of Northern Illinois University.
	CONFIG: Properly handle source routed and %-hack addresses on
		hosts which the mailertable remaps to local:.  Patch from
		Neil W. Rickert of Northern Illinois University.
	CONFIG: Internal fixup of mailertable local: map value.  Patch from
		Larry Parmelee of Cornell University.
	CONFIG: Only add back +detail from host portion of mailer triplet
		on local mailer triplets if it was originally +detail.
		Patch from Neil W. Rickert of Northern Illinois University.

	SECURITY: Remove five second sleep on accepting daemon connections
		due to an accept() failure.  This sleep could be used
		for a denial of service attack.
	Do not silently ignore queue files with names which are too long.
		Patch from Bryan Costales of InfoBeat, Inc.
	Do not store failures closing an SMTP session in persistent
		host status.  Reported by Graeme Hewson of Oracle
		Corporation UK.
	Allow symbolic link forward files if they are in safe directories.
		Problem noted by Andreas Schott of the Max Planck Society.
	Missing columns in a text map could cause a segmentation fault.
		Fix from David Lee of the University of Durham.
	Note that for 8.9.X, PrivacyOptions=goaway also includes the
		noetrn flag.  This is scheduled to change in a future
		version of sendmail.  Problem noted by Theo Van Dinter of
		Chrysalis Symbolic Designa and Alan Brown of Manawatu
		Internet Services.
	When trying to do host canonification in a Wildcard MX
		environment, try an MX lookup of the hostname without the
		default domain appended.  Problem noted by Olaf Seibert of
		Polderland Language & Speech Technology.
	Reject SMTP RCPT To: commands with only comments (i.e.
		'RCPT TO: (comment)'.  Problem noted by Earle Ake of
		Hassler Communication Systems Technology, Inc.
	Handle any number of %s in the LDAP filter spec.  Patch from
		Per Hedeland of Ericsson.
	Clear ldapx open timeouts even if the map open failed to prevent
		a segmentation fault.  Patch from Wayne Knowles of the
		National Institute of Water & Atmospheric Research Ltd.
	Do not syslog envelope clone messages when using address
		verification (-bv).  Problem noted by Kari Hurtta of the
		Finnish Meteorological Institute.
	Continue to perform queue runs while in daemon mode even if the
		daemon is rejecting connections due to a disk full
		condition.  Problem noted by JR Oldroyd of TerraNet
		Internet Services.
	Include full filename on installation of the sendmail.hf file
		in case the $HFDIR directory does not exist.  Problem
		noted by Josef Svitak of Montana State University.
	Close all maps when exiting the process with one exception.
		Berkeley DB can use internal shared memory locking for
		its memory pool.  Closing a map opened by another process
		will interfere with the shared memory and locks of the
		parent process leaving things in a bad state.  For
		Berkeley DB, only close the map if the current process
		is also the one that opened the map, otherwise only close
		the map file descriptor.  Thanks to Yoseff Francus of
		Collective Technologies for volunteering his system for
		extended testing.
	Avoid null pointer dereference on XDEBUG output for SMTP reply
		failures.  Problem noted by Carlos Canau of EUnet Portugal.
	On mailq and hoststat listings being piped to another program, such
		as more, if the pipe closes (i.e., the user quits more),
		stop sending output and exit.  Patch from Allan E Johannesen
		of Worcester Polytechnic Institute.
	In accordance with the documentation, LDAP map lookup failures
		are now considered temporary failures instead of permanent
		failures unless the -t flag is used in the map definition.
		Problem noted by Booker Bense of Stanford University and
		Eric C. Hagberg of Morgan Stanley.
	Fix by one error reporting on long alias names.  Problem noted by
		H. Paul Hammann of the Missouri Research and Education
		Network.
	Fix DontBlameSendmail=IncludeFileInUnsafeDirPath behavior.  Problem
		noted by Barry S. Finkel of Argonne National Laboratory.
	When automatically converting from 8 bit to quoted printable MIME,
		be careful not to miss a multi-part boundary if that
		boundary is preceded by a boundary-like line.  Problem
		noted by Andreas Raschle of Ansid Inc.  Fix from
		Kari Hurtta of the Finnish Meteorological Institute.
	Avoid bogus reporting of "LMTP tobuf overflow" when the buffer
		has enough space for the additional address.  Problem
		noted by Steve Cliffe of the University of Wollongong.
	Fix DontBlameSendmail=FileDeliveryToSymlink behavior.  Problem
		noted by Alex Vorobiev of Swarthmore College.
	If the check_compat ruleset resolves to the $#discard mailer,
		discard the current recipient.  Unlike check_relay,
		check_mail, and check_rcpt, the entire envelope is not
		discarded.  Problem noted by RZ D. Rahlfs.  Fix from
		Claus Assmann of Christian-Albrechts-University of Kiel.
	Avoid segmentation fault when reading ServiceSwitchFile files with
		bogus formatting.  Patch from Kari Hurtta of the Finnish
		Meteorological Institute.
	Support Berkeley DB 2.6.4 API change.

	If the check_relay ruleset resolved to the discard mailer, messages
		were still delivered.  Problem noted by Mirek Luc of NASK.
	Mail delivery to files would fail with an Operating System Error
		if sendmail was not running as root, i.e., RunAsUser was set.
		Problem noted by Leonard N. Zubkoff of Dandelion Digital.
	Prevent MinQueueAge from interfering from queued items created

8.9.0/8.9.0	1998/05/19
	SECURITY: To prevent users from reading files not normally
		readable, sendmail will no longer open forward, :include:,
		class, ErrorHeader, or HelpFile files located in unsafe
		(i.e., group or world writable) directory paths.  Sites
		which need the ability to override security can use the
		DontBlameSendmail option.  See the README file for more
		information.
	SECURITY: Problems can occur on poorly managed systems, specifically,
		if maps or alias files are in world writable directories.
		This fixes the change added to 8.8.6 to prevent links in these
		world writable directories.
	SECURITY: Make sure ServiceSwitchFile option file is not a link if
		it is in a world writable directory.
	SECURITY: Never pass a tty to a mailer -- if a mailer can get at the
		tty it may be able to push bytes back to the senders input.
		Unfortunately this breaks -v mode.  Problem noted by
		Wietse Venema of the Global Security Analysis Lab at
		IBM T.J. Watson Research.
	SECURITY: Empty group list if DontInitGroups is set to true to
		prevent program deliveries from picking up extra group
		privileges.  Problem reported by Wolfgang Ley of DFN-CERT.
	SECURITY: The default value for DefaultUser is now set to the uid and
		gid of the first existing user mailnull, sendmail, or daemon
		that has a non-zero uid.  If none of these exist, sendmail
		reverts back to the old behavior of using uid 1 and gid 1.
		This is a security problem for Linux which has chosen that
		uid and gid for user bin instead of daemon.  If DefaultUser
		is set in the configuration file, that value overrides this
		default.
	SECURITY: Since 8.8.7, the check for non-set-user-ID binaries
		interfered with setting an alternate group id for the
		RunAsUser option.  Problem noted by Randall Winchester of
		the University of Maryland.
	Add support for Berkeley DB 2.X.  Based on patch from John Kennedy
		of Cal State University, Chico.
	Remove support for OLD_NEWDB (pre-1.5 version of Berkeley DB).  Users
		which previously defined OLD_NEWDB=1 must now upgrade to the
		current version of Berkeley DB.
	Added support for regular expressions using the new map class regex.
		From Jan Krueger of Unix-AG of University of Hannover.
	Support for BIND 8.1.1's hesiod for hesiod maps and hesiod
		UserDatabases from Randall Winchester of the University
		of Maryland.
	Allow any shell for user shell on program deliveries on V1
		configurations for backwards compatibility on machines which
		do not have getusershell().  Fix from John Beck of Sun
		Microsystems.
	On operating systems which change the process title by reusing the
		argument vector memory, sendmail could corrupt memory if the
		last argument was either "-q" or "-d".  Problem noted by
		Frank Langbein of the University of Stuttgart.
	Support Local Mail Transfer Protocol (LMTP) between sendmail and
		mail.local on the F=z flag.
	Macro-expand the contents of the ErrMsgFile.  Previously this was
		only done if you had magic characters (0x81) to indicate
		macro expansion.  Now $x will be expanded.  This means that
		real dollar signs have to be backslash escaped.
	TCP Wrappers expects "unknown" in the hostname argument if the
		reverse DNS lookup for the incoming connection fails.
		Problem noted by Randy Grimshaw of Syracuse University and
		Wietse Venema of the Global Security Analysis Lab at
		IBM T.J. Watson Research.
	DSN success bounces generated from an invocation of sendmail -t
		would be sent to both the sender and MAILER-DAEMON.
		Problem noted by Claus Assmann of
		Christian-Albrechts-University of Kiel.
	Avoid "Error 0" messages on delivery mailers which exit with a
		valid exit value such as EX_NOPERM.  Fix from Andreas Luik
		of ISA Informationssysteme GmbH.
	Tokenize $&x expansions on right hand side of rules.  This eliminates
		the need to use tricks like $(dequote "" $&{client_name} $)
		to cause the ${client_name} macro to be properly tokenized.
	Add the MaxRecipientsPerMessage option: this limits the number of
		recipients that will be accepted in a single SMTP
		transaction.  After this number is reached, sendmail
		starts returning "452 Too many recipients" to all RCPT
		commands.  This can be used to limit the number of recipients
		per envelope (in particular, to discourage use of the server
		for spamming).  Note: a better approach is to restrict
		relaying entirely.
	Fixed pointer initialization for LDAP lmap struct, fixed -s option
		to ldapx map and added timeout for ldap_open call to
		avoid hanging sendmail in the event of hung LDAP servers.
		Patch from Booker Bense of Stanford University.
	Allow multiple -qI, -qR, or -qS queue run limiters.  For example,
		'-qRfoo -qRbar' would deliver mail to recipients with foo or
		bar in their address.  Patch from Allan E Johannesen of
		Worcester Polytechnic Institute.
	The bestmx map will now return a list of the MX servers for a host if
		passed a column delimiter via the -z map flag.  This can be
		used to check if the server is an MX server for the recipient
		of a message.  This can be used to help prevent relaying.
		Patch from Mitchell Blank Jr of Exec-PC.
	Mark failures for the *file* mailer and return bounce messages to the
		sender for those failures.
	Prevent bogus syslog timestamps on errors in sendmail.cf by
		preserving the TZ environment variable until TimeZoneSpec
		has been determined.  Problem noted by Ralf Hildebrandt of
		Technical University of Braunschweig.  Patch from Per Hedeland
		of Ericsson.
	Print test input in address test mode when input is not from the tty
		when the -v flag is given (i.e., sendmail -bt -v) to make
		output easier to decipher.  Problem noted by Aidan Nichol
		of Procter & Gamble.
	The LDAP map -s flag was not properly parsed and the error message
		given included the remainder of the arguments instead of
		solely the argument in error.  Problem noted by Aidan Nichol
		of Procter & Gamble.
	New DontBlameSendmail option.  This option allows administrators to
		bypass some of sendmail's file security checks at the expense
		of system security.  This should only be used if you are
		absolutely sure you know the consequences.  The available
		DontBlameSendmail options are:
			Safe
			AssumeSafeChown
			ClassFileInUnsafeDirPath
			ErrorHeaderInUnsafeDirPath
			GroupWritableDirPathSafe

	New DontProbeInterfaces option to turn off the inclusion of all the
		interface names in $=w on startup.  In particular, if you
		have lots of virtual interfaces, this option will speed up
		startup.  However, unless you make other arrangements, mail
		sent to those addresses will be bounced.
	Automatically create alias databases if they don't exist and
		AutoRebuildAliases is set.
	Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command.
		Suggested by Christophe Wolfhugel of the Institut Pasteur.
	Add PrivacyOptions=noverb flag to disable the SMTP VERB command.
	When determining the client host name ($&{client_name} macro), do
		a forward (A) DNS lookup on the result of the PTR lookup
		and compare results.  If they differ or if the PTR lookup
		fails, &{client_name} will contain the IP address
		surrounded by square brackets (e.g., [127.0.0.1]).
	New map flag: -Tx appends "x" to lookups that return temporary failure
		(i.e, it is like -ax for the temporary failure case, in
		contrast to the success case).
	New syntax to do limited checking of header syntax.  A config line
		of the form:
			HHeader: $>Ruleset
		causes the indicated Ruleset to be invoked on the Header
		when read.  This ruleset works like the check_* rulesets --
		that is, it can reject mail on the basis of the contents.
	Limit the size of the HELO/EHLO parameter to prevent spammers
		from hiding their connection information in Received:
		headers.
	When SingleThreadDelivery is active, deliveries to locked hosts
		are skipped.  This will cause the delivering process to
		try the next MX host or queue the message if no other MX
		hosts are available.  Suggested by Alexander Litvin.
	The [FILE] mailer type now delivers to the file specified in the
		A= equate of the mailer definition instead of $u.  It also
		obeys all of the F= mailer flags such as the MIME
		7/8 bit conversion flags.  This is useful for defining
		a mailer which delivers to the same file regardless of the
		recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail).
	Do not assume the identity of a remote connection is root@localhost
		if the remote connection closes the socket before the
		remote identity can be queried.
	Change semantics of the F=S mailer flag back to 8.7.5 behavior.
		Some mailers, including procmail, require that the real
		uid is left unchanged by sendmail.  Problem noted by Per
		Hedeland of Ericsson.
	No longer is the src/obj*/Makefile selected from a large list -- it
		is now generated using the information in BuildTools/OS/ --
		some of the details are determined dynamically via
		BuildTools/bin/configure.sh.
	The other programs in the sendmail distribution -- mail.local,
		mailstats, makemap, praliases, rmail, and smrsh -- now use
		the new Build method which creates an operating system
		specific Makefile using the information in BuildTools.
	Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e.,
		a failure on one message won't affect future messages to the
		same host).  This is necessary if the remote host sends
		a 451 error if the domain of the sender does not resolve
		as is common in anti-spam configurations.  Problem noted
		by Mitchell Blank Jr of Exec-PC.
	New "discard" mailer for check_* rulesets and header checking
		rulesets.  If one of the above rulesets resolves to the
		$#discard mailer, the commands will be accepted but the
		message will be completely discarded after it is accepting.
		This means that even if only one of the recipients
		resolves to the $#discard mailer, none of the recipients
		will receive the mail.  Suggested by Brian Kantor.
	All but the last cloned envelope of a split envelope were queued
		instead of being delivered.  Problem noted by John Caruso
		of CNET: The Computer Network.
	Fix deadlock situation in persistent host status file locking.
	Syslog an error if a user forward file could not be read due to
		an error.  Patch from John Beck of Sun Microsystems.
	Use the first name returned on machine lookups when canonifying a
		hostname via NetInfo.  Patch from Timm Wetzel of GWDG.
	Clear the $&{client_addr}, $&{client_name}, and $&{client_port}
		macros when delivering a bounce message to prevent
		rejection by a check_compat ruleset which uses these macros.
		Problem noted by Jens Hamisch of AgiX Internetservices GmbH.
	If the check_relay ruleset resolves to the the error mailer, the
		error in the $: portion of the resolved triplet is used
		in the rejection message given to the remote machine.
		Suggested by Scott Gifford of The Internet Ramp.
	Set the $&{client_addr}, $&{client_name}, and $&{client_port} macros
		before calling the check_relay ruleset.  Suggested by Scott
		Gifford of The Internet Ramp.
	Sendmail would get a segmentation fault if a mailer exited with an
		exit code of 79.  Problem noted by Aaron Schrab of ExecPC
		Internet.  Fix from Christophe Wolfhugel of the Pasteur
		Institute.
	Separate snprintf/vsnprintf routines into separate file for use by
		mail.local.
	Allow multiple map lookups on right hand side, e.g.,
		R$*	$( host $1 $) $| $( passwd $1 $).  Patch from
		Christophe Wolfhugel of the Pasteur Institute.
	Properly generate success DSN messages if requested for aliases
		which have owner- aliases.  Problem noted by Kari Hurtta
		of the Finnish Meteorological Institute.
	Properly display delayed-expansion macros ($&{macroname}) in
		address test mode (-bt).  Problem noted by Bryan Costales
		of InfoBeat, Inc.
	-qR could sometimes match names incorrectly.  Problem noted by
		Lutz Euler of Lavielle EDV Systemberatung GmbH & Co.
	Include a magic number and version in the StatusFile for the
		mailstats command.
	Record the number of rejected and discarded messages in the
		StatusFile for display by the mailstats command.  Patch
		from Randall Winchester of the University of Maryland.
	IDENT returns where the OSTYPE field equals "OTHER" now list the
		user portion as IDENT:username@site instead of
		username@site to differentiate the two.  Suggested by
		Kari Hurtta of the Finnish Meteorological Institute.
	Enforce timeout for LDAP queries.  Patch from Per Hedeland of
		Ericsson.
	Change persistent host status filename substitution so '/' is
		replaced by ':' instead of '|' to avoid clashes.  Also
		avoid clashes with hostnames with leading dots.  Fix from
		Mitchell Blank Jr. of Exec-PC.
	If the system lock table is full, only attempt to create a new
		queue entry five times before giving up.  Previously, it
		was attempted indefinitely which could cause the partition
		to run out of inodes.  Problem noted by Suzie Weigand of
		Stratus Computer, Inc.
	In verbose mode, warn if the sendmail.cf version is less than the
		currently supported version.
	Sorting for QueueSortOrder=host is now case insensitive.  Patch
		from Randall S. Winchester of the University of Maryland.
	Properly quote a full name passed via the -F command line option,
		the Full-Name: header, or the NAME environment variable if
		it contains characters which must be quoted.  Problem noted
		by Kari Hurtta of the Finnish Meteorological Institute.
	Avoid possible race condition that unlocked a mail job before
		releasing the transcript file on systems that use flock(2).
		In some cases, this might result in a "Transcript Unavailable"
		message in error bounces.
	Accept SMTP replies which contain only a reply code and no
		accompanying text.  Problem noted by Fernando Fraticelli of
		Digital Equipment Corporation.
	Portability:

		IRIX 6.X load average code from Bob Mende of SGI.
		QNX from Glen McCready <glen@qnx.com>.
		SCO 4.2 and 5.x use /usr/bin instead of /usr/ucb for links

			as kmem does not exist.  From Guillermo Freige of
			Gobernacion de la Pcia de Buenos Aires and Paul
			Fischer of BTG, Inc.
		SunOS 4.X does not include memmove().  Patch from
			Per Hedeland of Ericsson.
		SunOS 5.7 includes getloadavg() function for determining
			load average.  Patch from John Beck of Sun
			Microsystems.
	CONFIG: Increment version number of config file.
	CONFIG: add DATABASE_MAP_TYPE to set the default type of database
		map for the various maps.  The default is hash.  Patch from
		Robert Harker of Harker Systems.
	CONFIG: new confEBINDIR m4 variable for defining the executable
		directory for certain programs.
	CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for
		local mail delivery.  By the default, /usr/libexec/mail.local
		is used.  This is expected to be the mail.local shipped
		with 8.9 which is LMTP capable.  The path is based on the
		new confEBINDIR m4 variable.
	CONFIG: Use confEBINDIR in determining path to smrsh for
		FEATURE(smrsh).  Note that this changes the default from
		/usr/local/etc/smrsh to /usr/libexec/smrsh.  To obtain the
		old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh).
	CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to
		include $z/.forward.$w+$h and $z/.forward+$h which allow
		the user to setup different .forward files for
		user+detail addressing.
	CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES,
		and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage,
		DontProbeInterfaces, and DontBlameSendmail options.
	CONFIG: by default do not allow relaying (that is, accepting mail
		from outside your domain and sending it to another host
		outside your domain).
	CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from
		any site to any site.
	CONFIG: new FEATURE(relay_entire_domain) allows any host in your
		domain as defined by the 'm' class ($=m) to relay.
	CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on
		the MX records of the host portion of an incoming recipient.
	CONFIG: new FEATURE(access_db) which turns on the access database
		feature.  This database gives you the ability to allow
		or refuse to accept mail from specified domains for
		administrative reasons.  By default, names that are listed
		as "OK" in the access db are domain names, not host names.
	CONFIG: new confCR_FILE m4 variable for defining the name of the file
		used for class 'R'.  Defaults to /etc/mail/relay-domains.
	CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file)
		to add items to class 'R' ($=R) for hosts allowed to relay.
	CONFIG: new FEATURE(relay_hosts_only) to change the behavior
		of FEATURE(access_db) and class 'R' to lookup individual
		host names only.
	CONFIG: new FEATURE(loose_relay_check).  Normally, if a recipient
		using % addressing is used, e.g.  user%site@othersite,
		and othersite is in class 'R', the check_rcpt ruleset
		will strip @othersite and recheck user@site for relaying.
		This feature changes that behavior.  It should not be
		needed for most installations.
	CONFIG: new FEATURE(relay_local_from) to allow relaying if the
		domain portion of the mail sender is a local host.  This
		should only be used if absolutely necessary as it opens
		a window for spammers.  Patch from Randall S. Winchester of
		the University of Maryland.
	CONFIG: new FEATURE(blacklist_recipients) turns on the ability to
		block incoming mail destined for certain recipient
		usernames, hostnames, or addresses.
	CONFIG: By default, MAIL FROM: commands in the SMTP session will be
		refused if the host part of the argument to MAIL FROM: cannot
		be located in the host name service (e.g., DNS).
	CONFIG: new FEATURE(accept_unresolvable_domains) accepts
		unresolvable hostnames in MAIL FROM: SMTP commands.
	CONFIG: new FEATURE(accept_unqualified_senders) accepts
		MAIL FROM: senders which do not include a domain.
	CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the
		Realtime Blackhole List.  You can specify the RBL name
		server to contact by specifying it as an optional argument.
		The default is rbl.maps.vix.com.  For details, see
		http://maps.vix.com/rbl/.
	CONFIG: Call Local_check_relay, Local_check_mail, and
		Local_check_rcpt from check_relay, check_mail, and
		check_rcpt.  Users with local rulesets should place the
		rules using LOCAL_RULESETS.  If a Local_check_* ruleset
		returns $#OK, the message is accepted.  If the ruleset
		returns a mailer, the appropriate action is taken, else
		the return of the ruleset is ignored.
	CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by
		default to support file, :include:, and program deliveries.
	CONFIG: Remove the default for confDEF_USER_ID so the binary can
		pick the proper default value.  See the SECURITY note
		above for more information.
	CONFIG: FEATURE(nodns) now warns the user that the feature is a
		no-op.  Patch from Kari Hurtta of the Finnish
		Meteorological Institute.
	CONFIG: OSTYPE(osf1) now sets DefaultUserID (confDEF_USER_ID) to
		daemon since DEC's /bin/mail will drop the envelope
		sender if run as mailnull.  See the Digital UNIX section
		of src/README for more information.  Problem noted by
		Kari Hurtta of the Finnish Meteorological Institute.
	CONFIG: .cf files are now stored in the same directory with the
		.mc files instead of in the obj directory.
	CONFIG: New options confSINGLE_LINE_FROM_HEADER,
		confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for
		setting SingleLineFromHeader, AllowBogusHELO, and
		MustQuoteChars respectively.
	MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout.  This
		SMTP-like protocol allows detailed reporting of delivery
		status on a per-user basis.  Code donated by John Myers of
		CMU (now of Netscape).
	MAIL.LOCAL: HP-UX support from Randall S. Winchester of the
		University of Maryland.  NOTE: mail.local is not
		compatible with the stock HP-UX mail format.  Be sure to
		read mail.local/README.
	MAIL.LOCAL: Prevent other mail delivery agents from stealing a
		mailbox lock.  Patch from Randall S. Winchester of the
		University of Maryland.
	MAIL.LOCAL: glibc portability from John Kennedy of Cal State
		University, Chico.
	MAIL.LOCAL: IRIX portability from Kari Hurtta of the Finnish
		Meteorological Institute.
	MAILSTATS: Display the number of rejected and discarded messages
		in the StatusFile.  Patch from Randall Winchester of the
		University of Maryland.
	MAKEMAP: New -s flag to ignore safety checks on database map files
		such as linked files in world writable directories.
	MAKEMAP: Add support for Berkeley DB 2.X.  Remove OLD_NEWDB support.
	PRALIASES: Add support for Berkeley DB 2.X.
	PRALIASES: Do not automatically include NDBM support.  Problem
		noted by Ralf Hildebrandt of the Technical University of
		Braunschweig.
	RMAIL: Improve portability for other platforms.  Patches from
		Randall S. Winchester of the University of Maryland and
		Kari Hurtta of the Finnish Meteorological Institute.

8.8.8/8.8.8	1997/10/24
	If the check_relay ruleset failed, the relay= field was logged
		incorrectly.  Problem noted by Kari Hurtta of the Finnish
		Meteorological Institute.
	If /usr/tmp/dead.letter already existed, sendmail could not
		add additional bounces to it.  Problem noted by Thomas J.
		Arseneault of SRI International.
	If an SMTP mailer used a non-standard port number for the outgoing
		connection, it would be displayed incorrectly in verbose mode.
		Problem noted by John Kennedy of Cal State University, Chico.
	Log the ETRN parameter specified by the client before altering them
		to internal form.  Suggested by Bob Kupiec of GES-Verio.
	EXPN and VRFY SMTP commands on malformed addresses were logging as
		User unknown with bogus delay= values.  Change them to log
		the same as compliant addresses.  Problem noted by Kari E.
		Hurtta of the Finnish Meteorological Institute.
	Ignore the debug resolver option unless using sendmail debug trace
		option for resolver.  Problem noted by Greg Nichols of Wind
		River Systems.
	If SingleThreadDelivery was enabled and the remote server returned a
		protocol error on the DATA command, the connection would be
		closed but the persistent host status file would not be
		unlocked so other sendmail processes could not deliver to
		that host.  Problem noted by Peter Wemm of DIALix.
	If queueing up a message due to an expensive mailer, don't increment
		the number of delivery attempts or set the last delivery
		attempt time so the message will be delivered on the next
		queue run regardless of MinQueueAge.  Problem noted by
		Brian J. Coan of the Institute for Global Communications.
	Authentication warnings of "Processed from queue _directory_" and
		"Processed by _username_ with -C _filename_" would be logged
		with the incorrect timestamp.  Problem noted by Kari E. Hurtta
		of the Finnish Meteorological Institute.
	Use a better heuristic for detecting GDBM.
	Log null connections on dropped connections.  Problem noted by
		Jon Lewis of Florida Digital Turnpike.
	If class dbm maps are rebuilt, sendmail will now detect this and
		reopen the map.  Previously, they could give stale
		results during a single message processing (but would
		recover when the next message was received).  Fix from
		Joe Pruett of Q7 Enterprises.
	Do not log failures such as "User unknown" on -bv or SMTP VRFY
		requests.  Problem noted by Kari E. Hurtta of the
		Finnish Meteorological Institute.
	Do not send a bounce message back to the sender regarding bad
		recipients if the SMTP connection is dropped before the
		message is accepted.  Problem noted by Kari E. Hurtta of the
		Finnish Meteorological Institute.
	Use "localhost" instead of "[UNIX: localhost]" when connecting to
		sendmail via a UNIX pipe.  This will allow rulesets using
		$&{client_name} to process without sending the string through
		dequote.  Problem noted by Alan Barrett of Internet Africa.
	A combination of deferred delivery mode, a double bounce situation,
		and the inability to save a bounce message to
		/var/tmp/dead.letter would cause sendmail to send a bounce
		to postmaster but not remove the offending envelope from the
		queue causing it to create a new bounce message each time the
		queue was run.  Problem noted by Brad Doctor of Net Daemons
		Associates.
	Remove newlines from hostname information returned via DNS.  There are
		no known security implications of newlines in hostnames as
		sendmail filters newlines in all vital areas; however, this
		could cause confusing error messages.
	Starting with sendmail 8.8.6, mail sent with the '-t' option would be
		rejected if any of the specified addresses were bad.  This
		behavior was modified to only reject the bad addresses and not
		the entire message.  Problem noted by Jozsef Hollosi of
		SuperNet, Inc.
	Use Timeout.fileopen when delivering mail to a file.  Suggested by
		Bryan Costales of InfoBeat, Inc.
	Display the proper Final-Recipient on DSN messages for non-SMTP
		mailers.  Problem noted by Kari E. Hurtta of the
		Finnish Meteorological Institute.
	An error in calculating the available space in the list of addresses
		for logging deliveries could cause an address to be silently
		dropped.
	Include the initial user environment if sendmail is restarted via
		a HUP signal.  This will give room for the process title.
		Problem noted by Jon Lewis of Florida Digital Turnpike.
	Mail could be delivered without a body if the machine does not
		support flock locking and runs out of processes during
		delivery.  Fix from Chuck Lever of the University of Michigan.
	Drop recipient address from 251 and 551 SMTP responses per RFC 821.
		Problem noted by Kari E. Hurtta of the Finnish Meteorological
		Institute.
	Make sure non-rebuildable database maps are opened before the
		rebuildable maps (i.e., alias files) in case the database maps
		are needed for verifying the left hand side of the aliases.
		Problem noted by Lloyd Parkes of Victoria University.
	Make sure sender RFC822 source route addresses are alias expanded for
		bounce messages.  Problem noted by Juergen Georgi of
		RUS University of Stuttgart.
	Minor lint fixes.
	Return a temporary error instead of a permanent error if an LDAP map
		search returns an error.  This will allow sequenced maps which
		use other LDAP servers to be checked.  Fix from Booker Bense
		of Stanford University.
	When automatically converting from quoted printable to 8bit text do
		not pad bare linefeeds with a space.  Problem noted by Theo
		Nolte of the University of Technology Aachen, Germany.
	Portability:
		Non-standard C compilers may have had a problem compiling
			conf.c due to a standard C external declaration of
			setproctitle().  Problem noted by Ted Roberts of
			Electronic Data Systems.
		AUX: has a broken O_EXCL implementation.  Reported by Jim
			Jagielski of jaguNET Access Services.
		BSD/OS: didn't compile if HASSETUSERCONTEXT was defined.
		Digital UNIX: Digital UNIX (and possibly others) moves
			loader environment variables into the loader memory
			area.  If one of these environment variables (such as
			LD_LIBRARY_PATH) was the last environment variable,
			an invalid memory address would be used by the process
			title routine causing memory corruption.  Problem
			noted by Sam Hartman of Mesa Internet Systems.
		GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused
			chownsafe() to always return 0 even if the OS does
			not permit file giveaways.  Problem noted by
			Yasutaka Sumi of The University of Tokyo.
		IRIX6: Syslog buffer size set to 512 bytes.  Reported by
			Gerald Rinske of Siemens Business Services VAS.
		Linux: Pad process title with NULLs.  Problem noted by
			Jon Lewis of Florida Digital Turnpike.
		SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an
			incorrect value for the number of interfaces.
			Problem noted by Chris Loelke of JetStream Internet
			Services.
		SINIX: Update for Makefile and syslog buffer size from Gerald
			Rinske of Siemens Business Services VAS.
		Solaris: Make sure HASGETUSERSHELL setting for SunOS is not
			used on a Solaris machine.  Problem noted by
			Stephen Ma of Jtec Pty Limited.
		CONFIG: SINIX: Update from Gerald Rinske of Siemens Business
			Services VAS.
	MAKEMAP: Use a better heuristic for detecting GDBM.
	CONTRIB: expn.pl: Updated version from the author, David Muir Sharnoff.
	OP.ME: Document the F=i mailer flag.  Problem noted by Per Hedeland of
			Ericsson.

8.8.7/8.8.7	1997/08/03
	If using Berkeley DB on systems without O_EXLOCK (open a file with
		an exclusive lock already set -- i.e., almost all systems
		except 4.4-BSD derived systems), the initial attempt at
		rebuilding aliases file if the database didn't already
		exist would fail.  Patch from Raymund Will of LST Software
		GmbH.
	Bogus incoming SMTP commands would reset the SMTP conversation.
		Problem noted by Fredrik Jönsson of the Royal Institute
		of Technology, Stockholm.
	Since TCP Wrappers includes setenv(), unsetenv(), and putenv(),
		some environments could give "multiple definitions" for these
		routines during compilation.  If using TCP Wrappers, assume
		that these routines are included as though they were in the
		C library.  Patch from Robert La Ferla.
	When a NEWDB database map was rebuilt at the same time it was being
		used by a queue run, the maps could be left locked for the
		duration of the queue run, causing other processes to hang.
		Problem noted by Kendall Libby of Shore.NET.
	In some cases, NoRecipientAction=add-bcc was being ignored, so the
		mail was passed on without any recipient header.  This could
		cause problems downstream.  Problem noted by Xander Jansen
		of SURFnet ExpertiseCentrum.
	Give error when GDBM is used with sendmail.  GDBM's locking and
		linking of the .dir and .pag files interferes with sendmail's
		locking and security checks.  Problems noted by Fyodor
		Yarochkin of the Kyrgyz Republic FreeNet.
	Don't fsync qf files if SuperSafe option is not set.
	Avoid extra calls to gethostbyname for addresses for which a
		gethostbyaddr found no value.  Also, ignore any returns
		from gethostbyaddr that look like a dotted quad.
	If PTR lookup fails when looking up an SMTP peer, don't tag it as
		"may be forged", since at the network level we pretty much
		have to assume that the information is good.
	In some cases, errors during an SMTP session could leave files
		open or locked.
	Better handling of missing file descriptors (0, 1, 2) on startup.
	Better handling of non-set-user-ID binaries -- avoids certain obnoxious
		errors during testing.
	Errors in file locking of NEWDB maps had the incorrect file name
		printed in the error message.
	If the AllowBogusHELO option were set and an EHLO with a bad or
		missing parameter were issued, the EHLO behaved like a HELO.
	Load limiting never kicked in for incoming SMTP transactions if the
		DeliveryMode=background and any recipient was an alias or
		had a .forward file.  From Nik Conwell of Boston University.
	On some non-Posix systems, the decision of whether chown(2) permits
		file giveaway was undefined.  From Tetsu Ushijima of the
		Tokyo Institute of Technology.
	Fix race condition that could cause the body of a message to be
		lost (so only the header was delivered).  This only occurs
		on systems that do not use flock(2), and only when a queue
		runner runs during a critical section in another message
		delivery.  Based on a patch from Steve Schweinhart of
		Results Computing.
	If a qf file was found in a mail queue directory that had a problem
		(wrong ownership, bad format, etc.) and the file name was
		exactly MAXQFNAME bytes long, then instead of being tried
		once, it would be tried on every queue run.  Problem noted
		by Bryan Costales of Mercury Mail.
	If the system supports an st_gen field in the status structure,
		include it when reporting that a file has changed after open.
		This adds a new compile flag, HAS_ST_GEN (0/1 option).
		This out to be checked as well as reported, since it is
		theoretically possible for an attacker to remove a file after
		it is opened and replace it with another file that has the
		same i-number, but some filesystems (notably AFS) return
		garbage in this field, and hence always look like the file
		has changed.  As a practical matter this is not a security
		problem, since the files can be neither hard nor soft links,
		and on no filesystem (that I am aware of) is it possible to
		have two files on the same filesystem with the same i-number
		simultaneously.
	Delete the root Makefile from the distribution -- it is only for
		use internally, and does not work at customer sites.
	Fix botch that caused the second MAIL FROM: command in a single
		transaction to clear the entire transaction.  Problem
		noted by John Kennedy of Cal State University, Chico.
	Work properly on machines that have _PATH_VARTMP defined without
		a trailing slash.  (And a pox on vendors that decide to
		ignore the established conventions!)  Problem noted by
		Gregory Neil Shapiro of WPI.
	Internal changes to make it easier to add another protocol family
		(intended for IPv6).  Patches are from John Kennedy of
		CSU Chico.
	In certain cases, 7->8 bit MIME decoding of Base64 text could leave
		an extra space at the beginning of some lines.  Problem
		noted by Charles Karney of Princeton University; fix based
		on a patch from Christophe Wolfhugel.
	Portability:
		Allow _PATH_VENDOR_CF to be set in Makefile for consistency
			with the _Sendmail_ book, 2nd edition.  Note that
			the book is actually wrong: _PATH_SENDMAILCF should
			be used instead.
		AIX 3.x: Include <sys/select.h>.  Patch from Gene Rackow
			of Argonne National Laboratory.
		OpenBSD from from Paul DuBois of the University of Wisconsin.
		RISC/os 4.0 from Paul DuBois of the University of Wisconsin.
		SunOS: Include <memory.h> to fix warning from util.c.  From
			James Aldridge of EUnet Ltd.
		Solaris: Change STDIR (location of status file) to /etc/mail
			in Makefiles.
		Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from
			Makefiles.  Use NEWDB on Linux instead.
		NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl
			exists but behaves differently than other OSes.
			Add SIOCGIFNUM_IS_BROKEN compile flag to get
			around the problem.  Problem noted by Tom Moore of
			NCR Corp.
		HP-UX 9.x: fix compile warnings for old select API.  Problem
			noted by Tom Smith of Digital Equipment Corp.
		UnixWare 2.x: compile warnings on offsetof macro.  Problem
			noted by Tom Good of the Community Access Information
			Resource Network
		SCO 4.2: compile problems caused by a change in the type of
			the "length" parameters passed to accept, getpeername,
			getsockname, and getsockopt.  Adds new compile flags
			SOCKADDR_SIZE_T and SOCKOPT_SIZE_T.  Problem reported
			by Tom Good of St. Vincent's North Richmond Community
			Mental Health Center Residential Services.
		AIX 4: Use size_t for SOCKADDR_SIZE_T and SOCKOPT_SIZE_T.
			Suggested by Brett Hogden of Rochester Gas & Electric
			Corp.
		Linux: avoid compile problem for versions of <setjmp.h> that
			#define both setjmp and longjmp.  Problem pointed out
			by J.R. Oldroyd of TerraNet.
		CONFIG: SCO UnixWare 2.1: Support for OSTYPE(sco-uw-2.1)
			from Christopher Durham of SCO.
		CONFIG: NEXTSTEP: define confCW_FILE to
			/etc/sendmail/sendmail.cw to match the usual
			configuration.  Patch from Dennis Glatting of
			PlainTalk.
	CONFIG: MAILER(fax) called a program that hasn't existed for a long
		time.  Convert to use the HylaFAX 4.0 conventions.  Suggested
		by Harry Styron.
	CONFIG: Improve sample anti-spam rulesets in cf/cf/knecht.mc.  These
		are the rulesets in use on sendmail.org.
	MAKEMAP: give error on GDBM files.
	MAIL.LOCAL: Make error messages a bit more explicit, for example,
		telling more details on what actually changed when "file
		changed after open".
	CONTRIB: etrn.pl: Ignore comments in Fw files.  Support multiple Fw
		files.
	CONTRIB: passwd-to-alias.pl: Handle 8 bit characters and '-'.

8.8.6/8.8.6	1997/06/14
	    *************************************************************
	    * The extensive assistance of Gregory Neil Shapiro of WPI	*
	    * in preparing this release is gratefully appreciated.	*
	    * Sun Microsystems has also provided resources toward	*
	    * continued sendmail development.				*
	    *************************************************************
	SECURITY: A few systems allow an open with the O_EXCL|O_CREAT open
		mode bits set to create a file that is a symbolic link that
		points nowhere.  This makes it possible to create a root
		owned file in an arbitrary directory by inserting the symlink
		into a writable directory after the initial lstat(2) check
		determined that the file did not exist.  The only verified
		example of a system having these odd semantics for O_EXCL
		and symbolic links was HP-UX prior to version 9.07.  Most
		systems do not have the problem, since a exclusive create
		of a file disallows symbolic links.  Systems that have been
		verified to NOT have the problem include AIX 3.x, *BSD,
		DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris,
		and Ultrix.  This is a potential exposure on systems that
		have this bug and which do not have a MAILER-DAEMON alias
		pointing at a legitimate account, since this will cause old
		mail to be dropped in /var/tmp/dead.letter.
	SECURITY: Problems can occur on poorly managed systems, specifically,
		if maps or alias files are in world writable directories.
		If your system has alias maps in writable directories, it
		is potentially possible for an attacker to replace the .db
		(or .dir and .pag) files by symbolic links pointing at
		another database; this can be used either to expose
		information (e.g., by pointing an alias file at /etc/spwd.db
		and probing for accounts), or as a denial-of-service attack
		(by trashing the password database).  The fix disallows
		symbolic links entirely when rebuilding alias files or on
		maps that are in writable directories, and always warns on
		writable directories; 8.9 will probably consider writable
		directories to be fatal errors.  This does not represent an
		exposure on systems that have alias files in unwritable
		system directories.
	SECURITY: disallow .forward or :include: files that are links (hard
		or soft) if the parent directory (or any directory in the
		path) is writable by anyone other than the owner.  This is
		similar to the previous case for user files.  This change
		should not affect most systems, but is necessary to prevent
		an attacker who can write the directory from pointing such
		files at other files that are readable only by the owner.
	SECURITY: Tighten safechown rules: many systems will say that they
		have a safe (restricted to root) chown even on files that
		are mounted from another system that allows owners to give
		away files.  The new rules are very strict, trusting file
		ownership only in those few cases where the system has
		been verified to be at least as paranoid as necessary.
		However, it is possible to relax the rules to partially
		trust the ownership if the directory path is not world or
		group writable.  This might allow someone who has a legitimate
		:include: file (referenced directly from /etc/aliases) to
		become another non-root user if the :include: file is in a
		non-writable directory on an NFS-mounted filesystem where
		the local system says that giveaway is denied but it is
		actually permitted.  I believe this to be a very small set
		of cases.  If in doubt, do not point :include: aliases at
		NFS-mounted filesystems.
	SECURITY: When setting a numeric group id using the RunAsUser option
		(e.g., "O RunAsUser=10:20", the group id would not be set.
		Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha
		group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine.
		The user id was still set properly.  Problem noted by Uli
		Pralle of the Technical University of Berlin.
	Save the initial gid set for use when checking for if the
		PrivacyOptions=restrictmailq option is set.  Problem reported
		by Wolfgang Ley of DFN-CERT.
	Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a
		failure on one message won't affect future messages to the
		same host).
	IP source route printing had an "off by one" error that would
		affect any options that came after the route option.  Patch
		from Theo de Raadt.
	The "Message is too large" error didn't successfully bounce the error
		back to the sender.  Problem reported by Stephen More of
		PSI; patch from Gregory Neil Shapiro of WPI.
	Change SMTP status code 553 to map into Extended code 5.1.0 (instead
		of 5.1.3); it apparently gets used in multiple ways.
		Suggested by John Myers of Portola Communications.
	Fix possible extra null byte generated during collection if errors
		occur at the beginning of the stream.  Patch contributed by
		Andrey A. Chernov and Gregory Neil Shapiro.
	Code changes to avoid possible reentrant call of malloc/free within
		a signal handler.  Problem noted by John Beck of Sun
		Microsystems.
	Move map initialization to be earlier so that check_relay ruleset
		will have the latest version of the map data.  Problem noted
		by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro.
	If there are fatal errors during the collection phase (e.g., message
		too large) don't send the bogus message.
	Avoid "cannot open xfAAA00000" messages when sending to aliases that
		have errors and have owner- aliases.  Problem noted by Michael
		Barber of MTU; fix from Gregory Neil Shapiro of WPI.
	Avoid null pointer dereference on illegal Boundary= parameters in
		multipart/mixed Content-Type: header.  Problem noted by
		Richard Muirden of RMIT University.
	Always print error messages during newaliases (-bi) even if the
		ErrorMode is not set to "print".  Fix from Gregory Neil
		Shapiro.
	Test mode could core dump if you did a /map lookup in an optional map
		that could not be opened.  Based on a fix from John Beck of
		Sun Microsystems.
	If DNS is misconfigured so that the last MX record tried points to
		a host that does not have an A record, but other MX records
		pointed to something reasonable, don't bounce the message
		with a "host unknown" error.  Note that this should really
		be fixed in the zone file for the domain.  Problem noted by
		Joe Rhett of Navigist, Inc.
	If a map fails (e.g., DNS times out) on all recipient addresses, mark
		the message as having been tried; otherwise the next queue
		run will not realize that this is a second attempt and will
		retry immediately.  Problem noted by Bryan Costales of
		Mercury Mail.
	If the clock is set backwards, and a MinQueueAge is set, no jobs
		will be run until the later setting of the clock is reached.
		"Problem" (I use the term loosely) noted by Eric Hagberg of
		Morgan Stanley.
	If the load average rises above the cutoff threshold (above which
		sendmail will not process the queue at all) during a queue
		run, abort the queue run immediately.  Problem noted by
		Bryan Costales of Mercury Mail.
	The variable queue processing algorithm (based on the message size,
		number of recipients, message precedence, and job age) was
		non-functional -- either the entire queue was processed or
		none of the queue was processed.  The updated algorithm
		does no queue run if a single recipient zero size job will
		not be run.
	If there is a fatal ("panic") message that will cause sendmail to
		die immediately, never hold the error message for future
		printing.
	Force ErrorMode=print in -bt mode so that all errors are printed
		regardless of the setting of the ErrorMode option in the
		configuration file.  Patch from Gregory Neil Shapiro.
	New compile flag HASSTRERROR says that this OS has the strerror(3)
		routine available in one of the libraries.  Use it in conf.h.
	The -m (match only) flag now works on host class maps.
	If class hash or btree maps are rebuilt, sendmail will now detect
		this and reopen the map.  Previously, they could give
		erroneous results during a single message processing
		(but would recover when the next message was received).
	Don't delete zero length queue files when doing queue runs until the
		files are at least ten minutes old.  This avoids a potential
		race condition: the creator creates the qf file, getting back
		a file descriptor.  The queue runner locks it and deletes it
		because it is zero length.  The creator then writes the
		descriptor that is now for a disconnected file, and the
		job goes away.  Based on a suggestion by Bryan Costales.
	When determining the "validated" host name ($_ macro), do a forward
		(A) DNS lookup on the result of the PTR lookup and compare
		results.  If they differ or if the PTR lookup fails, tag the
		address as "may be forged".
	Log null connections (i.e., hosts that connect but do not do any
		substantive activity on the connection before disconnecting;
		"substantive" is defined to be MAIL, EXPN, VRFY, or ETRN.
	Always permit "writes" to /dev/null regardless of the link count.
		This is safe because /dev/null is special cased, and no open
		or write is ever actually attempted.  Patch from Villy Kruse
		of TwinCom.
	If a message cannot be sent because of a 552 (exceeded storage
		allocation) response to the MAIL FROM:<>, and a SIZE= parameter
		was given, don't return the body in the bounce, since there
		is a very good chance that the message will double-bounce.
	Fix possible line truncation if a quoted-printable had an =00 escape
		in the body.  Problem noted by Charles Karney of the Princeton
		Plasma Physics Laboratory.
	Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses.
		Problem noted by Kari Hurtta of the Finnish Meteorological
		Institute.
	The MaxDaemonChildren option wasn't applying to queue runs as
		documented.  Note that this increases the potential denial
		of service problems with this option: an attacker can
		connect many times, and thereby lock out queue runs as well
		as incoming connections.  If you use this option, you should
		run the "sendmail -bd" and "sendmail -q30m" jobs separately
		to avoid this attack.  Failure to limit noted by Matthew
		Dillon of BEST Internet Communications.
	Always give a message in newaliases if alias files cannot be
		opened instead of failing silently.  Suggested by Gregory
		Neil Shapiro.  This change makes the code match the O'Reilly
		book (2nd edition).
	Some older versions of the resolver could return with h_errno == -1
		if no name server could be reached, causing mail to bounce
		instead of queueing.  Treat this like TRY_AGAIN.  Fix from
		John Beck of SunSoft.
	If a :include: file is owned by a user that does not have an entry
		in the passwd file, sendmail could dereference a null pointer.
		Problem noted by Satish Mynam of Sun Microsystems.
	Take precautions to make sure that the SMTP protocol cannot get out
		of sync if (for example) an alias file cannot be opened.
	Fix a possible race condition that can cause a SIGALRM to come in
		immediately after a SIGHUP, causing the new sendmail to die.
	Avoid possible hang on SVr3 systems when doing child reaping.  Patch
		from Villy Kruse of TwinCom.
	Ignore improperly formatted SMTP reply codes.  Previously these were
		partially processed, which could cause confusing error
		returns.
	Fix possible bogus pointer dereference when doing ldapx map lookups
		on some architectures.
	Portability:
		A/UX: from Jim Jagielski of NASA/GSFC.
		glibc: SOCK_STREAM was changed from a #define to an enum,
			thus breaking #ifdef SOCK_STREAM.  Only option seems
			to be to assume SOCK_STREAM if __GNU_LIBRARY__ is
			defined.  Problem reported by A Sun of the University
			of Washington.
		Solaris: use SIOCGIFNUM to get the number of interfaces on
			the system rather than guessing at compile time.
			Patch contributed by John Beck of Sun Microsystems.
		Intel Paragon: from Wendy Lin of Purdue University.
		GNU Hurd: from Miles Bader of the GNU project.
		RISC/os 4.50 from Harlan Stenn of PFCS Corporation.
		ISC Unix: wait never returns if SIGCLD signals are blocked.
			Unfortunately releasing them opens a race condition,
			but there appears to be no fix for this.  Patch from
			Gregory Neil Shapiro.
		BIND 8.1 for IPv6 compatibility from John Kennedy.
		Solaris: a bug in strcasecmp caused characters with the
			high order bit set to apparently randomly match
			letters -- for example, $| (0233) matches "i" and "I".
			Problem noted by John Gregson of the University of
			Cambridge.
		IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x.  From
			Kari Hurtta.
		IRIX 6.x: Create Makefiles for systems that claim to be
			IRIX64 but are 6.2 or higher (so use the regular
			IRIX Makefile).
		IRIX 6.x: Fix load average computation on 64 bit kernels.
			Problem noted by Eric Hagberg of Morgan Stanley.
	CONFIG: Some canonification was still done for UUCP-like addresses
		even if FEATURE(nocanonify) was set.  Problem pointed out by
		Brian Candler.
	CONFIG: In some cases UUCP mailers wouldn't properly recognize all
		local names as local.  Problem noted by Jeff Polk of BSDI;
		fix provided by Gregory Neil Shapiro.
	CONFIG: The "local:user" syntax entries in mailertables and other
		"mailer:user" syntax locations returned an incorrect value
		for the $h macro.  Problem noted by Gregory Neil Shapiro.
	CONFIG: Retain "+detail" information when forwarding mail to a
		MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY.  Patch from Philip
		Guenther of Gustavus Adolphus College.
	CONFIG: Make sure user+detail works for FEATURE(virtusertable);
		rules are the same as for aliasing.  Based on a patch from
		Gregory Neil Shapiro.
	CONFIG: Break up parsing rules into several pieces; this should
		have no functional change in this release, but makes it
		possible to have better anti-spam rulesets in the future.
	CONFIG: Disallow double dots in host names to avoid having the
		HostStatusDirectory store status under the wrong name.
		In some cases this can be used as a denial-of-service attack.
		Problem noted by Ron Jarrell of Virginia Tech, patch from
		Gregory Neil Shapiro.
	CONFIG: Don't use F=m (multiple recipients per invocation) for
		MAILER(procmail), but do pass F=Pn9 (include Return-Path:,
		don't include From_, and convert to 8-bit).  Suggestions
		from Kimmo Suominen and Roderick Schertler.
	CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were
		being masqueraded as though FEATURE(masquerade_entire_domain)
		was specified, even when it wasn't.
	MAIL.LOCAL: Solaris 2.6 has snprintf.  From John Beck of SunSoft.
	MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't
		"slip in" a symbolic link between the lstat(2) call and the
		exclusive open.  This is only a problem on System V derived
		systems that allow an exclusive create on files that are
		symbolic links pointing nowhere.
	MAIL.LOCAL: If the final mailbox close() failed, the user id was
		not reset back to root, which on some systems would cause
		later mailboxes to fail.  Also, any partial message would
		not be truncated, which could result in repeated deliveries.
		Problem noted by Bruce Evans via Peter Wemm (FreeBSD
		developers).
	MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0.  A similar
		change to the sendmail map code was made in 8.8.3.  Problem
		noted by Gregory Neil Shapiro.
	MAKEMAP: Give warnings on file problems such as map files that are
		symbolic links; although makemap is not set-user-ID root, it is
		often run as root and hence has the potential for the same
		sorts of problems as alias rebuilds.
	MAKEMAP: Change compilation so that it will link properly on
		NEXTSTEP.
	CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf.
		Accept an optional list of arguments following the server
		name for the ETRN arguments to use (instead of $=w).  Other
		miscellaneous bug fixes.  From Christian von Roques via
		John Beck of Sun Microsystems.
	CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta.  This
		Perl script converts GECOS information in the /etc/passwd
		file into aliases, allowing for faster access to full name
		lookups; it is also clever about adding aliases (to root)
		for system accounts.

8.8.5/8.8.5	1997/01/21
	SECURITY: Clear out group list during startup.  Without this, sendmail
		will continue to run with the group permissions of the caller,
		even if RunAsUser is specified.
	SECURITY: Make purgestat (-bH) be root-only.  This is not in response
		to any known attack, but it's best to be conservative.
		Suggested by Peter Wemm of DIALix.
	SECURITY: Fix buffer overrun problem in MIME code that has possible
		security implications.  Patch from Alex Garthwaite of the
		University of Pennsylvania.
	Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'")
		would truncate the address after "Full".  Although the -f
		syntax is incorrect (since it is in the envelope, it
		shouldn't have comments and full names), the failure mode
		was unnecessarily awful.
	Fix a possible null pointer dereference when converting 8-bit data
		to a 7-bit format.  Problem noted by Jim Hutchins of
		Sandia National Labs and David James of British Telecom.
	Clear out stale state that affected F=9 on SMTP mailers in queue
		runs.  Although this really shouldn't be used (F=9 is for
		final delivery only, and using it on an SMTP mailer makes
		it possible for a message to be converted from 8->7->8->7
		bits several times), it shouldn't have failed with a syserr.
		Problem noted by Eric Hagberg of Morgan Stanley.
	_Really_ fix the multiple :maildrop code in the user database
		module.  Patch from Roy Mongiovi of Georgia Tech.
	Let F lines in the configuration file actually read root-only
		files if the configuration file is safe.  Based on a
		patch from Keith Reynolds of SCO.
	ETRN followed by QUIT would hold the connection open until the queue
		run completed.  Problem noted by Truck Lewis of TDK
		Semiconductor Corp.
	It turns out that despite the documentation, the TCP wrappers library
		does _not_ log rejected connections.  Do the logging ourselves.
		Problem noted by Fletcher Mattox of the University of Texas
		at Austin.
	If sendmail finds a qf file in its queue directory that is an unknown
		version (e.g., when backing out to an old version), the
		error is reported on every queue run.  Change it to only
		give the error once (and rename the qf => Qf).  Patch from
		William A. Gianopoulos of Raytheon Company.
	Start a new session when doing background delivery; currently it
		ignored signals but didn't start a new signal, that caused
		some problems if a background process tried to send mail
		under certain circumstances.  Problem noted by Eric Hagberg
		of Morgan Stanley; fix from Kari Hurtta.
	Simplify test for skipping a queue run to just check if the current
		load average is >= the queueing load average.  Previously
		the check factored in some other parameters that caused it
		to essentially never skip the queue run.  Patch from Bryan
		Costales.
	If the SMTP server is running in "nullserver" mode (that is, it is
		rejecting all commands), start sleeping after MAXBADCOMMAND
		(25) commands; this helps prevent a bad guy from putting
		you into a tight loop as a denial-of-service attack.  Based
		on an e-mail conversation with Brad Knowles of AOL.
	Slow down when too many "light weight" commands have been issued;
		this helps prevent a class of denial-of-service attacks.
		The current values and defaults are:
		    MAXNOOPCOMMANDS	20	NOOP, VERB, ONEX, XUSR
		    MAXHELOCOMMANDS	3	HELO, EHLO
		    MAXVRFYCOMMANDS	6	VRFY, EXPN
		    MAXETRNCOMMANDS	8	ETRN
		These will probably be configurable in a future release.
	On systems that have uid_t typedefed to be an unsigned short, programs
		that had the F=S flag and no U= equate would be invoked with
		the real uid set to 65535 rather than being left unchanged.
	In some cases, NOTIFY=NEVER was not being honored.  Problem noted
		by Steve Hubert of the University of Washington, Seattle.
	Mail that was Quoted-Printable encoded and had a soft line break on
		the last line (i.e., an incomplete continuation) had the last
		line dropped.  Since this appears to be illegal it isn't
		clear what to do with it, but flushing the last line seems
		to be a better "fail soft" approach.  Based on a patch from
		Eric Hagberg.
	If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a
		bogus HELO command still causes the "Polite people say HELO
		first" error message.  Problem pointed out by Chris Thomas
		of UCLA; patch from John Beck of SunSoft.
	Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set
		in PrivacyOptions.  The -q shouldn't turn this command off.
		Problem noted by Murray Kucherawy of Pacific Bell Internet;
		based on a patch from Gregory Neil Shapiro of WPI.
	Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation)
		in a DATA transaction to be sticky; these can occur because
		a message is too large, and smaller messages should still go
		through.  Problem noted by Matt Dillon of Best Internet
		Communications.
	In some cases bounces were saved in /var/tmp/dead.letter even if they
		had been successfully delivered to the envelope sender.
		Problem noted Eric Hagberg of Morgan Stanley; solution from
		Gregory Neil Shapiro of WPI.
	Give better diagnostics on long alias lines.  Based on code contributed
		by Patrick Gosling of the University of Cambridge.
	Increase the number of virtual interfaces that will be probed for
		alternate names.  Problem noted by Amy Rich of Shore.Net.
	PORTABILITY:

	CONFIG: It seems that I hadn't gotten the Received: line syntax
		_just_right_ yet.  Tweak it again.  I'll omit the names
		of the "contributors" (quantity two) in this one case.
		As of now, NO MORE DISCUSSION about the syntax of the
		Received: line.
	CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E),
		it never inserts that class into the output file.  Fix it
		so it will honor EXPOSED_USER but will _not_ include root
		automatically in this class.  Problem noted by Ronan KERYELL
		of Centre de Recherche en Informatique de l'École Nationale
		Supérieure des Mines de Paris (CRI-ENSMP).
	CONFIG: Clean up handling of "local:" syntax in relay specifications
		such as LUSER_RELAY.  This change permits the following
		syntaxes:  ``local:'' will send to the same user on the
		local machine (e.g., in a mailertable entry for "host",
		``local:'' will cause an address addressed to user@host to
		go to user on the local machone).  ``local:user'' will send
		to the named user on the local machine.  ``local:user@host''
		is equivalent to ``local:user'' (the host is ignored).  In
		all cases, the original user@host is passed in $@ (i.e., the
		detail information).  Inspired by a report from Michael Fuhr.
	CONFIG: Strip quotes from the first word of an "error:" host
		indication.  This lets you set (for example) the LUSER_RELAY
		to be ``error:\"5.1.1\" Your Message Here''.  Note the use
		of the \" so that the resulting string is properly quoted.
		Problem noted by Gregory Neil Shapiro of WPI.
	OP.ME: documentation was inconsistent about whether sendmail did a
		NOOP or a RSET to probe the connection (it does a RSET).
		Inconsistency noted by Deeran Peethamparam.
	OP.ME: insert additional blank pages so it will print properly on
		a duplex printer.  From Matthew Black of Cal State University,
		Long Beach.

8.8.4/8.8.4	1996/12/02
	SECURITY: under some circumstances, an attacker could get additional
		permissions by hard linking to files that were group
		writable by the attacker.  The solution is to disallow any
		files that have hard links -- this will affect .forward,
		:include:, and output files.  Problem noted by Terry
		Kyriacopoulos of Interlog Internet Services.  As a
		workaround, set UnsafeGroupWrites -- always a good idea.
	SECURITY: the TryNullMXList (w) option should not be safe -- if it
		is, it is possible to do a denial-of-service attack on
		MX hosts that rely on the use of the null MX list.  There
		is no danger if you have this option turned off (the default).
		Problem noted by Dan Bernstein.  Also, make the DontInitGroups
		unsafe.  I know of no specific attack against this, although
		a denial-of-service attack is probably possible, but in theory
		you should not be able to safely tweak anything that affects
		the permissions that are used when mail is delivered.
	Purgestat could go into an infinite loop if one of the host status
		directories somehow became empty.  Problem noted by Roy
		Mongiovi of Georgia Tech.
	Processes got "lost" when counting children due to a race condition.
		This caused "proc_list_probe: lost pid" messages to be logged.
		Problem noted by several people.
	On systems with System V SIGCLD child signal semantics (notably AIX
		and HP-UX), mail transactions would print the message "451
		SMTP-MAIL: lost child: No child processes".  Problem noted
		by several people.
	Miscellaneous compiler warnings on picky compilers (or when setting
		gcc to high warning levels).  From Tom Moore of NCR Corp.
	SMTP protocol errors, and most errors on MAIL FROM: lines should
		not be persistent between runs, since they are based on the
		message rather than the host.  Problem noted by Matt Dillon
		of Best Internet Communications.
	The F=7 flag was ignored on SMTP mailers.  Problem noted by Tom Moore
		of NCR (a.k.a., AT&T Global Information Solutions).
	Avoid the possibility of having a child daemon run to completion
		(including closing the SMTP socket) before the parent has
		had a chance to close the socket; this can cause the parent
		to hang for a long time waiting for the socket to drain.
		Patch from Don Lewis of TDK Semiconductor.
	If the fork() failed in a queue run, the queue runners would not be
		rescheduled (so queue runs would stop).  Patch from Don Lewis.
	Some error conditions in ETRN could cause output without an SMTP
		status code.  Problem noted by Don Lewis.
	Multiple :maildrop addresses in the user database didn't work properly.
		Patch from Roy Mongiovi of Georgia Tech.
	Add ".db" automatically onto any user database spec that does not
		already have it; this is for consistency with makemap, the
		K line, and the documentation.  Inconsistency pointed out
		by Roy Mongiovi.
	Allow sendmail to be properly called in nohup mode.  Patch from
		Kyle Jones of UUNET.
	Change ETRN to ignore but still update host status files; previously
		it would ignore them and not save the updated status, which
		caused stale information to be maintained.  Based on a patch
		from Christopher Davis of Kapor Enterprises Inc.  Also, have
		ETRN ignore the MinQueueAge option.
	Patch long term host status to recover more gracefully from an empty
		host status file condition.  Patch from NAKAMURA Motonori
		of Kyoto University.
	Several patches to signal handling code to fix potential race
		conditions from Don Lewis.
	Make it possible to compile with -DDAEMON=0 (previously it had some
		compile errors).  This turns DAEMON, QUEUE, and SMTP into
		0/1 compilation flags.  Note that DAEMON is an obsolete
		compile flag; use NETINET instead.  Solution based on a
		patch from Bryan Costales.
	PORTABILITY FIXES:
		AIX4: getpwnam() and getpwuid() do a sequential scan of the
			/etc/security/passwd file when called as root.  This
			is very slow on some systems.  To speed it up, use the
			(undocumented) _getpw{nam,uid}_shadow() routines.
			Patch from Chris Thomas of UCLA/OAC Systems Group.
		SCO 5.x: include -lprot in the Makefile.  Patch from Bill
			Glicker of Burrelle's Information Service.
		NEWS-OS 4.x: need a definition for MODE_T to compile.  Patch

8.8.3/8.8.3	1996/11/17
	SECURITY: it was possible to get a root shell by lying to sendmail
		about argv[0] and then sending it a signal.  Problem noted
		by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the
		best-of-security list.
	Log sendmail binary version number in "Warning: .cf version level
		(%d) exceeds program functionality (%d) message" -- this
		should make it clearer to people that they are running
		the wrong binary.
	Fix a problem that occurs when you open an SMTP connection and then
		do one or more ETRN commands followed by a MAIL command; at
		the end of the DATA phase sendmail would incorrectly report
		"451 SMTP-MAIL: lost child: No child processes".  Problem
		noted by Eric Bishop of Virginia Tech.
	When doing text-based host canonification (typically /etc/hosts
		lookup), a null host name would match any /etc/hosts entry
		with space at the end of the line.  Problem noted by Steve
		Hubert of the University of Washington, Seattle.
	7 to 8 bit BASE64 MIME conversions could duplicate bits of text.
		Problem reported by Tom Smith of Digital Equipment Corp.
	Increase the size of the DNS answer buffer -- the standard UDP packet
		size PACKETSZ (512) is not sufficient for some nameserver
		answers containing very many resource records.  The resolver
		may also switch to TCP and retry if it detects UDP packet
		overflow.  Also, allow for the fact that the resolver
		routines res_query and res_search return the size of the
		*un*truncated answer in case the supplied answer buffer it
		not big enough to accommodate the entire answer.  Patch from
		Eric Wassenaar.
	Improvements to MaxDaemonChildren code.  If you think you have too
		many children, probe the ones you have to verify that they
		are still around.  Suggested by Jared Mauch of CICnet, Inc.
		Also, do this probe before growing the vector of children
		pids; this previously caused the vector to grow indefinitely
		due to a race condition.  Problem reported by Kyle Jones of
		UUNET.
	On some architectures, <db.h> (from the Berkeley DB library) defines
		O_EXLOCK to zero; this fools the map compilation code into
		thinking that it can avoid race conditions by locking on open.
		Change it to check for O_EXLOCK non-zero.  Problem noted by
		Leif Erlingsson of Data Lege.
	Always call res_init() on startup (if compiled in, of course) to
		allow the sendmail.cf file to tweak resolver flags; without
		it, flag tweaks in ResolverOptions are ignored.  Patch from
		Andrew Sun of Merrill Lynch.
	Improvements to host status printing code.  Suggested by Steve Hubert
		of the University of Washington, Seattle.
	Change MinQueueAge option processing to do the check for the job age
		when reading the queue file, rather than at the end; this
		avoids parsing the addresses, which can do DNS lookups.
		Problem noted by John Beck of InReference, Inc.
	When MIME was being 7->8 bit decoded, "From " lines weren't being
		properly escaped.  Problem noted by Peter Nilsson of the
		University of Linkoping.
	In some cases, sendmail would retain root permissions during queue
		runs even if RunAsUser was set.  Problem noted by Mark
		Thomas of Mark G. Thomas Consulting.
	If the F=l flag was set on an SMTP mailer to indicate that it is
		actually local delivery, and NOTIFY=SUCCESS is specified in
		the envelope, and the receiving SMTP server speaks DSN, then
		the DSN would be both generated locally and propagated to the
		other end.
	The U= mailer field didn't correctly extract the group id if the
		user id was numeric.  Problem noted by Kenneth Herron of
		MCI Telecommunications Communications.
	If a message exceeded the fixed maximum size on input, the body of
		the message was included in the bounce.  Note that this did
		not occur if it exceeded the maximum _output_ size.  Problem
		reported by Kyle Jones of UUNET.
	PORTABILITY FIXES:
		AIX4: 4.1 doesn't have a working setreuid(2); change the
			AIX4 defines to use seteuid(2) instead, which
			works on 4.1 as well as 4.2.  Problem noted by
			Håkan Lindholm of interAF, Sweden.
		AIX4: use tzname[] vector to determine time zone name.
			Patch from NAKAMURA Motonori of Kyoto University.
		MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support.
			Contributed by Paul DuBois <dubois@primate.wisc.edu>.
		Solaris: kstat(3k) support for retrieving the load average.
			This adds the LA_KSTAT definition for LA_TYPE.
			The outline of the implementation was contributed
			by Michael Tokarev of Telecom Service, JSC, Moscow.
		HP-UX 10.0 gripes about the (perfectly legal!) forward
			declaration of struct rusage at the top of conf.h;
			change it to only be included if you are using gcc,
			which is apparently the only compiler that requires
			it in the first place.  Problem noted by Jeff
			Earickson of Colby College.
		IRIX: don't default to using gcc.  IRIX is a civilized
			operating system that comes with a decent compiler
			by default.  Problem noted by Barry Bouwsma and
			Kari Hurtta.
	CONFIG: specify F=9 as default in FEATURE(local_procmail) for
		consistency with other local mailers.  Inconsistency
		pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>.
	CONFIG: if the "limited best mx" feature is used (to reduce DNS
		overhead) as part of the bestmx_is_local feature, the
		domain part was dropped from the name.  Patch from Steve
		Hubert of the University of Washington, Seattle.
	CONFIG: catch addresses of the form "user@.dom.ain"; these could
		end up being translated to the null host name, which would
		return any entry in /etc/hosts that had a space at the end
		of the line.  Problem noted by Steve Hubert of the
		University of Washington, Seattle.
	CONFIG: add OSTYPE(aix4).  From Michael Sofka of Rensselaer
		Polytechnic Institute.
	MAKEMAP: tweak hash and btree parameters for better performance.
		Patch from Matt Dillon of Best Internet Communications.

8.8.2/8.8.2	1996/10/18
	SECURITY: fix a botch in the 7-bit MIME patch; the previous patch
		changed the code but didn't fix the problem.
	PORTABILITY FIXES:
		Solaris: Don't use the system getusershell(3); it can
			apparently corrupt the heap in some circumstances.
			Problem found by Ken Pizzini of Spry, Inc.
	OP.ME: document several mailer flags that were accidentally omitted
		from this document.  These flags were F=d, F=j, F=R, and F=9.
	CONFIG: no changes.

8.8.1/8.8.1	1996/10/17
	SECURITY: unset all environment variables that the resolver will
		examine during queue runs and daemon mode.  Problem noted
		by Dan Bernstein of the University of Illinois at Chicago.
	SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain
		message could overflow a buffer if it was converted back
		to 8 bits.  This caused core dumps and has the potential
		for a remote attack.  Problem first noted by Gregory Shapiro
		of WPI.
	Avoid duplicate deliveries of error messages on systems that don't
		have flock(2) support.  Patch from Motonori Nakamura of
		Kyoto University.
	Ignore null FallBackMX (V) options.  If this option is null (as
		opposed to undefined) it can cause "null signature" syserrs
		on illegal host names.
	If a Base64 encoded text/plain message has no trailing newline in
		the encoded text, conversion back to 8 bits will drop the
		final line.  Problem noted by Pierre David.
	If running with a RunAsUser, sendmail would give bogus "cannot
		setuid" (or seteuid, or setreuid) messages on some systems.
		Problem pointed out by Jordan Mendelson of Web Services, Inc.
	Always print error messages in -bv mode -- previously, -bv would
		be absolutely silent on errors if the error mode was sent
		to (say) mail-back.  Problem noted by Kyle Jones of UUNET.
	If -qI/R/S is set (or the ETRN command is used), ignore all long
		term host status.  This is necessary because it is common
		to do this when you know a host has just come back up.
	Disallow duplicate HELO/EHLO commands as required by RFC 1651 section
		4.2.  Excessive permissiveness noted by Lee Flight of the
		University of Leicester.
	If a service (such as NIS) is specified as the last entry in the
		service switch, but that service is not compiled in, sendmail
		would return a temporary failure when an entry was not found
		in the map.  This caused the message to be queued instead of
		bouncing immediately.  Problem noted by Harry Edmon of the
		University of Washington.
	PORTABILITY FIXES:
		Solaris 2.3 had compilation problems in conf.c.  Several
			people pointed this out.
		NetBSD from Charles Hannum of MIT.
		AIX4 improvements based on info from Steve Bauer of South
			Dakota School of Mines & Technology.
	CONFIG: ``error:code message'' syntax was broken in virtusertable.
		Patch from Gil Kloepfer Jr.
	CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set
		using MASQUERADE_DOMAIN) were not masqueraded unless they
		were also in $=w.  Problem noted by Zoltan Basti of
		Softec.
	MAIL.LOCAL: patches to compile and link cleanly on AIX.  Based
		on a patch from Eric Hagberg of Morgan Stanley.
	MAIL.LOCAL: patches to compile on NEXTSTEP.  From Patrick Nolan
		of Stanford via Robert La Ferla.

8.8.0/8.8.0	1996/09/26
	Under some circumstances, Bcc: headers would not be properly
		deleted.  Pointed out by Jonathan Kamens of OpenVision.
	Log a warning if the sendmail daemon is invoked without a full
		pathname, which prevents "kill -1" from working.  I was
		urged to put this in by Andrey A. Chernov of DEMOS (Russia).
	Fix small buffer overflow.  Since the data in this buffer was not
		read externally, there was no security problem (and in fact
		probably wouldn't really overflow on most compilers).  Pointed
		out by KIZU takashi of Osaka University.
	Fix problem causing domain literals such as [1.2.3.4] to be ignored
		if a FallbackMXHost was specified in the configuration file
		-- all mail would be sent to the fallback even if the original
		host was accessible.  Pointed out by Munenari Hirayama of
		NSC (Japan).
	A message that didn't terminate with a newline would (sometimes) not
		have the trailing "." added properly in the SMTP dialogue,
		causing SMTP to hang.  Patch from Per Hedeland of Ericsson.
	The DaemonPortOptions suboption to bind to a particular address was
		incorrect and nonfunctional due to a misunderstanding of the
		semantics of binding on a passive socket.  Patch from
		NIIBE Yutaka of Mitsubishi Research Institute.
	Increase the number of MX hosts for a single name to 100 to better
		handle the truly huge service providers such as AOL, which
		has 13 at the moment (and climbing).  In order to avoid
		trashing memory, the buffer for all names has only been
		slightly increased in size, to 12.8K from 10.2K -- this means
		that if a single name had 100 MX records, the average size
		of those records could not exceed 128 bytes.  Requested by
		Brad Knowles of America On Line.
	Restore use of IDENT returns where the OSTYPE field equals "OTHER".
		Urged by Dan Bernstein of U.C. Berkeley.
	Print q_statdate and q_specificity in address structure debugging
		printout.
	Expand MCI structure flag bits for debugging output.
	Support IPv6-style domain literals, which can have colons between
		square braces.
	Log open file descriptors for the "cannot dup" messages in deliver();
		this is an attempt to track down a bug that one person seems
		to be having (it may be a Solaris bug!).
	DSN NOTIFY parameters were not properly propagated across queue runs;
		this caused the NOTIFY info to sometimes be lost.  Problem
		pointed out by Claus Assmann of the
		Christian-Albrechts-University of Kiel.
	The statistics gathered in the sendmail.st file were too high; in
		some cases failures (e.g., user unknown or temporary failure)
		would count as a delivery as far as the statistics were
		concerned.  Problem noted by Tom Moore of AT&T GIS.
	Systems that don't have flock() would not send split envelopes in
		the initial run.  Problem pointed out by Leonard Zubkoff of
		Dandelion Digital.
	Move buffer overflow checking -- these primarily involve distrusting
		results that may come from NIS and DNS.
	4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't
		include <paths.h> and hence had the wrong pathnames for a few
		things like /var/tmp.  Reported by Matthew Green.
	Conditions were reversed for the Priority: header, resulting in all
		values being interpreted as non-urgent except for non-urgent,
		which was interpreted as normal.  Patch from Bryan Costales.
	The -o (optional) flag was being ignored on hash and btree maps
		since 8.7.2.  Fix from Bryan Costales.
	Content-Types listed in class "q" will always be encoded as
		Quoted-Printable (or more accurately, will never be encoded
		as base64).  The class can have primary types (e.g., "text")
		or full types (e.g., "text/plain").  Based on a suggestion by
		Marius Olafsson of the University of Iceland.
	Define ${envid} to be the original envelope id (from the ESMTP DSN
		dialogue) so it can be passed to programs in mailers.
	Define ${bodytype} to be the body type (from the -B flag or the
		BODY= ESMTP parameter) so it can be passed to programs in
		mailers.
	Cause the VRFY command to return 252 instead of 250 unless the F=q
		flag is set in the mailer descriptor.  Suggested by John
		Myers of CMU.
	Implement ESMTP ETRN command to flush the queue for a specific host.
		The command takes a host name; data for that host is
		immediately (and asynchronously) flushed.  Because this shares
		the -qR implementation, other hosts may be attempted, but
		there should be no security implications.  Implementation
		from John Beck of InReference, Inc.  See RFC 1985 for details.
	Add three new command line flags to pass in DSN parameters: -V envid
		(equivalent to ENVID=envid on the MAIL command), -R ret
		(equivalent to RET=ret on the MAIL command), and -Nnotify
		(equivalent to NOTIFY=notify on the RCPT command).  Note
		that the -N flag applies to all recipients; there is no way
		to specify per-address notifications on the command line,
		nor is there an equivalent for the ORCPT= per-address
		parameter.
	Restore LogLevel option to be safe (it can only be increased);
		apparently I went into paranoid mode between 8.6 and 8.7
		and made it unsafe.  Pointed out by Dabe Murphy of the
		University of Maryland.
	New logging on log level 15:  all SMTP traffic.  Patches from
		Andrew Gross of San Diego Supercomputer Center.
	NetInfo property value searching code wasn't stopping when it found
		a match.  This was causing the wrong values to be found (and
		had a memory leak).  Found by Bastian Schleuter of TU-Berlin.
	Add new F=0 (zero) mailer flag to turn off MX lookups.  It was pointed
		out by Bill Wisner of Electronics for Imaging that you can't
		use the bracket address form for the MAIL_HUB macro, since
		that causes the brackets to remain in the envelope recipient
		address used for delivery.  The simple fix (stripping off the
		brackets in the config file) breaks the use of IP literal
		addresses.  This flag will solve that problem.
	Add MustQuoteChars option.  This is a list of characters that must
		be quoted if they are found in the phrase part of an address
		(that is, the full name part).  The characters @,;:\()[] are
		always in this list and cannot be removed.  The default is
		this list plus . and ' to match RFC 822.
	Add AllowBogusHELO option; if set, sendmail will allow HELO commands
		that do not include a host name for back compatibility with
		some stupid SMTP clients.  Setting this violates RFC 1123
		section 5.2.5.
	Add MaxDaemonChildren option; if this is set, sendmail will start
		rejecting connections if it has more than this many
		outstanding children accepting mail.  Note that you may
		see more processes than this because of outgoing mail; this
		is for incoming connections only.
	Add ConnectionRateThrottle option.  If set to a positive value, the
		number of incoming SMTP connections that will be permitted
		in a single second is limited to this number.  Connections are
		not refused during this time, just deferred.  The intent is to
		flatten out demand so that load average limiting can kick in.
		It is less radical than MaxDaemonChildren, which will stop
		accepting connections even if all the connections are idle
		(e.g., due to connection caching).
	Add Timeout.hoststatus option.  This interval (defaulting to 30m)
		specifies how long cached information about the state of a
		host will be kept before they are considered stale and the
		host is retried.  If you are using persistent host status
		(i.e., the HostStatusDirectory option is set) this will apply
		between runs; otherwise, it applies only within a single queue
		run and hence is useful only for hosts that have large queues
		that take a very long time to run.
	Add SingleLineFromHeader option.  If set, From: headers are coerced
		into being a single line even if they had newlines in them
		when read.  This is to get around a botch in Lotus Notes.
	Text class maps were totally broken -- if you ever retrieved the last
		item in a table it would be truncated.  Problem noted by
		Gregory Neil Shapiro of WPI.
	Extend the lines printed by the mailq command (== the -bp flag) when
		-v is given to 120 characters; this allows more information
		to be displayed.  Suggested by Gregory Neil Shapiro of WPI.
	Allow macro definitions (`D' lines) with unquoted commas; previously
		this was treated as end-of-input.  Problem noted by Bryan
		Costales.
	The RET= envelope parameter (used for DSNs) wasn't properly written
		to the queue file.  Fix from John Hughes of Atlantic
		Technologies, Inc.
	Close /var/tmp/dead.letter after a successful write -- otherwise
		if this happens in a queue run it can cause nasty delays.
		Problem noted by Mark Horton of AT&T.
	If userdb entries pointed to userdb entries, and there were multiple
		values for a given key, the database cursor would get
		trashed by the recursive call.  Problem noted by Roy Mongiovi
		of Georgia Tech.  Fixed by reading all the values and creating
		a comma-separated list; thus, the -v output will be somewhat
		different for this case.
	Fix buffer allocation problem with Hesiod-based userdb maps when
		HES_GETMAILHOST is defined.  Based on a patch by Betty Lee
		of Stanford University.
	When envelopes were split due to aliases with owner- aliases, and
		there was some error on one of the lists, more than one of
		the owners would get the message.  Problem pointed out by
		Roy Mongiovi of Georgia Tech.
	Detect excessive recursion in macro expansions, e.g., $X defined
		in terms of $Y which is defined in terms of $X.  Problem
		noted by Bryan Costales; patch from Eric Wassenaar.
	When using F=U to get "ugly UUCP" From_ lines, a buffer could in
		some cases get trashed causing bogus From_ lines.  Fix from
		Kyle Jones of UUNET.
	When doing load average initialization, if the nlist call for avenrun
		failed, the second and subsequent lookups wouldn't notice
		that fact causing bogus load averages to be returned.  Noted
		by Casper Dik of Sun Holland.
	Fix problem with incompatibility with some versions of inet_aton that
		have changed the return value to unsigned, so a check for an
		error return of -1 doesn't work.  Use INADDR_NONE instead.
		This could cause mail to addresses such as [foo.com] to bounce
		or get dropped.  Problem noted by Christophe Wolfhugel of the
		Pasteur Institute.
	DSNs were inconsistent if a failure occurred during the DATA phase
		rather than the RCPT phase: the Action: would be correct, but
		the detailed status information would be wrong.  Problem noted
		by Bob Snyder of General Electric Company.
	Add -U command line flag and the XUSR ESMTP extension, both indicating
		that this is the initial MUA->MTA submission.  The flag current
		does nothing, but in future releases (when MUAs start using
		these flags) it will probably turn on things like DNS
		canonification.
	Default end-of-line string (E= specification on mailer [M] lines)
		to \r\n on SMTP mailers.  Default remains \n on non-SMTP
		mailers.
	Change the internal definition for the *file* and *include* mailers
		to have $u in the argument vectors so that they aren't
		misinterpreted as SMTP mailers and thus use \r\n line
		termination.  This will affect anyone who has redefined
		either of these in their configuration file.
	Don't assume that IDENT servers close the connection after a query;
		responses can be newline terminated.  From Terry Kennedy of
		St. Peter's College.
	Avoid core dumps on erroneous configuration files that have
		$#mailer with nothing following.  From Bryan Costales.
	Avoid null pointer dereference with high debug values in unlockqueue.
		Fix from Randy Martin of Clemson University.
	Fix possible buffer overrun when expanding very large macros.  Fix
		from Kyle Jones of UUNET.
	After 25 EXPN or VRFY commands, start pausing for a second before
		processing each one.  This avoids a certain form of denial
		of service attack.  Potential attack pointed out by Bryan
		Costales.
	Allow new named (not numbered!) config file rules to do validity
		checking on SMTP arguments: check_mail for MAIL commands and
		check_rcpt for RCPT commands.  These rulesets can do anything
		they want; their result is ignored unless they resolve to the
		$#error mailer, in which case the indicated message is printed
		and the command is rejected.  Similarly, the check_compat
		ruleset is called before delivery with "from_addr $| to_addr"
		(the $| is a meta-symbol used to separate the two addresses);
		it can give a "this sender can't send to this recipient"
		notification.  Note that this patch allows $| to stand alone
		in rulesets.
	Define new macros ${client_name}, ${client_addr}, and ${client_port}
		that have the name, IP address, and port number (respectively)
		of the SMTP client (that is, the entity at the other end of
		the connection.  These can be used in (e.g.) check_rcpt to
		verify that someone isn't trying to relay mail through your
		host inappropriately.  Be sure to use the deferred evaluation
		form, for example $&{client_name}, to avoid having these bound
		when sendmail reads the configuration file.
	Add new config file rule check_relay to check the incoming connection
		information.  Like check_compat, it is passed the host name
		and host address separated by $| and can reject connections
		on that basis.
	Allow IDA-style recursive function calls.  Code contributed by Mark
		Lovell and Paul Vixie.
	Eliminate the "No ! in UUCP From address!" message" -- instead, create
		a virtual UUCP address using either a domain address or the $k
		macro.  Based on code contributed by Mark Lovell and Paul
		Vixie.
	Add Stanford LDAP map.  Requires special libraries that are not
		included with sendmail.  Contributed by Booker C. Bense
		<bbense@networking.stanford.edu>; contact him for support.
		See also the src/READ_ME file.
	Allow -dANSI to turn on ANSI escape sequences in debug output; this
		puts metasymbols (e.g., $+) in reverse video.  Really useful
		only for debugging deep bits of code where it is important to
		distinguish between the single-character metasymbol $+ and the
		two characters $, +.
	Changed ruleset 89 (executed in dumpstate()) to a named ruleset,
		debug_dumpstate.
	Add new UnsafeGroupWrites option; if set, .forward and :include:
		files that are group writable are considered "unsafe" -- that
		is, programs and files referenced from such files are not
		valid recipients.
	Delete bogosity test for FallBackMX host; this prevented it to be a
		name that was not in DNS or was a domain-literal.  Problem
		noted by Tom May.
	Change the introduction to error messages to more clearly delineate
		permanent from temporary failures; if both existed in a
		single message it could be confusing.  Suggested by John
		Beck of InReference, Inc.
	The IngoreDot (i) option didn't work for lines that were terminated
		with CRLF.  Problem noted by Ted Stockwell of Secure
		Computing Corporation.
	Add a heuristic to improve the handling of unbalanced `<' signs in
		message headers.  Problem reported by Matt Dillon of Best
		Internet Communications.
	Check for bogus characters in the 0200-0237 range; since these are
		used internally, very strange errors can occur if those
		characters appear in headers.  Problem noted by Anders Gertz
		of Lysator.
	Implement 7 -> 8 bit MIME conversions.  This only takes place if the
		recipient mailer has the F=9 flag set, and only works on
		text/plain body types.  Code contributed by Marius Olafsson
		of the University of Iceland.
	Special case "postmaster" name so that it is always treated as lower
		case in alias files regardless of configuration settings;
		this prevents some potential problems where "Postmaster" or
		"POSTMASTER" might not match "postmaster".  In most cases
		this change is a no-op.
	The -o map flag was ignored for text maps.  Problem noted by Bryan
		Costales.
	The -a map flag was ignored for dequote maps.  Problem noted by
		Bryan Costales.
	Fix core dump when a lookup of a class "prog" map returns no
		response.  Patch from Bryan Costales.
	Log instances where sendmail is deferring or rejecting connections
		on LogLevel 14.  Suggested by Kyle Jones of UUNET.
	Include port number in process title for network daemons.  Suggested
		by Kyle Jones of UUNET.
	Send ``double bounces'' (errors that occur when sending an error
		message) to the address indicated in the DoubleBounceAddress
		option (default: postmaster).  Previously they were always
		sent to postmaster.  Suggested by Kyle Jones of UUNET.
	Add new mode, -bD, that acts like -bd in all respects except that
		it runs in foreground.  This is useful for using with a
		wrapper that "watches" system services.  Suggested by Kyle
		Jones of UUNET.
	Fix botch in spacing around (parenthesized) comments in addresses
		when the comment comes before the address.  Patch from
		Motonori Nakamura of Kyoto University.
	Use the prefix "Postmaster notify" on the Subject: lines of messages
		that are being bounced to postmaster, rather than "Returned
		mail".  This permits the person who is postmaster more
		easily determine what messages are to their role as
		postmaster versus bounces to mail they actually sent.  Based
		on a suggestion by Motonori Nakamura.
	Add new value "time" for QueueSortOrder option; this causes the queue
		to be sorted strictly by the time of submission.  Note that
		this can cause very bad behavior over slow lines (because
		large jobs will tend to delay small jobs) and on nodes with
		heavy traffic (because old things in the queue for hosts that
		are down delay processing of new jobs).  Also, this does not
		guarantee that jobs will be delivered in submission order
		unless you also set DeliveryMode=queue.  In general, it should
		probably only be used on the command line, and only in
		conjunction with -qRhost.domain.  In fact, there are very few
		cases where it should be used at all.  Based on an
		implementation by Motonori Nakamura.
	If a map lookup in ruleset 5 returns tempfail, queue the message in
		the same manner as other rulesets.  Previously a temporary
		failure in ruleset 5 was ignored.  Patch from Booker Bense
		of Stanford University.
	Don't proceed to the next MX host if an SMTP MAIL command returns a
		5yz (permanent failure) code.  The next MX host will still be
		tried if the connection cannot be opened in the first place
		or if the MAIL command returns a 4yz (temporary failure) code.
		(It's hard to know what to do here, since neither RFC 974 nor
		RFC 1123 specify when to proceed to the next MX host.)
		Suggested by Jonathan Kamens of OpenVision, Inc.
	Add new "-t" flag for map definitions (the "K" line in the .cf file).
		This causes map lookups that get a temporary failure (e.g.,
		name server failure) to _not_ defer the delivery of the
		message.  This should only be used if your configuration file
		is prepared to do something sensible in this case.  Based on
		an idea by Gregory Shapiro of WPI.
	Fix problem finding network interface addresses.  Patch from
		Motonori Nakamura.
	Don't reject qf entries that are not owned by your effective uid if
		you are not running set-user-ID; this makes management of
		certain kinds of firewall setups difficult.  Patch
		suggested by Eamonn Coleman of Qualcomm.
	Add persistent host status.  This keeps the information normally
		maintained within a single queue run in disk files that are
		shared between sendmail instances.  The HostStatusDirectory
		is the directory in which the information is maintained.  If
		not set, persistent host status is turned off.  If not a full
		pathname, it is relative to the queue directory.  A common
		value is ".hoststat".
		There are also two new operation modes:
		  * -bh prints the status of hosts that have had recent
		    connections.
		  * -bH purges the host statuses.  No attempt is made to save
		    recent status information.
		This feature was originally written by Paul Vixie of Vixie
		Enterprises for KJS and adapted for V8 by Mark Lovell of
		Bigrock Consulting.  Paul's funding of Mark and Mark's patience
		with my insistence that things fit cleanly into the V8
		framework is gratefully appreciated.
	New SingleThreadDelivery option (requires HostStatusDirectory to
		operate).  Avoids letting two sendmails on the local machine
		open connections to the same remote host at the same time.
		This reduces load on the other machine, but can cause mail to
		be delayed (for example, if one sendmail is delivering a huge
		message, other sendmails won't be able to send even small
		messages).  Also, it requires another file descriptor (for the
		lock file) per connection, so you may have to reduce
		ConnectionCacheSize to avoid running out of per-process
		file descriptors.  Based on the persistent host status code
		contributed by Paul Vixie and Mark Lovell.
	Allow sending to non-simple files (e.g., /dev/null) even if the
		SafeFileEnvironment option is set.  Problem noted by Bryan
		Costales.
	The -qR flag mistakenly matched flags in the "R" line of the queue
		file.  Problem noted by Bryan Costales.
	If a job was aborted using the interrupt signal (e.g., control-C from
		the keyboard), on some occasions an empty df file would be
		left around; these would collect in the queue directory.
		Problem noted by Bryan Costales.
	Change the makesendmail script to enhance the search for Makefiles
		based on release number.  For example, on SunOS 5.5.1, it will
		search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then
		Makefile.SunOS.5.x (in addition to the other rules, e.g.,
		adding $arch).  Problem noted by Jason Mastaler of Atlanta
		Webmasters.
	When creating maps using "newaliases", always map the keys to lower
		case when creating the map unless the -f flag is specified on
		the map itself.  Previously this was done based on the F=u
		flag in the local mailer, which meant you could create aliases
		that you could never access.  Problem noted by Bob Wu of DEC.
	When a job was read from the queue, the bits causing notification on
		failure or delay were always set.  This caused those
		notifications to be sent even if NOTIFY=NEVER had been
		specified.  Problem noted by Steve Hubert of the University
		of Washington, Seattle.
	Add new configurable routine validate_connection (in conf.c).  This
		lets you decide if you are willing to accept traffic from
		this host.  If it returns FALSE, all SMTP commands will return
		"550 Access denied".  -DTCPWRAPPERS will include support for
		TCP wrappers; you will need to add -lwrap to the link line.
		(See src/READ_ME for details.)
	Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster
		bounces.  Some people seemed to think that this could be
		confusing (even though it is true).  Suggested by Motonori
		Nakamura.
	Add new RunAsUser option; this causes sendmail to do a setuid to that
		user early in processing to avoid potential security problems.
		However, this means that all .forward and :include: files must
		be readable by that user, and all files to be written must be
		writable by that user and all programs will be executed by that
		user.  It is also incompatible with the SafeFileEnvironment
		option.  In other words, it may not actually add much to
		security.  However, it should be useful on firewalls and other
		places where users don't have accounts and the aliases file is
		well constrained.
	Add Timeout.iconnect.  This is like Timeout.connect except it is used
		only on the first attempt to delivery to an address.  It could
		be set to be lower than Timeout.connect on the principle that
		the mail should go through quickly to responsive hosts; less
		responsive hosts get to wait for the next queue run.
	Fix a problem on Solaris that occasionally causes programs
		(such as vacation) to hang with their standard input connected
		to a UDP port.  It also created some signal handling problems.
		The problems turned out to be an interaction between vfork(2)
		and some of the libraries, particularly NIS/NIS+.  I am
		indebted to Tor Egge <tegge@idt.ntnu.no> for this fix.
	Change user class map to do the same matching that actual delivery
		will do instead of just a /etc/passwd lookup.  This adds
		fuzzy matching to the user map.  Patch from Dan Oscarsson.
	The Timeout.* options are not safe -- they can be used to create a
		denial-of-service attack.  Problem noted by Christophe
		Wolfhugel.
	Don't send PostmasterCopy messages in the event of a "delayed"
		notification.  Suggested by Barry Bouwsma.
	Don't advertise "VERB" ESMTP extension if the "noexpn" privacy
		option is set, since this disables VERB mode.  Suggested
		by John Hawkinson of MIT.
	Complain if the QueueDirectory (Q) option is not set.  Problem noted
		by Motonori Nakamura of Kyoto University.
	Only queue messages on transient .forward open failures if there
		were no successful opens.  The previous behavior caused it
		to queue even if a "fall back" .forward was found.  Problem
		noted by Ann-Kian Yeo of the Dept. of Information Systems
		and Computer Science (DISCS), NUS, Singapore.
	Don't do 8->7 bit conversions when bouncing a MIME message that
		is bouncing because of a MIME error during 8->7 bit conversion;
		the encapsulated message will bounce again, causing a loop.
		Problem noted by Steve Hubert of the University of Washington.
	Create xf (transcript) files using the TempFileMode option value
		instead of 0644.  Suggested by Ann-Kian Yeo of the
		National University of Singapore.
	Print errors if setgid/setuid/etc. fail during delivery.  This helps
		detect cases where DefaultUid is set to something that the
		system can't cope with.

	CONFIG: add generic-nextstep3.3.mc file.  Contributed by
		Robert La Ferla of Hot Software.
	CONFIG: allow mailertables to resolve to ``error:code message''
		(where "code" is an exit status) on domains (previously
		worked only on hosts).  Patch from Cor Bosman of Xs4all
		Foundation.
	CONFIG: hooks for IPv6-style domain literals.
	CONFIG: predefine ALIAS_FILE and change the prototype file so that
		if it is undefined the AliasFile option is never set; this
		should be transparent for most everyone.  Suggested by John
		Myers of CMU.
	CONFIG: add FEATURE(limited_masquerade).  Without this feature, any
		domain listed in $=w is masqueraded.  With it, only those
		domains listed in a MASQUERADE_DOMAIN macro are masqueraded.
	CONFIG: add FEATURE(masquerade_entire_domain).  This causes
		masquerading specified by MASQUERADE_DOMAIN to apply to all
		hosts under those domains as well as the domain headers
		themselves.  For example, if a configuration had
		MASQUERADE_DOMAIN(foo.com), then without this feature only
		foo.com would be masqueraded; with it, *.foo.com would be
		masqueraded as well.  Based on an implementation by Richard
		(Pug) Bainter of U. Texas.
	CONFIG: add FEATURE(genericstable) to do a more general rewriting of
		outgoing addresses.  Defaults to ``hash -o /etc/genericstable''.
		Keys are user names; values are outgoing mail addresses.  Yes,
		this does overlap with the user database, and figuring out
		just when to use which one may be tricky.  Based on code
		contributed by Richard (Pug) Bainter of U. Texas with updates
		from Per Hedeland of Ericsson.
	CONFIG: add FEATURE(virtusertable) to do generalized rewriting of
		incoming addresses.  Defaults to ``hash -o /etc/virtusertable''.
		Keys are either fully qualified addresses or just the host
		part (with the @ sign).  For example, a table containing:
			info@foo.com	foo-info
			info@bar.com	bar-info
			@baz.org	jane@elsewhere.net
		would send all mail destined for info@foo.com to foo-info
		(which is presumably an alias), mail addressed to info@bar.com
		to bar-info, and anything addressed to anyone at baz.org will
		be sent to jane@elsewhere.net.  The names foo.com, bar.com,
		and baz.org must all be in $=w.  Based on discussions with
		a great many people.
	CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS.
		Suggested by Richard Bainter.
	CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the
		"fax" mailer.
	CONFIG: allow mailertable entries to resolve to local:user; this
		passes the original user@host in to procmail-style local
		mailers as the "detail" information to allow them to do
		additional clever processing.  From Joe Pruett of
		Teleport Corporation.  Delivery to the original user can
		be done by specifying "local:" (with nothing after the colon).
	CONFIG: allow any context that takes "mailer:domain" to also take
		"mailer:user@domain" to force mailing to the given user;
		"local:user" can also be used to do local delivery.  This
		applies on *_RELAY and in the mailertable entries.  Based
		on a suggestion by Ribert Kiessling of Easynet.
	CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that
		limits the possible domains; this reduces the number of DNS
		lookups required to support this feature.  For example,
		FEATURE(bestmx_is_local, my.site.com) limits the lookups
		to domains under my.site.com.  Code contributed by Anthony
		Thyssen <anthony@cit.gu.edu.au>.
	CONFIG: LOCAL_RULESETS introduces any locally defined rulesets,
		such as the check_rcpt ruleset.  Suggested by Gregory Shapiro
		of WPI.
	CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the
		event you have to define local mailers.  Suggested by
		Gregory Shapiro of WPI.
	CONFIG: fix cases where a three- (or more-) stage route-addr could
		be misinterpreted as a list:...; syntax.  Based on a patch by
		Vlado Potisk <Vlado_Potisk@tempest.sk>.
	CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is
		remotely connected.  The address host!user was being
		converted to host!user@thishost instead of host!user@uurelay.
		Problem noted by William Gianopoulos of Raytheon Company.
	CONFIG: add confTO_ICONNECT to set Timeout.iconnect.
	CONFIG: change FEATURE(redirect) message from "User not local" to
		"User has moved"; the former wording was confusing if the
		new address is still on the local host.  Based on a suggestion
		by Andreas Luik.
	CONFIG: add support in FEATURE(nullclient) for $=E (exposed users).
		However, the class is not pre-initialized to contain root.
		Suggested by Gregory Neil Shapiro.
	CONTRIB: Remove XLA code at the request of the author, Christophe
		Wolfhugel.
	CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm.
	MAIL.LOCAL: make it possible to compile mail.local on Solaris.  Note
		well: this produces a slightly different mailbox format (no
		Content-Length: headers), file ownerships and modes are
		different (not owned by group mail; mode 600 instead of 660),
		and the local mailer flags will have to be tweaked (make them
		match bsd4.4) in order to use this mailer.  Patches from Paul
		Hammann of the Missouri Research and Education Network.
	MAIL.LOCAL: in some cases it could return EX_OK even though there
		was a delivery error, such as if the ownership on the file
		was wrong or the mode changed between the initial stat and
		the open.  Problem reported by William Colburn of the New
		Mexico Institute of Mining and Technology.
	MAILSTATS: handle zero length files more reliably.  Patch from Bryan
		Costales.
	MAILSTATS: add man page contributed by Keith Bostic of BSDI.
	MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't
		honored.  Fix from Michael Scott Shappe.
	PRALIASES: add man page contributed by Keith Bostic of BSDI.

8.7.6/8.7.3	1996/09/17
	SECURITY: It is possible to force getpwuid to fail when writing the
		queue file, causing sendmail to fall back to running programs
		as the default user.  This is not exploitable from off-site.
		Workarounds include using a unique user for the DefaultUser
		(old u & g options) and using smrsh as the local shell.
	SECURITY: fix some buffer overruns; in at least one case this allows
		a local user to get root.  This is not known to be exploitable
		from off-site.  The workaround is to disable chfn(1) commands.

8.7.5/8.7.3	1996/03/04
	Fix glitch in 8.7.4 when putting certain internal lines; this can
		in some case cause connections to hang or messages to have
		extra spaces in odd places.  Patch from Eric Wassenaar;
		reports from Eric Hall of Chiron Corporation, Stephen
		Hansen of Stanford University, Dean Gaudet of HotWired,
		and others.

8.7.4/8.7.3	1996/02/18
	SECURITY: In some cases it was still possible for an attacker to
		insert newlines into a queue file, thus allowing access to
		any user (except root).
	CONFIG: no changes -- it is not a bug that the configuration
		version number is unchanged.

8.7.3/8.7.3	1995/12/03
	Fix botch in name server timeout in RCPT code; this problem caused
		two responses in SMTP, which breaks things horribly.  Fix
		from Gregory Neil Shapiro of WPI.
	Verify that L= value on M lines cannot be negative, which could cause
		negative array subscripting.  Not a security problem since
		this has to be in the config file, but it could have caused
		core dumps.  Pointed out by Bryan Costales.
	Fix -d21 debug output for long macro names.  Pointed out by Bryan
		Costales.
	PORTABILITY FIXES:
		SCO doesn't have ftruncate.  From Bill Aten of Computerizers.
		IBM's version of arpa/nameser.h defaults to the wrong byte
			order.  Tweak it to work properly.  Based on fixes
			from Fletcher Mattox of UTexas and Betty Lee of
			Stanford University.
	CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option.
		Deficiency pointed out by Bryan Costales of ICSI.

8.7.2/8.7.2	1995/11/19
	REALLY fix the backslash escapes in SmtpGreetingMessage,
		OperatorChars, and UnixFromLine options.  They were not
		properly repaired in 8.7.1.
	Completely delete the Bcc: header if and only if there are other
		valid recipient headers (To:, Cc: or Apparently-To:, the
		last being a historic botch, of course).  If Bcc: is the
		only recipient header in the message, its value is tossed,
		but the header name is kept.  The old behavior (always keep
		the header name and toss the value) allowed primary recipients
		to see that a Bcc: went to _someone_.
	Include queue id on ``Authentication-Warning: <host>: <user> set
		sender to <address> using -f'' syslog messages.  Suggested
		by Kari Hurtta.
	If a sequence or switch map lookup entry gets a tempfail but then
		continues on to another map type, but the name is not found,
		return a temporary failure from the sequence or switch map.
		For example, if hosts search ``dns files'' and DNS fails
		with a tempfail, the hosts map will go on and search files,
		but if it fails the whole thing should be a tempfail, not
		a permanent (host unknown) failure, even though that is the
		failure in the hosts.files map.  This error caused hard
		bounces when it should have requeued.
	Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo
		owned by bar mode 700 and inbox being set-user-ID bar stopped
		working properly due to excessive paranoia.  Pointed out by
		John Hawkinson of Panix.
	An SMTP RCPT command referencing a host that gave a nameserver
		timeout would return a 451 command (8.6 accepted it and
		queued it locally).  Revert to the 8.6 behavior in order
		to simplify queue management for clustered systems.  Suggested
		by Gregory Neil Shapiro of WPI.  The same problem could break
		MH, which assumes that the SMTP session will succeed (tsk, tsk
		-- mail gets lost!); this was pointed out by Stuart Pook of
		Infobiogen.
	Fix possible buffer overflow in munchstring().  This was not a security
		problem because you couldn't specify any argument to this
		without first giving up root privileges, but it is still a
		good idea to avoid future problems.  Problem noted by John
		Hawkinson and Sam Hartman of MIT.
	``452 Out of disk space for temp file'' messages weren't being
		printed.  Fix from David Perlin of Nanosoft.
	Don't advertise the ESMTP DSN extension if the SendMimeErrors option
		is not set, since this is required to get the actual DSNs
		created.  Problem pointed out by John Gardiner Myers of CMU.
	Log permission problems that cause .forward and :include: files to
		be untrusted or ignored on log level 12 and higher.  Suggested
		by Randy Martin of Clemson University.
	Allow user ids in U= clauses of M lines to have hyphens and
		underscores.
	Fix overcounting of recipients -- only happened when sending to an
		alias.  Pointed out by Mark Andrews of SGI and Jack Woolley
		of Systems and Computer Technology Corporation.
	If a message is sent to an address that fails, the error message that
		is returned could show some extraneous "success" information
		included even if the user did not request success notification,
		which was confusing.  Pointed out by Allan Johannesen of WPI.
	Config files that had no AliasFile definition were defaulting to
		using /etc/aliases; this caused problems with nullclient
		configurations.  Change it back to the 8.6 semantics of
		having no local alias file unless it is declared.  Problem
		noted by Charles Karney of Princeton University.
	Fix compile problem if NOTUNIX is defined.  Pointed out by Bryan
		Costales of ICSI.
	Map lookups of class "userdb" maps were always case sensitive; they
		should be controlled by the -f flag like other maps.  Pointed
		out by Bjart Kvarme <bjart.kvarme@usit.uio.no>.
	Fix problem that caused some addresses to be passed through ruleset 5
		even when they were tagged as "sticky" by prefixing the
		address with an "@".  Patch from Thomas Dwyer III of Michigan
		Technological University.
	When converting a message to Quoted-Printable, prevent any lines with
		dots alone on a line by themselves.  This is because of the
		preponderance of broken mailers that still get this wrong.
		Code contributed by Per Hedeland of Ericsson.
	Fix F{macro}/file construct -- it previously did nothing.  Pointed
		out by Bjart Kvarme of USIT/UiO (Norway).
	Announce whether a cached connection is SMTP or ESMTP (in -v mode).
		Requested by Allan Johannesen.
	Delete check for text format of alias files -- it should be legal
		to have the database format of the alias files without the
		text version.  Problem pointed out by Joe Rhett of Navigist,
		Inc.
	If "Ot" was specified with no value, the TZ variable was not properly
		imported from the environment.  Pointed out by Frank Crawford
		<frank@ansto.gov.au>.
	Some architectures core dumped on "program" maps that didn't have
		extra arguments.  Patch from Booker C. Bense of Stanford
		University.
	Queue run processes would re-spawn daemons when given a SIGHUP; only
		the parent should do this.  Fix from Brian Coan of the
		Association for Progressive Communications.
	If MinQueueAge was set and a message was considered but not run
		during a queue run and the Timeout.queuereturn interval was
		reached, a "timed out" error message would be returned that
		didn't include the failed address (and claimed to be a warning
		even though it was fatal).  The fix is to not return such
		messages until they are actually tried, i.e., in the next
		MinQueueAge interval.  Problem noted by Rein Tollevik of
		SINTEF RUNIT, Oslo.
	Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions
		that have the hes_getmailhost() routine.  DEC Hesiod
		distributions do not have this routine.  Based on a patch
		from Betty Lee of Stanford University.
	Extensive cleanups to map open code to handle a locking race condition
		in ndbm, hash, and btree format database files on some (most
		non-4.4-BSD based) OS architectures.  This should solve the
		occasional "user unknown" problem during alias rebuilds that
		has plagued me for quite some time.  Based on a patch from
		Thomas Dwyer III of Michigan Technological University.
	PORTABILITY FIXES:
		Solaris: Change location of newaliases and mailq from
			/usr/ucb to /usr/bin to match Sun settings.  From
			James B. Davis of TCI.
		DomainOS: Makefile.DomainOS doesn't require -ldbm.  From
			Don Lewis of Silicon Systems.
		HP-UX 10: rename Makefile.HP-UX.10 => Makefile.HP-UX.10.x
			so that the makesendmail script will find it.  Pointed
			out by Richard Allen of the University of Iceland.
			Also, use -Aa -D_HPUX_SOURCE instead of -Ae, which
			isn't supported on all compilers.
		UXPDS: compilation fixes from Diego R. Lopez.
	CONFIG: FAX mailer wasn't setting .FAX as a pseudo-domain unless
		you also had a FAX_RELAY.  From Thomas.Tornblom@Hax.SE.
	CONFIG: Minor glitch in S21 -- attachment of local domain name
		didn't have trailing dot.  From Jim Hickstein of Teradyne.
	CONFIG: Fix best_mx_is_local feature to allow nested addresses such as
		user%host@thishost.  From Claude Scarpelli of Infobiogen
		(France).
	CONFIG: OSTYPE(hpux10) failed to define the location of the help file.
		Pointed out by Hannu Martikka of Nokia Telecommunications.
	CONFIG: Diagnose some inappropriate ordering in configuration files,
		such as FEATURE(smrsh) listed after MAILER(local).  Based on
		a bug report submitted by Paul Hoffman of Proper Publishing.
	CONFIG: Make OSTYPE files consistently not override settings that
		have already been set.  Previously it worked differently
		for different files.
	CONFIG: Change relay mailer to do masquerading like 8.6 did.  My take
		is that this is wrong, but the change was causing problems
		for some people.  From Per Hedeland of Ericsson.
	CONTRIB: bitdomain.c patch from John Gardiner Myers <jgm+@CMU.EDU>;
		portability changes for Posix environments (no functional
		changes).

8.7.1/8.7.1	1995/10/01
	Old macros that have become options (SmtpGreetingMessage,
		OperatorChars, and UnixFromLine) didn't allow backslash
		escapes in the options, where they previously had.  Bug
		pointed out by John Hawkinson of MIT.
	Fix strange case of an executable called by a program map that
		returns a value but also a non-zero exit status; this
		would give contradictory results in the higher level; in
		particular, the default clause in the map lookup would be
		ignored.  Change to ignore the value if the program returns
		non-zero exit status.  From Tom Moore of AT&T GIS.
	Shorten parameters passed to syslog() in some contexts to avoid a
		bug in many vendors' implementations of that routine.  Although
		this isn't really a bug in sendmail per se, and my solution
		has to assume that syslog() has at least a 1K buffer size
		internally (I know some vendors have shortened this
		dramatically -- they're on their own), sendmail is a popular
		target.  Also, limit the size of %s arguments in sprintf.
		These both have possible security implications.  Solutions
		suggested by Casper Dik of Sun's Network Security Group
		(Holland), Mark Seiden, and others.
	Fix a problem that might cause a non-standard -B (body type)
		parameter to be passed to the next server with undefined
		results.  This could have security implications.
	If a filesystem was at > 100% utilization, the freediskspace()
		routine incorrectly returned an error rather than zero.
		Problem noted by G. Paul Ziemba of Alantec.
	Change MX sort order so that local hostnames (those in $=w) always
		sort first within a given preference.  This forces the bestmx
		map to always return the local host first, if it is included
		in the list of highest priority MX records.  From K. Robert
		Elz.
	Avoid some possible null pointer dereferences.  Fixes from Randy
		Martin <WOLF@CLEMSON.EDU>
	When sendmail starts up on systems that have no fully qualified
		domain name (FQDN) anywhere in the first matching host map
		(e.g., /etc/hosts if the hosts service searches "files dns"),
		sendmail would sleep to try to find a FQDN, which it really
		really needs.  This has been changed to fall through to the
		next map type if it can't find a FQDN -- i.e., if the hosts
		file doesn't have a FQDN, it will try dns even though the
		short name was found in /etc/hosts.  This is probably a crock,
		but many people have hosts files without FQDNs.  Remember:
		domain names are your friends.
	Log a high-priority message if you can't find your FQDN during startup.
		Suggested by Simon Barnes of Schlumberger Limited.
	When using Hesiod, initialize it early to improve error reporting.
		Patch from Don Lewis of Silicon Systems, Inc.
	Apparently at least some versions of Linux have a 90 !minute! TCP
		connection timeout in the kernel.  Add a new "connect" timeout
		to limit this time.  Defaults to zero (use whatever the
		kernel provides).  Based on code contributed by J.R. Oldroyd
		of TerraNet.
	Under some circumstances, a failed message would not be properly
		removed from the queue, causing tons of bogus error messages.
		(This fix eliminates the problematic EF_KEEPQUEUE flag.)
		Problem noted by Allan E Johannesen and Gregory Neil Shapiro
		of WPI.
	PORTABILITY FIXES:
		On IRIX 5.x, there was an inconsistency in the setting
			of sendmail.st location.  Change the Makefile to
			install it in /var/sendmail.st to match the OSTYPE
			file and SGI standards.  From Andre
			<andre@curry.zfe.siemens.de>.
		Support for Fujitsu/ICL UXP/DS (For the DS/90 Series)
			from Diego R. Lopez <drlopez@cica.es>.
		Linux compilation patches from J.R. Oldroyd of TerraNet, Inc.
		LUNA 2 Mach patches from Motonori Nakamura.
		SunOS Makefile was including -ldbm, which is for the old
			dbm library.  The ndbm library is part of libc.
	CONFIG: avoid bouncing ``user@host.'' (note trailing dot) with
		``local configuration error'' in nullclient configuration.
		Patch from Gregory Neil Shapiro of WPI.
	CONFIG: don't allow an alias file in nullclient configurations --
		since all addresses are relayed, they give errors during
		rebuild.  Suggested by Per Hedeland of Ericsson.
	CONFIG: local mailer on Solaris 2 should always get a -f flag because
		otherwise the F=S causes the From_ line to imply that root is
		the sender.  Problem pointed out by Claude Scarpelli of
		Infobiogen (France).
	NEW FILES:
		cf/feature/use_ct_file.m4 (omitted from 8.7 by mistake)
		src/Makefiles/Makefile.KSR (omitted from 8.7 by mistake)
		src/Makefiles/Makefile.UXPDS

8.7/8.7		1995/09/16
	Fix a problem that could cause sendmail to run out of file
		descriptors due to a trashed data structure after a
		vfork.  Fix from Brian Coan of the Institute for
		Global Communications.
	Change the VRFY response if you have disabled VRFY -- some
		people seemed to think that it was too rude.
	Avoid reference to uninitialized file descriptor if HASFLOCK
		was not defined.  This was used "safely" in the sense
		that it only did a stat, but it would have set the
		map modification time improperly.  Problem pointed out
		by Roy Mongiovi of Georgia Tech.
	Clean up the Subject: line on warning messages and return
		receipts so that they don't say "Returned mail:"; this
		can be confusing.
	Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is
		useful enough to make it worthwhile printing on "-d".
	Avoid logging alias statistics every time you read the alias
		file on systems with no database method compiled in.
	If you have a name with a trailing dot, and you try looking it
		up using gethostbyname without the dot (for /etc/hosts
		compatibility), be sure to turn off RES_DEFNAMES and
		RES_DNSRCH to avoid finding the wrong name accidentally.
		Problem noted by Charles Amos of the University of
		Maryland.
	Don't do timeouts in collect if you are not running SMTP.
		There is nothing that says you can't have a long
		running program piped into sendmail (possibly via
		/bin/mail, which just execs sendmail).  Problem reported
		by Don "Truck" Lewis of Silicon Systems.
	Try gethostbyname() even if the DNS lookup fails iff option I
		is not set.  This allows you to have hosts listed in
		NIS or /etc/hosts that are not known to DNS.  It's normally
		a bad idea, but can be useful on firewall machines.  This
		should really be broken out on a separate flag, I suppose.
	Avoid compile warnings against BIND 4.9.3, which uses function
		prototypes.  From Don Lewis of Silicon Systems.
	Avoid possible incorrect diagnosis of DNS-related errors caused
		by things like attempts to resolve uucp names using
		$[ ... $] -- the fix is to clear h_errno at appropriate
		times.  From Kyle Jones of UUNET.
	SECURITY: avoid denial-of-service attacks possible by destroying
		the alias database file by setting resource limits low.
		This involves adding two new compile-time options:
		HASSETRLIMIT (indicating that setrlimit(2) support is
		available) and HASULIMIT (indicating that ulimit(2) support
		is available -- the Release 3 form is used).  The former
		is assumed on BSD-based systems, the latter on System
		V-based systems.  Attack noted by Phil Brandenberger of
		Swarthmore University.
	New syntaxes in test (-bt) mode:
		``.Dmvalue'' will define macro "m" to "value".
		``.Ccvalue'' will add "value" to class "c".
		``=Sruleset'' will dump the contents of the indicated
			ruleset.
		``=M'' will display the known mailers.
		``-ddebug-spec'' is equivalent to the command-line
			-d debug flag.
		``$m'' will print the value of macro $m.
		``$=c'' will print the contents of class $=c.
		``/mx host'' returns the MX records for ``host''.
		``/parse address'' will parse address, returning the value of
			crackaddr (essentially, the comment information)
			and the parsed address.
		``/try mailer address'' will rewrite address into the form
			it will have when presented to the indicated mailer.
		``/tryflags flags'' will set flags used by parsing.  The
			flags can be `H' for header or `E' for envelope,
			and `S' for sender or `R' for recipient.  These
			can be combined, so `HR' sets flags for header
			recipients.
		``/canon hostname'' will try to canonify hostname and
			return the result.
		``/map mapname key'' will look up `key' in the indicated
			`mapname' and return the result.
	Somewhat better handling of UNIX-domain socket addresses -- it
		should show the pathname rather than hex bytes.
	Restore ``-ba'' mode -- this reads a file from stdin and parses
		the header for envelope sender information and uses
		CR-LF as message terminators.  It was thought to be
		obsolete (used only for Arpanet NCP protocols), but it
		turns out that the UK ``Grey Book'' protocols require
		that functionality.
	Fix a fix in previous release -- if gethostname and gethostbyname
		return a name without dots, and if an attempt to canonify
		that name fails, wait one minute and try again.  This can
		result in an extra 60 second delay on startup if your system
		hostname (as returned by hostname(1)) has no dot and no names
		listed in /etc/hosts or your NIS map have a dot.
	Check for proper domain name on HELO and EHLO commands per
		RFC 1123 section 5.2.5.  Problem noted by Thomas Dwyer III
		of Michigan Technological University.
	Relax chownsafe rules slightly -- old version said that if you
		can't tell if _POSIX_CHOWN_RESTRICTED is set (that is,
		if fpathconf returned EINVAL or ENOSYS), assume that
		chown is not safe.  The new version falls back to whether
		you are on a BSD system or not.  This is important for
		SunOS, which apparently always returns one of those
		error codes.  This impacts whether you can mail to files
		or not.
	Syntax errors such as unbalanced parentheses in the configuration
		file could be omitted if you had "Oem" prior to the
		syntax error in the config file.  Change to always print
		the error message.  It was especially weird because it
		would cause a "warning" message to be sent to the Postmaster
		for every message sent (but with no transcript).  Problem
		noted by Gregory Paris of Motorola.
	Rewrite collect and putbody to handle full 8-bit data, including
		zero bytes.  These changes are internally extensive, but
		should have minimal impact on external function.
	Allow full words for option names -- if the option letter is
		(apparently) a space, then take the word following -- e.g.,
			O MatchGECOS=TRUE
		The full list of old and new names is as follows:
			7	SevenBitInput
			8	EightBitMode
			A	AliasFile
			a	AliasWait
			B	BlankSub
			b	MinFreeBlocks/MaxMessageSize
			C	CheckpointInterval
			c	HoldExpensive
			D	AutoRebuildAliases
			d	DeliveryMode
			E	ErrorHeader
			e	ErrorMode
			f	SaveFromLine
			F	TempFileMode
			G	MatchGECOS
			H	HelpFile
			h	MaxHopCount
			i	IgnoreDots
			I	ResolverOptions
			J	ForwardPath
			j	SendMimeErrors
			k	ConnectionCacheSize
			K	ConnectionCacheTimeout
			L	LogLevel
			l	UseErrorsTo
			m	MeToo
			n	CheckAliases
			O	DaemonPortOptions
			o	OldStyleHeaders
			P	PostmasterCopy
			p	PrivacyOptions
			Q	QueueDirectory
			q	QueueFactor
			R	DontPruneRoutes
			r, T	Timeout
			S	StatusFile
			s	SuperSafe
			t	TimeZoneSpec
			u	DefaultUser
			U	UserDatabaseSpec
			V	FallbackMXHost
			v	Verbose
			w	TryNullMXList
			x	QueueLA
			X	RefuseLA
			Y	ForkEachJob
			y	RecipientFactor
			z	ClassFactor
			Z	RetryFactor
		The old macros that passed information into sendmail have
		been changed to options; those correspondences are:
			$e	SmtpGreetingMessage
			$l	UnixFromLine
			$o	OperatorChars
			$q	(deleted -- not necessary)
		To avoid possible problems with an older sendmail,
		configuration level 6 is accepted by this version of
		sendmail; any config file using the new names should
		specify "V6" in the configuration.
	Change address parsing to properly note that a phrase before a
		colon and a trailing semicolon are essentially the same
		as text outside of angle brackets (i.e., sendmail should
		treat them as comments).  This is to handle the
		``group name: addr1, addr2, ..., addrN;'' syntax (it will
		assume that ``group name:'' is a comment on the first
		address and the ``;'' is a comment on the last address).
		This requires config file support to get right.  It does
		understand that :: is NOT this syntax, and can be turned
		off completely by setting the ColonOkInAddresses option.
	Level 6 config files added with new mailer flags:
		    A	Addresses are aliasable.
		    i	Do udb rewriting on envelope as well as header
			sender lines.  Applies to the from address mailer
			flags rather than the recipient mailer flags.
		    j	Do udb rewriting on header recipient addresses.
			Applies to the sender mailer flags rather than the
			recipient mailer flags.
		    k	Disable check for loops when doing HELO command.
		    o	Always run as the mail recipient, even on local
			delivery.
		    w	Check for an /etc/passwd entry for this user.
		    5	Pass addresses through ruleset 5.
		    :	Check for :include: on this address.
		    |	Check for |program on this address.
		    /	Check for /file on this address.
		    @	Look up sender header addresses in the user
			database.  Applies to the mailer flags for the
			mailer corresponding to the envelope sender
			address, rather than to recipient mailer flags.
		Pre-level 6 configuration files set A, w, 5, :, |, /, and @
		on the "local" mailer, the o flag on the "prog" and "*file*"
		mailers, and the ColonOkInAddresses option.
	Eight-to-seven bit MIME conversions.  This borrows ideas from
		John Beck of Hewlett-Packard, who generously contributed
		their implementation to me, which I then didn't use (see
		mime.c for an explanation of why).  This adds the
		EightBitMode option (a.k.a. `8') and an F=8 mailer flag
		to control handling of 8-bit data.  These have to cope with
		two types of 8-bit data: unlabelled 8-bit data (that is,
		8-bit data that is entered without declaring it as 8-bit
		MIME -- technically this is illegal according to the
		specs) and labelled 8-bit data (that is, it was declared
		as 8BITMIME in the ESMTP session or by using the
		-B8BITMIME command line flag).  If the F=8 mailer flag is
		set then 8-bit data is sent to non-8BITMIME machines
		instead of converting to 7 bit (essentially using
		just-send-8 semantics).  The values for EightBitMode are:
		    m	convert unlabelled 8-bit input to 8BITMIME, and do
			any necessary conversion of 8BITMIME to 7BIT
			(essentially, the full MIME option).
		    p	pass unlabelled 8-bit input, but convert labelled
			8BITMIME input to 7BIT as required (default).
		    s	strict adherence: reject unlabelled 8-bit input,
			convert 8BITMIME to 7BIT as required.  The F=8
			flag is ignored.
		Unlabelled 8-bit data is rejected in mode `s' regardless of
			the setting of F=8.
	Add new internal class 'n', which is the set of MIME Content-Types
		which can not be 8 to 7 bit encoded because of other
		considerations.  Types "multipart/*" and "message/*" are
		never directly encoded (although their components can be).
	Add new internal class 's', which is the set of subtypes of the
		MIME message/* content type that can be treated as though
		they are an RFC822 message.  It is predefined to have
		"rfc822".  Suggested By Kari Hurtta.
	Add new internal class 'e'.  This is the set of MIME
		Content-Transfer-Encodings that can be converted to
		a seven bit format (Quoted-Printable or Base64).  It is
		preinitialized to contain "7bit", "8bit", and "binary".
	Add C=charset mailer parameter and the the DefaultCharSet option (no
		short name) to set the default character set to use in the
		Content-Type: header when doing encoding of an 8-bit message
		which isn't marked as MIME into MIME format.  If the C=
		parameter is set on the Envelope From address, use that as
		the default encoding; else use the DefaultCharSet option.
		If neither is set, it defaults to "unknown-8bit" as
		suggested by RFC 1428 section 3.
	Allow ``U=user:group'' field in mailer definition to set a default
		user and group that a mailer will be executed as.  This
		overrides the 'u' and 'g' options, and if the `F=S' flag is
		also set, it is the uid/gid that will always be used (that
		is, the controlling address is ignored).  The values may be
		numeric or symbolic; if only a symbolic user is given (no
		group) that user's default group in the passwd file is used
		as the group.  Based on code donated by Chip Rosenthal of
		Unicom.
	Allow `u' option to also accept user:group as a value, in the same
		fashion as the U= mailer option.
	Add the symbolic time zone name in the Arpanet format dates (as
		a comment).  This adds a new compile-time configuration
		flag: TZ_TYPE can be set to TZ_TM_NAME (use the value
		of (struct tm *)->tm_name), TZ_TM_ZONE (use the value
		of (struct tm *)->tm_zone), TZ_TZNAME (use extern char
		*tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use
		timezone()), or TZ_NONE (don't include the comment).  Code
		from Chip Rosenthal.
	The "Timeout" option (formerly "r") is extended to allow suboptions.
		For example,
		    O Timeout.helo = 2m
		There are also two new suboptions "queuereturn" and
		"queuewarn"; these subsume the old T option.  Thus, to
		set them both the preferred new syntax is
		    O Timeout.queuereturn = 5d
		    O Timeout.queuewarn = 4h
	Sort queue by host name instead of by message priority if the
		QueueSortOrder option (no short name) is set is set to
		``host''.  This makes better use of the connection cache,
		but may delay more ``interactive'' messages behind large
		backlogs under some circumstances.  This is probably a
		good option if you have high speed links or don't do lots
		of ``batch'' messages, but less good if you are using
		something like PPP on a 14.4 modem.  Based on code
		contributed by Roy Mongiovi of Georgia Tech (my main
		contribution was to make it configurable).
	Save i-number of df file in qf file to simplify rebuilding of queue
		after disastrous disk crash.  Suggested by Kyle Jones of
		UUNET; closely based on code from KJS DECWRL code written
		by Paul Vixie.  NOTA BENE: The qf files produced by 8.7
		are NOT back compatible with 8.6 -- that is, you can convert
		from 8.6 to 8.7, but not the other direction.
	Add ``F=d'' mailer flag to disable all use of angle brackets in
		route-addrs in envelopes; this is because in some cases
		they can be sent to the shell, which interprets them as
		I/O redirection.
	Don't include error file (option E) with return-receipts; this
		can be confusing.
	Don't send "Warning: cannot send" messages to owner-* or
		*-request addresses.  Suggested by Christophe Wolfhugel
		of the Institut Pasteur, Paris.
	Allow -O command line flag to set long form options.
	Add "MinQueueAge" option to set the minimum time between attempts
		to run the queue.  For example, if the queue interval
		(-q value) is five minutes, but the minimum queue age
		is fifteen minutes, jobs won't be tried more often than
		once every fifteen minutes.  This can be used to give
		you more responsiveness if your delivery mode is set to
		queue-only.
	Allow "fileopen" timeout (default: 60 seconds) for opening
		:include: and .forward files.
	Add "-k", "-v", and "-z" flags to map definitions; these set the
		key field name, the value field name, and the field
		delimiter.  The field delimiter can be a single character
		or the sequence "\t" or "\n" for tab or newline.
		These are for use by NIS+ and similar access methods.
	Change maps to always strip quotes before lookups; the -q flag
		turns off this behavior.  Suggested by Motonori Nakamura.
	Add "nisplus" map class.  Takes -k and -v flags to choose the
		key and value field names respectively.  Code donated by
		Sun Microsystems.
	Add "hesiod" map class.  The "file name" is used as the
		"HesiodNameType" parameter to hes_resolve(3).  Returns the
		first value found for the match.  Code donated by Scott
		Hutton of Indiana University.
	Add "netinfo" (NeXT NetInfo) map class.  Maps can have a -k flag to
		specify the name of the property that is searched as the
		key and a -v flag to specify the name of the property that
		is returned as the value (defaults to "members").  The
		default map is "/aliases".  Some code based on code
		contributed by Robert La Ferla of Hot Software.
	Add "text" map class.  This does slow, linear searches through
		text files.  The -z flag specifies a column delimiter
		(defaults to any sequence of white space), the -k flag
		sets the key column number, and the -v flag sets the
		value column number.  Lines beginning with `#' are treated
		as comments.
	Add "program" map class to execute arbitrary programs.  The search
		key is presented as the last argument; the output is one
		line read from the programs standard output.  Exit statuses
		are from sysexits.h.
	Add "sequence" map class -- searches maps in sequence until it
		finds a match.  For example, the declarations:
		    Kmap1 ...
		    Kmap2 ...
		    Kmapseq sequence map1 map2
		defines a map "mapseq" that first searches map1; if the
		value is found it is returned immediately, otherwise
		map2 is searched and the value returned.
	Add "switch" map class.  This is much like "sequence" except that
		the ordering is fetched from an external file, usually
		the system service switch.  The parameter is the name of
		the service to switch on, and the maps that it will use
		are the name of the switch map followed by ".service_type".
		For example, if the declaration of the map is
		    Ksample switch hosts
		and the system service switch specifies that hosts are
		looked up using dns and nis in that order, then this is
		equivalent to
		    Ksample sequence sample.dns sample.nis
		The subordinate maps (sample.*) must already be defined.
	Add "user" map class -- looks up users using getpwnam.  Takes a
		"-v field" flag on the definition that tells what passwd
		entry to return -- legal values are name, passwd, uid, gid,
		gecos, dir, and shell.  Generally expected to be used with
		the -m (matchonly) flag.
	Add "bestmx" map class -- returns the best MX value for the host
		listed as the value.  If there are several "best" MX records
		for this host, one will be chosen at random.
	Add "userdb" map class -- looks up entries in the user database.
		The "file name" is actually the tag that will be used,
		typically "mailname".  If there are multiple entries
		matching the name, the one chosen is undefined.
	Add multiple queue timeouts (both return and warning).  These are
		set by the Precedence: or Priority: header fields to one of
		three values.  If a Priority: is set and has value "normal",
		"urgent", or "non-urgent" the corresponding timeouts are
		used.  If no priority is set, the Precedence: is consulted;
		if negative, non-urgent timeouts are used; if greater than
		zero, urgent timeouts are used.  Otherwise, normal timeouts
		are used.  The timeouts are set by setting the six timeouts
		queue{warn,return}.{urgent,normal,non-urgent}.
	Fix problem when a mail address is resolved to a $#error mailer
		with a temporary failure indication; it works in SMTP,
		but when delivering locally the mail is silently discarded.
		This patch, from Kyle Jones of UUNET, bounces it instead
		of queueing it (queueing is very hard).
	When using /etc/hosts or NIS-style lookups, don't assume that
		the first name in the list is the best one -- instead,
		search for the first one with a dot.  For example, if
		an /etc/hosts entry reads
		    128.32.149.68	mammoth mammoth.CS.Berkeley.EDU
		this change will use the second name as the canonical
		machine name instead of the initial, unqualified name.
	Change dequote map to replace spaces in quoted text with a value
		indicated by the -s flag on the dequote map definition.
		For example, ``Mdequote dequote -s_'' will change
		"Foo Bar" into an unquoted Foo_Bar instead of leaving it
		quoted (because of the space character).  Suggested by Dan
		Oscarsson for use in X.400 addresses.
	Implement long macro names as ${name}; long class names can
		be similarly referenced as $={name} and $~{name}.
		Definitions are (e.g.) ``D{name}value''.  Names that have
		a leading lower case letter or punctuation characters are
		reserved for internal use by sendmail; i.e., config files
		should use names that begin with a capital letter.  Based
		on code contributed by Dan Oscarsson.
	Fix core dump if getgrgid returns a null group list (as opposed
		to an empty group list, that is, a pointer to a list
		with no members).  Fix from Andrew Chang of Sun Microsystems.
	Fix possible core dump if malloc fails -- if the malloc in xalloc
		failed, it called syserr which called newstr which called
		xalloc....  The newstr is now avoided for "panic" messages.
		Reported by Stuart Kemp of James Cook University.
	Improve connection cache timeouts; previously, they were not even
		checked if you were delivering to anything other than an
		IPC-connected host, so a series of (say) local mail
		deliveries could cause cached connections to be open
		much longer than the specified timeout.
	If an incoming message exceeds the maximum message size, stop
		writing the incoming bytes to the queue data file, since
		this can fill your mqueue partition -- this is a possible
		denial-of-service attack.
	Don't reject all numeric local user names unless HESIOD is
		defined.  It turns out that Posix allows all-numeric
		user names.  Fix from Tony Sanders of BSDI.
	Add service switch support.  If the local OS has a service
		switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf
		on DEC systems) that will be used; otherwise, it falls back
		to using a local mechanism based on the ServiceSwitchFile
		option (default: /etc/service.switch).  For example, if the
		service switch lists "files" and "nis" for the aliases
		service, that will be the default lookup order.  the "files"
		("local" on DEC) service type expands to any alias files
		you listed in the configuration file, even if they aren't
		actually file lookups.
	Option I (NameServerOptions) no longer sets the "UseNameServer"
		variable which tells whether or not DNS should be considered
		canonical.  This is now determined based on whether or not
		"dns" is in the service list for "hosts".
	Add preliminary support for the ESMTP "DSN" extension (Delivery
		Status Notifications).  DSN notifications override
		Return-Receipt-To: headers, which are bogus anyhow --
		support for them has been removed.
	Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer
		definitions to define the types used in DSN returns for
		MTA names, addresses, and diagnostics respectively.
	Extend heuristic to force running in ESMTP mode to look for the
		five-character string "ESMTP" anywhere in the 220 greeting
		message (not just the second line).  This is to provide
		better compatibility with other ESMTP servers.
	Print sequence number of job when running the queue so you can
		easily see how much progress you have made.  Suggested
		by Peter Wemm of DIALix.
	Map newlines to spaces in logged message-ids; some versions of
		syslog truncate the rest of the line after newlines.
		Suggested by Fletcher Mattox of U. Texas.
	Move up forking for job runs so that if a message is split into
		multiple envelopes you don't get "fork storms" -- this
		also improves the connection cache utilization.
	Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for
		the purposes of refusing to send error returns.  Suggested
		by Motonori Nakamura of Ritsumeikan University.
	Relax rules on when a file can be written when referenced from
		the aliases file: use the default uid/gid instead of the
		real uid/gid.  This allows you to create a file owned by
		and writable only by the default uid/gid that will work
		all the time (without having the set-user-ID bit set).  Change
		suggested by Shau-Ping Lo and Andrew Cheng of Sun
		Microsystems.
	Add "DialDelay" option (no short name) to provide an "extra"
		delay for dial on demand systems.  If this is non-zero
		and a connect fails, sendmail will wait this long and
		then try again.  If it takes longer than the kernel
		timeout interval to establish the connection, this
		option can give the network software time to establish
		the link.  The default units are seconds.
	Move logging of sender information to be as early as possible;
		previously, it could be delayed a while for SMTP mail
		sent to aliases.  Suggested by Brad Knowles of the
		Defense Information Systems Agency.
	Call res_init() before setting RES_DEBUG; this is required by
		BIND 4.9.3, or so I'm told.  From Douglas Anderson of
		the National Computer Security Center.
	Add xdelay= field in logs -- this is a transaction delay, telling
		you how long it took to deliver to this address on the
		last try.  It is intended to be used for sorting mailing
		lists to favor "quick" addresses.  Provided for use by
		the mailprio scripts (see below).
	If a map cannot be opened, and that map is non-optional, and
		an address requires that map for resolution, queue the
		map instead of bouncing it.  This involves creating a
		pseudo-class of maps called "bogus-map" -- if a required
		map cannot be opened, the class is changed to bogus-map;
		all queries against bogus-map return "tempfail".  The
		bogus-map class is not directly accessible.  A sample
		implementation was donated by Jem Taylor of Glasgow
		University Computing Service.
	Fix a possible core dump when mailing to a program that talks
		SMTP on its standard input.  Fix from Keith Moore of
		the University of Kentucky.
	Make it possible to resolve filenames to $#local $: @ /filename;
		previously, the "@" would cause it to not be recognized
		as a file.  Problem noted by Brian Hill of U.C. Davis.
	Accept a -1 signal to re-exec the daemon.  This only works if
		argv[0] is a full path to sendmail.
	Fix bug in "addr=..." field in O option on little-endian machines
		-- the network number wasn't being converted to network
		byte order.  Patch from Kurt Lidl of Pix Technologies
		Corporation.
	Pre-initialize the resolver early on; this is to avoid a bug with
		BIND 4.9.3 that can cause the _res.retry field to get
		reset to zero, causing all name server lookups to time
		out.  Fix from Matt Day of Artisoft.
	Restore T line (trusted users) in config file -- but instead of
		locking out the -f flag, they just tell whether or not
		an X-Authentication-Warning: will be added.  This really
		just creates new entries in class 't', so "Ft/file/name"
		can be used to read trusted user names from a file.
		Trusted users are also allowed to execute programs even
		if they have a shell that isn't in /etc/shells.
	Improve NEWDB alias file rebuilding so it will create them
		properly if they do not already exist.  This had been
		a MAYBENEXTRELEASE feature in 8.6.9.
	Check for @:@ entry in NIS maps before starting up to avoid
		(but not prevent, sigh) race conditions.  This ought to
		be handled properly in ypserv, but isn't.  Suggested by
		Michael Beirne of Motorola.
	Refuse connections if there isn't enough space on the filesystem
		holding the queue.  Contributed by Robert Dana of Wolf
		Communications.
	Skip checking for directory permissions in the path to a file
		when checking for file permissions iff setreuid()
		succeeded -- it is unnecessary in that case.  This avoids
		significant performance problems when looking for .forward
		files.  Based on a suggestion by Win Bent of USC.
	Allow symbolic ruleset names.  Syntax can be "Sname" to get an
		arbitrary ruleset number assigned or "Sname = integer"
		to assign a specific ruleset number.  Reference is
		$>name_or_number.  Names can be composed of alphas, digits,
		underscore, or hyphen (first character must be non-numeric).
	Allow -o flag on AliasFile lines to make the alias file optional.
		From Bryan Costales of ICSI.
	Add NoRecipientAction option to handle the case where there is
		no legal recipient header in the message.  It can take
		on values:
		  None			Leave the message as is.  The
					message will be passed on even
					though it is in technically
					illegal syntax.
		  Add-To		Add a To: header with any
					recipients that it can find from
					the envelope.  This risks exposing
					Bcc: recipients.
		  Add-Apparently-To	Add an Apparently-To: header.  This
					has almost no redeeming social value,
					and is provided only for back
					compatibility.
		  Add-To-Undisclosed	Add a header reading
					To: undisclosed-recipients:;
					which will have the effect of
					making the message legal without
					exposing Bcc: recipients.
		  Add-Bcc		To add an empty Bcc: header.
					There is a chance that mailers down
					the line will delete this header,
					which could cause exposure of Bcc:
					recipients.
		The default is NoRecipientAction=None.
	Truncate (rather than delete) Bcc: lines in the header.  This
		should prevent later sendmails (at least, those that don't
		themselves delete Bcc:) from considering this message to
		be non-conforming -- although it does imply that non-blind
		recipients can see that a Bcc: was sent, albeit not to whom.
	Add SafeFileEnvironment option.  If declared, files named as delivery
		targets must be regular files in addition to the regular
		checks.  Also, if the option is non-null then it is used as
		the name of a directory that is used as a chroot(2)
		environment for the delivery; the file names listed in an
		alias or forward should include the name of this root.
		For example, if you run with
			O SafeFileEnvironment=/arch
		then aliases should reference "/arch/rest/of/path".  If a
		value is given, sendmail also won't try to save to
		/usr/tmp/dead.letter (instead it just leaves the job in the
		queue as Qfxxxxxx).  Inspired by *Hobbit*'s sendmail patch kit.
	Support -A flag for alias files; this will comma concatenate like
		entries.  For example, given the aliases:
			list: member1
			list: member2
		and an alias file declared as:
			OAhash:-A /etc/aliases
		the final alias inserted will be "list: member1,member2";
		without -A you will get an error on the second and subsequent
		alias for "list".  Contributed by Bryan Costales of ICSI.
	Line-buffer transcript file.  Suggested by Liudvikas Bukys.
	Fix a problem that could cause very long addresses to core dump in
		some special circumstances.  Problem pointed out by Allan
		Johannesen.
	(Internal change.)  Change interface to expand() (macro expansion)
		to be simpler and more consistent.
	Delete check for funny qf file names.  This didn't really give
		any extra security and caused some people some problems.
		(If you -really- want this, define PICKY_QF_NAME_CHECK
		at compile time.)  Suggested by Kyle Jones of UUNET.
	(Internal change.)  Change EF_NORETURN to EF_NO_BODY_RETN and
		merge with DSN code; this is simpler and more consistent.
		This may affect some people who have written their own
		checkcompat() routine.
	(Internal change.)  Eliminate `D' line in qf file.  The df file
		is now assumed to be the same name as the qf file (with
		the `q' changed to a `d', of course).
	Avoid forking for delivery if all recipient mailers are marked as
		"expensive" -- this can be a major cost on some systems.
		Essentially, this forces sendmail into "queue only" mode
		if all it is going to do is queue anyway.
	Avoid sending a null message in some rather unusual circumstances
		(specifically, the RCPT command returns a temporary
		failure but the connection is lost before the DATA
		command).  Fix from Scott Hammond of Secure Computing
		Corporation.
	Change makesendmail to use a somewhat more rational naming scheme:
		Makefiles and obj directories are named $os.$rel.$arch,
		where $os is the operating system (e.g., SunOS), $rel is
		the release number (e.g., 5.3), and $arch is the machine
		architecture (e.g., sun4).  Any of these can be omitted,
		and anything after the first dot in a release number can
		be replaced with "x" (e.g., SunOS.4.x.sun4).  The previous
		version used $os.$arch.$rel and was rather less general.
	Change makesendmail to do a "make depend" in the target directory
		when it is being created.  This involves adding an empty
		"depend:" entry in most Makefiles.
	Ignore IDENT return value if the OSTYPE field returns "OTHER",
		as indicated by RFC 1413.  Pointed out by Kari Hurtta
		of the Finnish Meteorological Institute.
	Fix problem that could cause multiple responses to DATA command
		on header syntax errors (e.g., lines beginning with colons).
		Problem noted by Jens Thomassen of the University of Oslo.
	Don't let null bytes in headers cause truncation of the rest of
		the header.
	Log Authentication-Warning:s.  Suggested by Motonori Nakamura.
	Increase timeouts on message data puts to allow time for receivers
		to canonify addresses in headers on the fly.  This is still
		a rather ugly heuristic.  From Motonori Nakamura.
	Add "HasWildcardMX" suboption to ResolverOptions; if set, MX
		records are not used when canonifying names, and when MX
		lookups are done for addressing they must be fully
		qualified.  This is useful if you have a wildcard MX record,
		although it may cause other problems.  In general, don't use
		wildcard MX records.  Patch from Motonori Nakamura.
	Eliminate default two-line SMTP greeting message.  Instead of
		adding an extra "ESMTP spoken here" line, the word "ESMTP"
		is added between the first and second word of the first
		line of the greeting message (i.e., immediately after the
		host name).  This eliminates the need for the BROKEN_SMTP_PEERS
		compile flag.  Old sendmails won't see the ESMTP, but that's
		acceptable because SIZE was the only useful extension that
		old sendmails understand.
	Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1
		invoked state dumps.  From Masaharu Onishi.
	Allow on-line comments in .forward and :include: files; they are
		introduced by the string "<LWSP>#@#<LWSP>", where <LWSP>
		is a space or a tab.  This is intended for native
		representation of non-ASCII sets such as Japanese, where
		existing encodings would be unreadable or would lose
		data -- for example,
		 <motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori
					(romanized/less information)
		 <motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?=
					      =?ISO-2022-JP?B?GyRCQUdFNRsoQg==?=
					(with MIME encoding, not human readable)
		 <motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B
					(native encoding with ISO-2022-JP)
		The last form is human readable in the Japanese environment.
		Based on a fix from (surprise!) Motonori Nakamura.
	Don't make SMTP error returns on MAIL FROM: line be "sticky" for all
		messages to that host; these are most frequently associated
		with addresses rather than the host, with the exception of
		421 (service shutting down).  The effect was to cause queues
		to sometimes take an excessive time to flush.  Reported by
		Robert Sargent of Southern Geographics Technologies and
		Eric Prestemon of American University.
	Add Nice=N mailer option to set the niceness at which a mailer will
		run.  This is actually a relative niceness (that is, an
		increment on the background value).
	Log queue runs that are skipped due to high loads.  They are logged
		at LOG_INFO priority iff the log level is > 8.  Contributed
		by Bruce Nagel of Data General.
	Allow the error mailer to accept a DSN-style error status code
		instead of an sysexits status code in the host part.
		Anything with a dot will be interpreted as a DSN-style code.
	Add new mailer flag: F=3 will tell translations to Quoted-Printable
		to encode characters that might be munged by an EBCDIC system
		in addition to the set required by RFC 1521.  The additional
		characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~.
		(Think of "IBM 360" as the mnemonic for this flag.)
	Change check for mailing to files to look for a pathname of [FILE]
		rather than looking for the mailer named *file*.  The mapping
		of leading slashes still goes to the *file* mailer.  This
		allows you to implement the *file* mailer as a separate
		program, for example, to insert a Content-Length: header
		or do special security policy.  However, note that the usual
		initial checking for the file permissions is still done, and
		the program in question needs to be very careful about how
		it does the file write to avoid security problems.
	Be able to read ~root/.forward even if the path isn't accessible to
		regular users.  This is disrecommended because sendmail
		sometimes does not run as root (e.g., when an unsafe option
		is specified on the command line), but should otherwise be
		safe because .forward files must be owned by the user for
		whom mail is being forwarded, and cannot be a symbolic link.
		Suggested by Forrest Aldrich of Wang Laboratories.
	Add new "HostsFile" option that is the pathname to the /etc/hosts
		file.  This is used for canonifying hostnames when the
		service type is "files".
	Implement programs on F (read class from file) line.  The syntax is
		Fc|/path/to/program to read the output from the program
		into class "c".
	Probe the network interfaces to find alternate names for this
		host.  Requires the SIOCGIFCONF ioctl call.  Code
		contributed by SunSoft.
	Add "E" configuration line to set or propagate environment
		variables into children.  "E<envar>" will propagate
		the named variable from the environment when sendmail
		was invoked into any children it calls; "E<envar>=<value>"
		sets the named variable to the indicated value.  Any
		variables not explicitly named will not be in the child
		environment.  However, sendmail still forces an
		"AGENT=sendmail" environment variable, in part to enforce
		at least one environment variable, since many programs and
		libraries die horribly if this is not guaranteed.
	Change heuristic for rebuilding both NEWDB and NDBM versions of
		alias databases -- new algorithm looks for the substring
		"/yp/" in the file name.  This is more portable and involves
		less overhead.  Suggested by Motonori Nakamura.
	Dynamically allocate the queue work list so that you don't lose
		jobs in large queue runs.  The old QUEUESIZE compile parameter
		is replaced by QUEUESEGSIZE (the unit of allocation, which
		should not need to be changed) and the MaxQueueRunSize option,
		which is the absolute maximum number of jobs that will ever
		be handled in a single queue run.  Based on code contributed
		by Brian Coan of the Institute for Global Communications.
	Log message when a message is dropped because it exceeds the maximum
		message size.  Suggested by Leo Bicknell of Virginia Tech.
	Allow trusted users (those on a T line or in $=t) to use -bs without
		an X-Authentication-Warning: added.  Suggested by Mark Thomas
		of Mark G. Thomas Consulting.
	Announce state of compile flags on -d0.1 (-d0.10 throws in the
		OS-dependent defines).  The old semantic of -d0.1 to not
		run the daemon in background has been moved to -d99.100,
		and the old 52.5 flag (to avoid disconnect() from closing
		all output files) has been moved to 52.100.  This makes
		things more consistent (flags below .100 don't change
		semantics) and separates out the backgrounding so that
		it doesn't happen automatically on other unrelated debugging
		flags.
	If -t is used but no addresses are found in the header, give an
		error message rather than just doing nothing.  Fix from
		Motonori Nakamura.
	On systems (like SunOS) where the effective gid is not necessarily
		included in the group list returned by getgroups(), the
		`restrictmailq' option could sometimes cause an authorized
		user to not be able to use `mailq'.  Fix from Charles Hannum
		of MIT.
	Allow symbolic service names for [IPC] mailers.  Suggested by
		Gerry Magennis of Logica International.
	Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs
		when running DNS.  For example, if the name FTP.Foo.ORG is
		a CNAME for Cruft.Foo.ORG, then when sitting on a machine in
		the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG"
		if this option is not set, or "FTP.Foo.ORG" if it is set.
		This is technically illegal under RFC 822 and 1123, but the
		IETF is moving toward legalizing it.  Note that turning on
		this option is not sufficient to guarantee that a downstream
		neighbor won't rewrite the address for you.
	Add "-m" flag to makesendmail script -- this tells you what object
		directory and Makefile it will use, but doesn't actually do
		the make.
	Do some additional checking on the contents of the qf file to try
		to detect attacks against the qf file.  In particular,
		abort on any line beginning "From ", and add an "end of
		file" line -- any data after that line is prohibited.
	Always use /etc/sendmail.cf, regardless of the arbitrary vendor
		choices.  This can be overridden in the Makefile by using
		either -DUSE_VENDOR_CF_PATH to get the vendor location
		(to the extent that we know it) or by defining
		_PATH_SENDMAILCF (which is a "hard override").  This allows
		sendmail 8 to have more consistent installation instructions.
	Allow macros on `K' line in config file.  Suggested by Andrew Chang
		of Sun Microsystems.
	Improved symbol table hash function from Eric Wassenaar.  This one
		is at least 50% faster.
	Fix problem that didn't notice that timeout on file open was a
		transient error.  Fix from Larry Parmelee of Cornell
		University.
	Allow comments (lines beginning with a `#') in files read for
		classes.  Suggested by Motonori Nakamura.
	Make SIGINT (usually ^C) in test mode return to the prompt instead
		of dropping out entirely.  This makes testing some of the
		name server lookups easier to deal with when there are
		hung servers.  From Motonori Nakamura.
	Add new ${opMode} macro that is set to the current operation mode
		(e.g., `s' for -bs, `t' for -bt, etc.).  Suggested by
		Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>.
	Add new delivery mode (Odd) that defers all map lookups to queue runs.
		Kind of like queue-only mode (Odq) except it tries to avoid
		any external service requests; for dial-on-demand hosts that
		want to minimize DNS lookups when mail is being queued.  For
		this to work you will also have to make sure that gethostbyname
		of your local host name does not do a DNS lookup.
	Improved handling of "out of space" conditions from John Myers of
		Carnegie Mellon.
	Improved security for mailing to files on systems that have fchmod(2)
		support.
	Improve "cannot send message for N days" message -- now says "could
		not send for past N days".  Suggested by Tom Moore of AT&T
		Global Information Solutions.
	Less misleading Subject: line on messages sent to postmaster only.
		From Motonori Nakamura.
	Avoid duplicate error messages on bad command line flags.  From
		Motonori Nakamura.
	Better error message for case where ruleset 0 falls off the end
		or otherwise does not resolve to a canonical triple.
	Fix a problem that could cause multiple bounce messages if a bad
		address was sent along with a good address to an SMTP
		site where that SMTP site returned a 4yz code in response
		to the final dot of the data.  Problem reported by David
		James of British Telecom.
	Add "volatile" declarations so that gcc -O2 will work.  Patches
		from Alexander Dupuy of System Management ARTS.
	Delete duplicates in MX lists -- believe it or not, there are sites
		that list the same host twice in an MX list.  This deletion
		only works on adjacent preferences, so an MX list that
		had A=5, B=10, A=15 would leave both As, but one that had
		A=5, A=10, B=15 would reduce to A, B.  This is intentional,
		just in case there is something weird I haven't thought of.
		Suggested by Barry Shein of Software Tool & Die.
	SECURITY: .forward files cannot be symbolic links.  If they are,
		a bad guy can read your private files.
	PORTABILITY FIXES:
		Solaris 2 from Rob McMahon <cudcv@csv.warwick.ac.uk>.
		System V Release 4 from Motonori Nakamura of Ritsumeikan
			University.  This expands the disk size
			checking to include all (?) SVR4 configurations.
		System V Release 4 from Kimmo Suominen -- initgroups(3)
			and setrlimit(2) are both available.
		System V Release 4 from sob@sculley.ffg.com -- some versions
			apparently "have EX_OK defined in other headerfiles."
		Linux Makefile typo.
		Linux getusershell(3) is broken in Slackware 2.0 --
			from Andrew Pam of Xanadu Australia.
		More Linux tweaking from John Kennedy of California State
			University, Chico.
		Cray changes from Eric Wassenaar:  ``On Cray, shorts,
			ints, and longs are all 64 bits, and all structs
			are multiples of 64 bits.  This means that the
			sizeof operator returns only multiples of 8.
			This requires adaptation of code that really
			deals with 32 bit or 16 bit fields, such as IP
			addresses or nameserver fields.''
		DG/UX 5.4.3 from Mark T. Robinson <mtr@ornl.gov>.  To
			get the old behavior, use -DDGUX_5_4_2.
		DG/UX hack: add _FORCE_MAIL_LOCAL_=yes environment
			variable to fix bogus /bin/mail behavior.
		Tandem NonStop-UX from Rick McCarty <mccarty@mpd.tandem.com>.
			This also cleans up some System V Release 4 compile
			problems.
		Solaris 2: sendmail.cw file should be in /etc/mail to
			match all the other configuration files.  Fix
			from Glenn Barry of Emory University.
		Solaris 2.3: compile problem in conf.c.  Fix from Alain
			Nissen of the University of Liege, Belgium.
		Ultrix: freespace calculation was incorrect.  Fix from
			Takashi Kizu of Osaka University.
		SVR4: running in background gets a SIGTTOU because the
			emulation code doesn't realize that "getpeername"
			doesn't require reading the file.  Fix from Peter
			Wemm of DIALix.
		Solaris 2.3: due to an apparent bug in the socket emulation
			library, sockets can get into a "wedged" state where
			they just return EPROTO; closing and re-opening the
			socket clears the problem.  Fix from Bob Manson
			of Ohio State University.
		Hitachi 3050R & 3050RX running HI-UX/WE2: portability
			fixes from Akihiro Hashimoto ("Hash") of Chiba
			University.
		AIX changes to allow setproctitle to work from Rainer Schöpf
			of Zentrum für Datenverarbeitung der Universität
			Mainz.
		AIX changes for load average from Ed Ravin of NASA/Goddard.
		SCO Unix from Chip Rosenthal of Unicom (code was using the
			wrong statfs call).
		ANSI C fixes from Adam Glass (NetBSD project).
		Stardent Titan/ANSI C fixes from Kate Hedstrom of Rutgers
			University.
		DG-UX fixes from Bruce Nagel of Data General.
		IRIX64 updates from Mark Levinson of the University of
			Rochester Medical Center.
		Altos System V (``the first UNIX/XENIX merge the Altos
			did for their Series 1000 & Series 2000 line;
			their merged code was licensed back to AT&T and
			Microsoft and became System V release 3.2'') from
			Tim Rice <timr@crl.com>.
		OSF/1 running on Intel Paragon from Jeff A. Earickson
			<jeff@ssd.intel.com> of Intel Scalable Systems
			Division.
		Amdahl UTS System V 2.1.5 (SVr3-based) from Janet Jackson

		ISC UNIX from J. J. Bailey.
		HP-UX 9.xx on the 8xx series machines from Remy Giraud
			of Meteo France.
		HP-UX configuration from Tom Lane <tgl@sss.pgh.pa.us>.
		IRIX 5.2 and 5.3 from Kari E. Hurtta.
		FreeBSD 2.0 from Mike Hickey of Federal Data Corporation.

		NeXT 2.1 from Bryan Costales.
		AUX patch thanks to Mike Erwin of Apple Computer.
		HP-UX 10.0 from John Beck of Hewlett-Packard.
		Ultrix: allow -DBROKEN_RES_SEARCH=0 if you are using a
			non-DEC resolver.  Suggested by Allan Johannesen.
		UnixWare 2.0 fixes from Petr Lampa of the Technical
			University of Brno (Czech Republic).
		KSR OS 1.2.2 support from Todd Miller of the University
			of Colorado.
		UX4800 support from Kazuhisa Shimizu of NEC.
	MAKEMAP: allow -d flag to allow insertion of duplicate aliases
		in type ``btree'' maps.  The semantics of this are undefined
		for regular maps, but it can be useful for the user database.
	MAKEMAP: lock database file while rebuilding to avoid sendmail
		lookups while the rebuild is going on.  There is a race
		condition between the open(... O_TRUNC ...) and the lock
		on the file, but it should be quite small.
	SMRSH: sendmail restricted shell added to the release.  This can
		be used as an alternative to /bin/sh for the "prog" mailer,
		giving the local administrator more control over what
		programs can be run from sendmail.
	MAIL.LOCAL: add this local mailer to the tape.  It is not really
		part of the release proper, and isn't fully supported; in
		particular, it does not run on System V based systems and
		never will.
	CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon
		to allow rmail to compile on systems that don't have
		function prototypes and systems that don't have snprintf.
	CONTRIB: add the "mailprio" scripts that will help you sort mailing
		lists by transaction delay times so that addresses that
		respond quickly get sent first.  This is to prevent very
		sluggish servers from delaying other peoples' mail.
		Contributed by Tony Sanders of BSDI.
	CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders
		of BSDI.  This has a lot of comments to help people out.
	CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead,
		put this on the m4 command line.  On GNU m4 (which
		supports the __file__ primitive) you can run m4 in an
		arbitrary directory -- use either:
			m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf
		or
			m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf
		On other versions of m4 that don't support __file__, you
		can use:
			m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ...
		(Note the trailing slash on the _CF_DIR_ definition.)
		Old versions of m4 will default to _CF_DIR_=.. for back
		compatibility.
	CONFIG: fix mail from <> so it will properly convert to
		MAILER-DAEMON on local addresses.
	CONFIG: fix code that was supposed to catch colons in host
		names.  Problem noted by John Gardiner Myers of CMU.
	CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration.
		From Paul Riddle of the University of Maryland, Baltimore
		County.
	CONFIG: Catch and reject "." as a host address.
	CONFIG: Generalize domaintable to look up all domains, not
		just unqualified ones.
	CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it
		was never used and didn't work anyway.
	CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer
		and d on all mailers in the UUCP class.
	CONFIG: Allow "user+detail" to be aliased specially: it will first
		look for an alias for "user+detail", then for "user+*", and
		finally for "user".  This is intended for forwarding mail
		for system aliases such as root and postmaster to a
		centralized hub.
	CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above).
	CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set.
		The F=8 flag is also set on the "relay" mailer, since
		this is expected to be another sendmail.
	CONFIG: avoid qualifying all UUCP addresses sent via SMTP with
		the name of the UUCP_RELAY -- in some cases, this is the
		wrong value (e.g., when we have local UUCP connections),
		and this can create unreplyable addresses.  From Chip
		Rosenthal of Unicom.
	CONFIG: add confRECEIVED_HEADER to change the format of the
		Received: header inserted into all messages.  Suggested by
		Gary Mills of the University of Manitoba.
	CONFIG: Make "notsticky" the default; use FEATURE(stickyhost)
		to get the old behavior.  I did this upon observing
		that almost everyone needed this feature, and that the
		concept I was trying to make happen didn't work with
		some user agents anyway.  FEATURE(notsticky) still works,
		but it is a no-op.
	CONFIG: Add LUSER_RELAY -- the host to which unrecognized user
		names are sent, rather than immediately diagnosing them
		as User Unknown.
	CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS,
		and RELAY_MAILER_ARGS to set the arguments for the
		indicated mailers.  All default to "IPC $h".  Patch from
		Larry Parmelee of Cornell University.
	CONFIG: pop mailer needs F=n flag to avoid "annoying side effects
		on the client side" and F=P to get an appropriate
		return-path.  From Kimmo Suominen.
	CONFIG: add FEATURE(local_procmail) to use the procmail program
		as the local mailer.  For addresses of the form "user+detail"
		the "detail" part is passed to procmail via the -a flag.
		Contributed by Kimmo Suominen.
	CONFIG: add MAILER(procmail) to add an interface to procmail for
		use from mailertables.  This lets you execute arbitrary
		procmail scripts.  Contributed by Kimmo Suominen.
	CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers.
	CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent.  From
		Paul Southworth of CICNet Systems Support.
	CONFIG: use -a$g as default to UUCP mailers, instead of -a$f.
		This causes the null return path to be rewritten as
		MAILER-DAEMON; otherwise UUCP gets horribly confused.
		From Michael Hohmuth of Technische Universitat Dresden.
	CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that
		list us as the best possible MX record to be treated as
		though they were local (essentially, assume that they
		are included in $=w).  This can cause additional DNS
		traffic, but is easier to administer if this fits your
		local model.  It does not work reliably if there are
		multiple hosts that share the best MX preference.
		Code contributed by John Oleynick of Rutgers.
	CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted
		SHell) instead of /bin/sh as the program used for delivery
		to programs.  If an argument is included, it is used as
		the path to smrsh; otherwise, /usr/local/etc/smrsh is
		assumed.
	CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the
		size of messages to the local and procmail mailers
		respectively.  Contributed by Brad Knowles of the Defense
		Information Systems Agency.
	CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments
		(just like text outside of angle brackets) in order to
		properly deal with ``group: addr1, ... addrN;'' syntax.
	CONFIG: Require OSTYPE macro (the defaults really don't apply to
		any real systems any more) and tweak the DOMAIN macro
		so that it is less likely that users will accidentally use
		the Berkeley defaults.  Also, create some generic files
		that really can be used in the real world.
	CONFIG: Add new configuration macros to set character sets for
		messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET,
		SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET.
	CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency.
		The old name will still be accepted for a while at least.
	CONFIG: Implement DECNET_RELAY as spec for host to which DECNET
		mail (.DECNET pseudo-domain or node::user) will be sent.
		As with all relays, it can be ``mailer:hostname''.  Suggested
		by Scott Hutton.
	CONFIG: Add MAILER(mail11) to get DECnet support.  Code contributed
		by Barb Dijker of Labyrinth Computer Services.
	CONFIG: change confCHECK_ALIASES to default to False -- it has poor
		performance for large alias files, and this confused many
		people.
	CONFIG: Add confCF_VERSION to append local information to the
		configuration version number displayed during SMTP startup.
	CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it
		would only work when locally addressed.  Fix from
		Edvard Tuinder of Cistron Internet Services.
	CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option
		"n" (CheckAliases) is set when rebuilding alias database.
		Based on code contributed by Claude Marinier.
	CONFIG: Allow mailertable to have values of the form
		``error:code message''.  The ``code'' is a status code
		derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE.
		Contributed by David James <dwj@agw.bt.co.uk>.
	CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of
		sender domains that will be replaced with the masquerade name.
		These domains will not be treated as local, but if mail passes
		through with sender addresses in those domains they will be
		replaced by the masquerade name.  These can also be specified
		in a file using MASQUERADE_DOMAIN_FILE(filename).
	CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope
		as well as the header.  Substantial improvements to this
		code were contributed by Per Hedeland.
	CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be
		accessed from a mailertable to do CCSO ph lookups.  Contributed
		by Kimmo Suominen.
	CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be
		used to define cyrus and cyrusbb mailers (for IMAP support).
		Contributed by John Gardiner Myers of Carnegie Mellon.
	CONFIG: add confUUCP_MAILER to select default mailer to use for
		UUCP addressing.  Suggested by Tom Moore of AT&T GIS.

8.6.13/8.6.12	1996/01/25
	SECURITY: In some cases it was still possible for an attacker to
		insert newlines into a queue file, thus allowing access to
		any user (except root).
	CONFIG: no changes -- it is not a bug that the configuration
		version number is unchanged.

8.6.12/8.6.12	1995/03/28
	Fix to IDENT code (it was getting the size of the reply buffer
		too small, so nothing was ever accepted).  Fix from several
		people, including Allan Johannesen, Shane Castle of the
		Boulder County Information Services, and Jeff Smith of
		Warwick University (all arrived within a few hours of
		each other!).
	Fix a problem that could cause large jobs to run out of
		file descriptors on systems that use vfork() rather
		than fork().

8.6.11/8.6.11	1995/03/08
	The ``possible attack'' message would be logged more often
		than necessary if you are using Pine as a user agent.
	The wrong host would be reported in the ``possible attack''
		message when attempted from IDENT.
	In some cases the syslog buffer could be overflowed when
		reporting the ``possible attack'' message.  This can
		cause denial of service attacks.  Truncate the message
		to 80 characters to prevent this problem.
	When reading the IDENT response a loop is needed around the
		read from the network to ensure that you don't get
		partial lines.
	Password entries without any shell listed (that is, a null
		shell) wouldn't match as "ok".  Problem noted by
		Rob McMahon.
	When running BIND 4.9.x a problem could occur because the
		_res.options field is initialized differently than it
		was historically -- this requires that sendmail call
		res_init before it tweaks any bits.
	Fix an incompatibility in openxscript() between the file open mode
		and the stdio mode passed to fdopen.  This caused UnixWare
		2.0 to have conniptions.  Fix from Martin Sohnius of
		Novell Labs Europe.
	Fix problem with static linking of local getopt routine when
		using GNU's ld command.  Fix from John Kennedy of
		Cal State Chico.
	It was possible to turn off privacy flags.  Problem noted by
		*Hobbit*.
	Be more paranoid about writing files.  Suggestions by *Hobbit*
		and Liudvikas Bukys.
	MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular)
		from Spider Boardman.
	CONFIG: No changes (version number only, to keep it in sync
		with the binaries).

8.6.10/8.6.10	1995/02/10
	SECURITY: Diagnose bogus values to some command line flags that
		could allow trash to get into headers and qf files.
	Validate the name of the user returned by the IDENT protocol.
		Some systems that really dislike IDENT send intentionally
		bogus information.  Problem pointed out by Michael Bushnell
		of the Free Software Foundation.  Has some security
		implications.
	Fix a problem causing error messages about DNS problems when
		the host name contained a percent sign to act oddly
		because it was passed as a printf-style format string.
		In some cases this could cause core dumps.
	Avoid possible buffer overrun in returntosender() if error
		message is quite long.  From Fletcher Mattox of the
		University of Texas.
	Fix a problem that would silently drop "too many hops" error
		messages if and only if you were sending to an alias.
		From Jon Giltner of the University of Colorado and
		Dan Harton of Oak Ridge National Laboratory.
	Fix a bug that caused core dumps on some systems if -d11.2 was
		set and e->e_message was null.  Fix from Bruce Nagel of
		Data General.
	Fix problem that can still cause df files to be left around
		after "hop count exceeded" messages.  Fix from Andrew
		Chang and Shau-Ping Lo of SunSoft.
	Fix a problem that can cause buffer overflows on very long
		user names (as might occur if you piped to a program
		with a lot of arguments).
	Avoid returning an error and re-queueing if the host signature
		is null; this can occur on addresses like ``user@.''.
		Problem noted by Wesley Craig and the University of
		Michigan.
	Avoid possible calls to malloc(0) if MCI caching is turned
		off.  Bug fix from Pierre David of the Laboratoire
		Parallelisme, Reseaux, Systemes et Modelisation (PRiSM),
		Universite de Versailles - St Quentin, and Jacky
		Thibault.
	Make a local copy of the line being sent via senttolist() -- in
		some cases, buffers could get trashed by map lookups
		causing it to do unexpected things.  This also simplifies
		some of the map code.
	CONFIG: No changes (version number only, to keep it in sync
		with the binaries).

8.6.9/8.6.9	1994/04/19
	Do all mail delivery completely disconnected from any terminal.
		This provides consistency with daemon delivery and
		may have some security implications.
	Make sure that malloc doesn't get called with zero size,
		since that fails on some systems.  Reported by Ed
		Hill of the University of Iowa.
	Fix multi-line values for $e (SMTP greeting message).  Reported
		by Mike O'Connor of Ford Motor Company.
	Avoid syserr if no NIS domain name is defined, but the map it
		is trying to open is optional.  From Win Bent of USC.
	Changes for picky compilers from Ed Gould of Digital Equipment.
	Hesiod support for UDB from Todd Miller of the University of
		Colorado.  Use "hesiod" as the service name in the U
		option.
	Fix a problem that failed to set the "authentic" host name (that
		is, the one derived from the socket info) if you called
		sendmail -bs from inetd.  Based on code contributed by
		Todd Miller (this problem was also reported by Guy Helmer
		of Dakota State University).  This also fixes a related
		problem reported by Liudvikas Bukys of the University of
		Rochester.
	Parameterize "nroff -h" in all the Makefiles so people with
		variant versions can use them easily.  Suggested by
		Peter Collinson of Hillside Systems.
	SMTP "MAIL" commands with multiple ESMTP parameters required two
		spaces between parameters instead of one.  Reported by
		Valdis Kletnieks of Virginia Tech.
	Reduce the number of system calls during message collection by
		using global timeouts around the collect() loop.  This
		code was contributed by Eric Wassenaar.
	If the initial hostname name gathering results in a name
		without a dot (usually caused by NIS misconfiguration)
		and BIND is compiled in, directly access DNS to get
		the canonical name.  This should make life easier for
		Solaris systems.  If it still can't be resolved, and
		if the name server is listed as "required", try again
		in 30 seconds.  If that also fails, exit immediately to
		avoid bogus "config error: mail loops back to myself"
		messages.
	Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error
		message to explain how much space was available and
		sound a bit less threatening.  Suggested by Stan Janet
		of the National Institute of Standards and Technology.
	If mail is delivered to an alias that has an owner, deliver any
		requested return-receipt immediately, and strip the
		Return-Receipt-To: header from the subsequent message.
		This prevents a certain class of denial of service
		attack, arguably gives more reasonable semantics, and
		moves things more towards what will probably become a
		network standard.  Suggested by Christopher Davis of
		Kapor Enterprises.
	Add a "noreceipts" privacy flag to turn off all return receipts
		without recompiling.
	Avoid printing ESMTP parameters as part of the error message
		if there are errors during parsing.  This change is
		purely cosmetic.
	Avoid sending out error messages during the collect phase of
		SMTP; there is an MVS mailer from UCLA that gets
		confused by this.  Of course, I think it's their bug....
	Check for the $j macro getting undefined, losing a dot, or getting
		lost from $=w in the daemon before accepting a connection;
		if it is, it dumps state, prints a LOG_ALERT message,
		and drops core for debugging.  This is an attempt to
		track down a bug that I thought was long since gone.
		If you see this, please forward the log fragment to
		sendmail@sendmail.ORG.
	Change OLD_NEWDB from a #ifdef to a #if so it can be turned off
		with -DOLD_NEWDB=0 on the command line.  From Christophe
		Wolfhugel.
	Instead of trying to truncate the listen queue for the server
		SMTP port when the load average is too high, just close
		the port completely and reopen it later as needed.
		This ensures that the other end gets a quick "connection
		refused" response, and that the connection can be
		recovered later.  In particular, some socket emulations
		seem to get confused if you tweak the listen queue
		size around and can never start listening to connections
		again.  The down side is that someone could start up
		another daemon process in the interim, so you could
		have multiple daemons all not listening to connections;
		this could in turn cause the sendmail.pid file to be
		incorrect.  A better approach might be to accept the
		connection and give a 421 code, but that could break
		other mailers in mysterious ways and have paging behavior
		implications.
	Fix a glitch in TCP-level debugging that caused flag 16.101 to
		set debugging on the wrong socket.  From Eric Wassenaar.
	When creating a df* temporary file, be sure you truncate any
		existing data in the file -- otherwise system crashes
		and the like could result in extra data being sent.
	DOC: Replace the CHANGES-R5-R8 readme file with a paper in the
		doc directory.  This includes some additional
		information.
	CONFIG: change UUCP rules to never add $U! or $k! on the front
		of recipient envelope addresses.  This should have been
		handled by the $&h trick, but broke if people were
		mixing domainized and UUCP addresses.  They should
		probably have converted all the way over to uucp-uudom
		instead of uucp-{new,old}, but the failure mode was to
		loop the mail, which was bad news.
	Portability fixes:
		Newer BSDI systems (several people).
		Older BSDI systems from Christophe Wolfhugel.
		Intergraph CLIX, from Paul Southworth of CICNet.
		UnixWare, from Evan Champion.
		NetBSD from Adam Glass.
		Solaris from Quentin Campbell of the University of
			Newcastle upon Tyne.
		IRIX from Dean Cookson and Bill Driscoll of Mitre
			Corporation.
		NCR 3000 from Kevin Darcy of Chrysler Financial Corporation.
		SunOS (it has setsid() and setvbuf() calls) from
			Jonathan Kamens of OpenVision Technologies.
		HP-UX from Tor Lillqvist.

8.6.8/8.6.6	1994/03/21
	SECURITY: it was possible to read any file as root using the
		E (error message) option.  Reported by Richard Jones;
		fixed by Michael Corrigan and Christophe Wolfhugel.

8.6.7/8.6.6	1994/03/14
	SECURITY: it was possible to get root access by using weird
		values to the -d flag.  Thanks to Alain Durand of
		INRIA for forwarding me the notice from the bugtraq
		list.

8.6.6/8.6.6	1994/03/13
	SECURITY: the ability to give files away on System V-based
		systems proved dangerous -- don't run as the owner
		of a :include: file on a system that allows giveaways.
		Unfortunately, this also applies to determining a
		valid shell.
	IMPORTANT: Previous versions weren't expiring old connections
		in the connection cache for a long time under some
		circumstances.  This could result in resource exhaustion,
		both at your end and at the other end.  This checks the
		connections for timeouts much more frequently.  From
		Doug Anderson of NCSC.
	Fix a glitch that snuck in that caused programs to be run as
		the sender instead of the recipient if the mail was
		from a local user to another local user.  From
		Motonori Nakamura of Kyoto University.
	Fix "wildcard" on /etc/shells matching -- instead of looking
		for "*", look for "/SENDMAIL/ANY/SHELL/".  From
		Bryan Costales of ICSI.
	Change the method used to declare the "statfs" availability;
		instead of HASSTATFS and/or HASUSTAT with a ton of
		tweaking in conf.c, there is a single #define called
		SFS_TYPE which takes on one of six values (SFS_NONE
		for no statfs availability, SFS_USTAT for the ustat(2)
		syscall, SFS_4ARGS for a four argument statfs(2) call,
		and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument
		statfs(2) call with the declarations in <sys/vfs.h>,
		<sys/mount.h>, or <sys/statfs.h> respectively).
	Fix glitch in NetInfo support that could return garbage if
		there was no "/locations/sendmail" property.  From
		David Meyer of the University of Virginia.
	Change HASFLOCK from defined/not-defined to a 0/1 definition
		to allow Linux to turn it off even though it is a
		BSD-like system.
	Allow setting of "ident" timeout to zero to turn off the ident
		protocol entirely.
	Make 7-bit stripping local to a connection (instead of to a
		mailer); this allows you to specify that SMTP is a
		7-bit channel, but revert to 8-bit should it advertise
		that it supports 8BITMIME.  You still have to specify
		mailer flag 7 to get this stripping at all.
	Improve makesendmail script so it handles more cases automatically.
	Tighten up restrictions on taking ownership of :include: files
		to avoid problems on systems that allow you to give away
		files.
	Fix a problem that made it impossible to rebuild the alias
		file if it was on a read-only file system.  From
		Harry Edmon of the University of Washington.
	Improve MX randomization function.  From John Gardiner Myers
		of CMU.
	Fix a minor glitch causing a bogus message to be printed (used
		%s instead of %d in a printf string for the line number)
		when a bad queue file was read.  From Harry Edmon.
	Allow $s to remain NULL on locally generated mail.  I'm not
		sure this is necessary, but a lot of people have complained
		about it, and there is a legitimate question as to whether
		"localhost" is legal as an 822-style domain.
	Fix a problem with very short line lengths (mailer L= flag) in
		headers.  This causes a leading space to be added onto
		continuation lines (including in the body!), and also
		tries to wrap headers containing addresses (From:, To:,
		etc) intelligently at the shorter line lengths.  Problem
		Reported by Lars-Johan Liman of SUNET Operations Center.
	Log the real user name when logging syserrs, since these can have
		security implications.  Suggested by several people.
	Fix address logging of cached connections -- it used to always
		log the numeric address as zero.  This is a somewhat
		bogus implementation in that it does an extra system
		call, but it should be an inexpensive one.  Fix from
		Motonori Nakamura.
	Tighten up handling of short syslog buffers even more -- there
		were cases where the outgoing relay= name was too long
		to share a line with delay= and mailer= logging.
	Limit the overhead on split envelopes to one open file descriptor
		per envelope -- previously the overhead was three
		descriptors.  This was in response to a problem reported
		by P{r (Pell) Emanuelsson.
	Fixes to better handle the case of unexpected connection closes;
		this redirects the output to the transcript so the info
		is not lost.  From Eric Wassenaar.
	Fix potential string overrun if you macro evaluate a string that
		has a naked $ at the end.  Problem noted by James Matheson
		<jmrm@eng.cam.ac.uk>.
	Make default error number on $#error messages 553 (``Requested
		action not taken: mailbox name not allowed'') instead of
		501 (``Syntax error in parameters or arguments'') to
		avoid bogus "protocol error" messages.
	Strip off any existing trailing dot on names during $[ ... $]
		lookup.  This prevents it from ending up with two dots
		on the end of dot terminated names.  From Wesley Craig
		of the University of Michigan and Bryan Costales of ICSI.
	Clean up file class reading so that the debugging information is
		more informative.  It hadn't been using setclass, so you
		didn't see the class items being added.
	Avoid core dump if you are running a version of sendmail where
		NIS is compiled in, and you specify an NIS map, but
		NIS is not running.  Fix from John Oleynick of
		Rutgers.
	Diagnose bizarre case where res_search returns a failure value,
		but sets h_errno to a success value.
	Make sure that "too many hops" messages are considered important
		enough to send an error to the Postmaster (that is, the
		address specified in the P option).  This fix should
		help problems that cause the df file to be left around
		sometimes -- unfortunately, I can't seem to reproduce
		the problem myself.
	Avoid core dump (null pointer reference) on EXPN command; this
		only occurred if your log level was set to 10 or higher
		and the target account was an alias or had a .forward file.
		Problem noted by Janne Himanka.
	Avoid "denial of service" attacks by someone who is flooding your
		SMTP port with bad commands by shutting the connection
		after 25 bad commands are issued.  From Kyle Jones of
		UUNET.
	Fix core dump on error messages with very long "to" buffers;
		fmtmsg overflows the message buffer.  Fixed by trimming
		the to address to 203 characters.  Problem reported by
		John Oleynick.
	Fix configuration for HASFLOCK -- there were some spots where
		a #ifndef was incorrectly #ifdef.  Pointed out by
		George Baltz of the University of Maryland.
	Fix a typo in savemail() that could cause the error message To:
		lists to be incorrect in some places.  From Motonori
		Nakamura.
	Fix a glitch that can cause duplicate error messages on split
		envelopes where an address on one of the lists has a
		name server failure.  Fix from Voradesh Yenbut of the
		University of Washington.
	Fix possible bogus pointer reference on ESMTP parameters that
		don't have an ``=value'' part.
	CNAME loops caused an error message to be generated, but also
		re-queued the message.  Changed to just re-queue the
		message (it's really hard to just bounce it because
		of the weird way the name server works in the presence
		of CNAME loops).  Problem noted by James M.R.Matheson
		of Cambridge University.
	Avoid giving ``warning: foo owned process doing -bs'' messages
		if they use ``MAIL FROM:<foo>'' where foo is their true
		user name.  Suggested by Andreas Stolcke of ICSI.
	Change the NAMED_BIND compile flag to be a 0/1 flag so you can
		override it easily in the Makefile -- that is, you can
		turn it off using -DNAMED_BIND=0.
	If a gethostbyname(...) of an address with a trailing dot fails,
		try it without the trailing dot.  This is because if
		you have a version of gethostbyname() that falls back
		to NIS or the /etc/hosts file it will fail to find
		perfectly reasonable names that just don't happen to
		be dot terminated in the hosts file.  You don't want to
		strip the dot first though because we're trying to ensure
		that country names that match one of your subdomains get
		a chance.
	PRALIASES: fix bogus output on non-null-terminated strings.
		From Bill Gianopoulos of Raytheon.
	CONFIG: Avoid rewriting anything that matches $w to be $j.
		This was in code intended to only catch the self-literal
		address (that is, [1.2.3.4], where 1.2.3.4 is your
		IP address), but the code was broken.  However, it will
		still do this if $M is defined; this is necessary to
		get client configurations to work (sigh).  Note that this
		means that $M overrides :mailname entries in the user
		database!  Problem noted by Paul Southworth.
	CONFIG: Fix definition of Solaris help file location.  From
		Steve Cliffe <steve@gorgon.cs.uow.edu.au>.
	CONFIG: Fix bug that broke news.group.USENET mappings.
	CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX,
		and USENET_MAILER_MAX to tweak the maximum message
		size for various mailers.
	CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0]
		instead of assuming that it is "inews" for consistency
		with other mailers.  From Michael Corrigan of UC San Diego.
	CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB,
		qualify the address in the SMTP envelope as user@{relay|hub}
		instead of user@$j.  From Bill Wisner of The Well.
	CONFIG: Fix route-addr syntax in nullrelay configuration set.
	CONFIG: Don't turn off case mapping of user names in the local
		mailer for IRIX.  This was different than most every other
		system.
	CONFIG: Avoid infinite loops on certainly list:; syntaxes in
		envelope.  Noted by Thierry Besancon
		<besancon@excalibur.ens.fr>.
	CONFIG: Don't include -z by default on uux line -- most systems
		don't want it set by default.  Pointed out by Philippe
		Michel of Thomson CSF.
	CONFIG: Fix some bugs with mailertables -- for example, if your
		host name was foo.bar.ray.com and you matched against
		".ray.com", the old implementation bound %1 to "bar"
		instead of "foo.bar".  Also, allow "." in the mailertable
		to match anything -- essentially, take over SMART_HOST.
		This also moves matching of explicit local host names
		before the mailertable so they don't have to be special
		cased in the mailertable data.  Reported by Bill
		Gianopoulos of Raytheon; the fix for the %1 binding
		problem was contributed by Nicholas Comanos of the
		University of Sydney.
	CONFIG: Don't include "root" in class $=L (users to deliver
		locally, even if a hub or relay exists) by default.
		This is because of the known bug where definition of
		both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore
		both and deliver into the local mailbox.
	CONFIG: Move up bitdomain and uudomain handling so that they
		are done before .UUCP class matching; uudomain was
		reported as ineffective before.  This also frees up
		diversion 8 for future use.  Problem reported by Kimmo
		Suominen.
	CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4])
		into host names.  As pointed out by Jonathan Kamens,
		these are often used because either the forward or reverse
		mapping is broken; this translation makes it broken again.
	DOC: Clarify $@ and $: in the Install & Op Guide.  From Kimmo
		Suominen.
	Portability fixes:
		Unicos from David L. Kensiski of Sterling Software.
		DomainOS from Don Lewis of Silicon Systems.
		GNU m4 1.0.3 from Karst Koymans of Utrecht University.
		Convex from Kimmo Suominen <kim@tac.nyc.ny.us>.

8.6.5/8.6.5	1994/01/13
	Security fix:  /.forward could be owned by anyone (the test
		to allow root to own any file was backwards).  From
		Bob Campbell at U.C. Berkeley.
	Security fix: group ids were not completely set when programs
		were invoked.  This caused programs to have group
		permissions they should not have had (usually group
		daemon instead of their own group).  In particular,
		Perl scripts would refuse to run.
	Security: check to make sure files that are written are not
		symbolic links (at least under some circumstances).
		Although this does not respond to a specific known
		attack, it's just a good idea.  Suggested by
		Christian Wettergren.
	Security fix: if a user had an NFS mounted home directory on
		a system with a restricted shell listed in their
		/etc/passwd entry, they could still execute any
		program by putting that in their .forward file.
		This fix prevents that by insisting that their shell
		appear in /etc/shells before allowing a .forward to
		execute a program or write a file.  You can disable
		this by putting "*" in /etc/shells.  It also won't
		permit world-writable :include: files to reference
		programs or files (there's no way to disable this).
		These behaviors are only one level deep -- for
		example, it is legal for a world-writable :include:
		file to reference an alias that writes a file, on
		the assumption that the alias file is well controlled.
	Security fix: root was not treated suspiciously enough when
		looking into subdirectories.  This would potentially
		allow a cracker to examine files that were publicly
		readable but in a non-publicly searchable directory.
	Fix a problem that causes an error on QUIT on a cached
		connection to create problems on the current job.
		These are typically unrelated, so errors occur in
		the wrong place.
	Reset CurrentLA in sendall() -- this makes sendmail queue
		runs more responsive to load average, and fixes a
		problem that ignored the load average in locally
		generated mail.  From Eric Wassenaar.
	Fix possible core dump on aliases with null LHS.  From
		John Orthoefer of BB&N.
	Revert to using flock() whenever possible -- there are just
		too many bugs in fcntl() locking, particularly over
		NFS, that cause sendmail to fail in perverse ways.
	Fix a bug that causes the connection cache to get confused
		when sending error messages.  This resulted in
		"unexpected close" messages.  It should fix itself
		on the following queue run.  Problem noted by
		Liudvikas Bukys of the University of Rochester.
	Include $k in $=k as documented in the Install & Op Guide.
		This seems odd, but it was documented....  From
		Michael Corrigan of UCSD.
	Fix problem that caused :include:s from alias files to be
		forced to be owned by root instead of daemon
		(actually DefUid).  From Tim Irvin.
	Diagnose unrecognized I option values -- from Mortin Forssen
		of the Chalmers University of Technology.
	Make "error" mailer work consistently when there is no error
		code associated with it -- previously it returned OK
		even though there was a real problem.  Now it assumes
		EX_UNAVAILABLE.
	Fix bug that caused the last header line of messages that had
		no body and which were terminated with EOF instead of
		"." to be discarded.  Problem noted by Liudvikas Bukys.
	Fix core dump on SMTP mail to programs that failed -- it tried
		to go to a "next MX host" when none existed, causing
		a core dump.  From der Mouse at McGill University.
	Change IDENTPROTO from a defined/not defined to a 0/1 switch;
		this makes it easier to turn it off (using
		-DIDENTPROTO=0 in the Makefile).  From der Mouse.
	Fix YP_MASTER_NAME store to use the unupdated result of
		gethostname() (instead of myhostname(), which tries
		to fully qualify the name) to be consistent with
		SunOS.  If your hostname is unqualified, this fixes
		transfers to slave servers.  Bug noted by Keith
		McMillan of Ameritech Services, Inc.
	Fix Ultrix problem: gethostbyname() can return a very large
		(> 500) h_length field, which causes the sockaddr
		to be trashed.  Use the size of the sockaddr instead.
		Fix from Bob Manson of Ohio State.
	Don't assume "-a." on host lookups if NAMED_BIND is not
		defined -- this confuses gethostbyname on hosts
		file lookups, which doesn't understand the trailing
		dot convention.
	Log SMTP server subprocesses that die with a signal instead
		of from a clean exit.
	If you don't have option "I" set, don't assume that a DNS
		"host unknown" message is authoritative -- it
		might still be found in /etc/hosts.
	Fix a problem that would cause Deferred: messages to be sent
		as the subject of an error message, even though the
		actual cause of a message was more severe than that.
		Problem noted by Chris Seabrook of OSSI.
	Fix race condition in DBM alias file locking.  From Kyle
		Jones of UUNET.
	Limit delivery syslog line length to avoid bugs in some
		versions of syslog(3).  This adds a new compile time
		variable SYSLOG_BUFSIZE.  From Jay Plett of Princeton
		University, which is in turn derived from IDA.
	Fix quotes inside of comments in addresses -- previously
		it insisted that they be balanced, but the 822 spec
		says that they should be ignored.
	Dump open file state to syslog upon receiving SIGUSR1 (for
		debugging).  This also evaluates ruleset 89, if set
		(with the null input), and logs the result.  This
		should be used sparingly, since the rewrite process
		is not reentrant.
	Change -qI, -qR, and -qS flags to be case-insensitive as
		documented in the Bat Book.
	If the mailer returned EX_IOERR or EX_OSERR, sendmail did not
		return an error message and did not requeue the message.
		Fix based on code from Roland Dirlewanger of
		Reseau Regional Aquarel, Bordeaux, France.
	Fix a problem that caused a seg fault if you got a 421 error
		code during some parts of connection initialization.
		I've only seen this when talking to buggy mailers on
		the other end, but it shouldn't give a seg fault in
		any case.  From Amir Plivatsky.
	Fix core dump caused by a ruleset call that returns null.
		Fix from Bryan Costales of ICSI.
	Full-Name: field was being ignored.  Fix from Motonori Nakamura
		of Kyoto University.
	Fix a possible problem with very long input lines in setproctitle.
		From P{r Emanuelsson.
	Avoid putting "This is a warning message" out on return receipts.
		Suggested by Douglas Anderson.
	Detect loops caused by recursive ruleset calls.  Suggested by
		Bryan Costales.
	Initialize non-alias maps during alias rebuilds -- they may be
		needed for parsing.  Problem noted by Douglas Anderson.
	Log sender address even if no message was collected in SMTP
		(e.g., if all RCPTs failed).  Suggested by Motonori
		Nakamura.
	Don't reflect the owner-list contents into the envelope sender
		address if the value contains ", :, /, or | (to avoid
		illegal addresses appearing there).
	Efficiency hack for toktype macro -- from Craig Partridge of
		BB&N.
	Clean up DNS error printing so that a host name is always
		included.
	Remember to set $i during queue runs.  Reported by Stephen
		Campbell of Dartmouth University.
	If the environment variable HOSTALIASES is set, use it during
		canonification as the name of a file with per-user host
		translations so that headers are properly mapped.  Reported
		by Anne Bennett of Concordia University.
	Avoid printing misleading error message if SMTP mailer (not
		using [IPC]) should die on a core dump.
	Avoid incorrect diagnosis of "file 1 closed" when it is caused
		by the other end closing the connection.  From
		Dave Morrison of Oracle.
	Improve several of the error messages printed by "mailq"
		to include a host name or other useful information.
	Add NetInfo preliminary support for NeXT systems.  From Vince
		DeMarco.
	Fix a glitch that sometimes caused :include:s that pointed to
		NFS filesystems that were down to give an "aliasing/
		forwarding loop broken" message instead of queueing
		the message for retry.  Noted by William C Fenner of
		the NRL Connection Machine Facility.
	Fix a problem that could cause a core dump if the input sequence
		had (or somehow acquired) a \231 character.
	Make sure that route-addrs always have <angle brackets> around
		them in non-SMTP envelopes (SMTP envelopes already do
		this properly).
	Avoid weird headers on unbalanced punctuation of the form:
		``Joe User <user)'' -- this caused reference to the
		null macro.  Fix from Rick McCarty of IO.COM.
	Fix a problem that caused an alias "user: user@local.host" to
		not have the QNOTREMOTE bit set; this caused configs
		to act as if FEATURE(notsticky) was defined even when
		it was not.  The effect of the problem was to make it
		very hard to to set up satellite sites that had a few
		local accounts, with everything else forwarded to a
		corporate hub.  Reported by Detlef Drewanz of the
		University of Rostock and Mark Frost of NCD.
	Change queuing to not call rulesets 3, {1 or 2}, 4 on header
		addresses.  This is more efficient (fewer name server
		calls) and fixes certain unusual configurations, such
		as those that have ruleset 4 do something that is
		non-idempotent unless a mailer-specific ruleset did
		something else.  Problem reported by Brian J. Coan
		of the Institute for Global Communications.
	Fix the "obsolete argument" routine in main to better understand
		new arguments.  For example, if you used ``sendmail
		-C config -v -q'' it would choke on the -q because
		the -C would stop looking for old-format arguments.
	Fix the code that was intended to allow two users to forward their
		mail to the same program and have them appear unique.
	Portability fixes for:
		SCO UNIX from Murray Kucherawy.
		SCO Open Server 3.2v4 from Philippe Brand.
		System V Release 4 from Rick Ellis and others.
		OSF/1 from Steve Campbell.
		DG/UX from Ben Mesander of the USGS and Bryan Curnutt
			of Stoner Associates.

		Solaris 2.3 from Casper H.S. Dik of the University
			of Amsterdam and John Caruso of University
			of Maryland.
		FreeBSD from Ollivier Robert.

		Linux from John Kennedy of California State University
			at Chico.
		Solaris 2.x from Tony Boner of the U.S. Air Force.
		NEXTSTEP 3.x from Vince DeMarco.
		HP-UX from various people.  NOTA BENE:  the location
			of the config file has moved to /usr/lib
			to match the HP-UX version of sendmail.
	CONFIG: Don't do any recipient rewriting on relay mailer;
		since this is intended only for internal use, the
		usual RFC 821/822/1123 rules can be relaxed.  The
		main point of this is to avoid munging (ugh) UUCP
		addresses when relaying internally.
	CONFIG: fix typo in mailer/uucp.m4 that mutilates list:;
		syntax addresses delivered via UUCP.  Solution
		provided by Peter Wemm.
	CONFIG: fix thumb-fumble in default UUCP relaying in ruleset
		zero; it caused double @ signs in addresses.  From
		Irving Reid of the University of Toronto.
	CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1
		from Markku Toijala of ICL Personal Systems Oy.
	CONFIG: Add trailing "." on pseudo-domains for consistency;
		this fixes a problem (noted by Al Whaley of Sunnyside)
		that made it hard to recognize your own pseudodomain
		names.
	CONFIG: catch "@host" syntax errors (i.e., null local-parts)
		rather than letting them get "local configuration
		error"s.  Problem noted by John Gardiner Myers.
	CONFIG: add uucp-uudom mailer variant, based on code posted
		by Spider Boardman <spider@Orb.Nashua.NH.US>; this
		has uucp-dom semantics but old UUCP syntax.  This
		also permits "uucp-old" as an alias for "uucp" and
		"uucp-new" as a synonym for "suucp" for consistency.
	CONFIG: add POP mailer support (from Kimmo Suominen
		<kim@grendel.lut.fi>).
	CONFIG: drop CSNET_RELAY support -- CSNET is long gone.
	CONFIG: fix bug caused with domain literal addresses (e.g.,
		``[128.32.131.12]'') when FEATURE(allmasquerade)
		was set; it would get an additional @masquerade.host
		added to the address.  Problem noted by Peter Wan
		of Georgia Tech.
	CONFIG: make sure that the local UUCP name is in $=w.  From
		Jim Murray of Stratus.
	CONFIG: changes to UUCP rewriting to simulate IDA-style "V"
		mailer flag.  Briefly, if you are sending to host
		"foo", then it rewrites "foo!...!baz" to "...!baz",
		"foo!baz" remains "foo!baz", and anything else has
		the local name prepended.
	CONFIG: portability fixes for HP-UX.
	DOC: several minor problems fixed in the Install & Op Guide.
	MAKEMAP: fix core dump problem on lines that are too long or
		which lack newline.  From Mark Delany.
	MAILSTATS: print sums of columns (total messages & kbytes
		in and out of the system).  From Tom Ferrin of UC
		San Francisco Computer Graphics Lab.
	SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES:
		On HP-UX, /etc/sendmail.cf has been moved to
			/usr/lib/sendmail.cf to match HP sendmail.
		Permissions have been tightened up on world-writable
			:include: files and accounts that have shells
			that are not listed in /etc/shells.  This may
			cause some .forward files that have worked
			before to start failing.
		SIGUSR1 dumps some state to the log.

8.6.4/8.6.4	1993/10/31
	Repair core-dump problem (write to read-only memory segment)
		if you fall back to the return-to-Postmaster case in
		savemail.  Problem reported by Richard Liu.
	Immediately diagnose bogus sender addresses in SMTP.  This
		makes quite certain that crackers can't use this
		class of attack.
	Reliability Fix:  check return value from fclose() and fsync()
		in a few critical places.
	Minor problem in initsys() that reversed a condition for
		redirecting the output channel on queue runs.  It's
		not clear this code even does anything.  From Eric
		Wassenaar of the Dutch National Institute for Nuclear
		and High-Energy Physics.
	Fix some problems that caused queue runs to do "too much work",
		such as double-reading the Errors-To: header.  From
		Eric Wassenaar.
	Error messages on writing the temporary file (including the
		data file) were getting suppressed in SMTP -- this
		fix causes them to be properly reported.  From Eric
		Wassenaar.
	Some changes to support AF_UNIX sockets -- this will only
		really become relevant in the next release, but some
		people need it for local patches.  From Michael
		Corrigan of UC San Diego.
	Use dynamically allocated memory (instead of static buffers)
		for macros defined in initsys() and settime(); since
		these can have different values depending on which
		envelope they are in.  From Eric Wassenaar.
	Improve logging to show ctladdr on to= logging; this tells you
		what uid/gid processes ran as.
	Fix a problem that caused error messages to be discarded if
		the sender address was unparseable for some reason;
		this was supposed to fall back to the "return to
		postmaster" case.
	Improve aliaswait backoff algorithm.
	Portability patches for Linux (8.6.3 required another header
		file) (from Karl London) and SCO UNIX.
	CONFIG: patch prog mailer to not strip host name off of envelope
		addresses (so that it matches local again).  From
		Christopher Davis.
	CONFIG: change uucp-dom mailer so that "<>" translates to $n;
		this prevents uux from seeing lines with null names like
		``From   Sat Oct 30 14:55:31 1993''.  From Motonori
		Nakamura of Kyoto University.
	CONFIG: handle <list:;> syntax correctly.  This isn't legal, but
		it shouldn't fail miserably.  From Motonori Nakamura.

8.6.2/8.6.2	1993/10/15
	Put a "successful delivery" message in the transcript for
		addresses that get return-receipts.
	Put a prominent "this is only a warning" message in warning
		messages -- some people don't read carefully enough
		and end up sending the message several times.
	Include reason for temporary failure in the "warning" return
		message.  Currently, it just says "cannot send for
		four hours".
	Fix the "Original message received" time generated for
		returntosender messages.  It was previously listed as
		the current time.  Bug reported by Eric Hagberg of
		Cornell University Medical College.
	If there is an error when writing the body of a message,
		don't send the trailing dot and wait for a response
		in sender SMTP, as this could cause the connection to
		hang up under some bizarre circumstances.  From Eric
		Wassenaar.
	Fix some server SMTP synchronization problems caused when
		connections fail during message collection.  From
		Eric Wassenaar.
	Fix a problem that can cause srvrsmtp to reject mail if the
		name server is down -- it accepts the RCPT but rejects
		the DATA command.  Problem reported by Jim Murray of
		Stratus.
	Fix a problem that can cause core dumps if the config file
		incorrectly resolves to a null hostname.  Reported by
		Allan Johannesen of WPI.
	Non-root use of -C flag, dangerous -f flags, and use of -oQ
		by non-root users were not put into
		X-Authentication-Warning:s as intended because the
		config file hadn't set the PrivacyOptions yet.  Fix
		from Sven-Ove Westberg of the University of Lulea.
	Under very odd circumstances, the alias file rebuild code
		could get confused as to whether a database was
		open or not.
	Check "vendor code" on the end of V lines -- this is
		intended to provide a hook for vendor-specific
		configuration syntax.  (This is a "new feature",
		but I've made an exception to my rule in a belief
		that this is a highly exceptional case.)
	Portability fixes for DG/UX (from Douglas Anderson of NCSC),
		SCO Unix (from Murray Kucherawy), A/UX, and OSF/1
		(from Jon Forrest of UC Berkeley)
	CONFIG: fix ``mailer:host'' form of UUCP relay naming.

8.6.1/8.6	1993/10/08
	Portability fixes for A/UX and Encore UMAX V.
	Fix error message handling -- if you had a name server down
		causing an error during parsing, that message was never
		propagated to the queue file.

8.6/8.6		1993/10/05
	Configuration cleanup: make it easier to undo IDENTPROTO in
		conf.h (other systems have the same bug).
	If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume
		getdtablesize() instead of sysconf(); a disturbingly
		large number of systems defined _SC_OPEN_MAX in the
		header files but don't have the syscall.
	Another patch to really truly ignore MX records in getcanonname
		if trymx == FALSE.
	Fix problem that caused the "250 IAA25499 Message accepted for
		delivery" message to be omitted if there was an error
		in the header of the message (e.g., a bad Errors-To:
		line).  Pointed out by Michael Corrigan of UCSD.
	Announce name of host we are chatting when we get errors; this
		is an IDA-ism suggested by Christophe Wolfhugel.
	Portability fixes for Alpha OSF/1 (from Anthony Baxter of the
		Australian Artificial Intelligence Institute), SCO Unix
		(from Murray Kucherawy of Hookup Communication Corp.),
		NeXT (from Vince DeMarco and myself), Linux (from
		Karl London <karl@borg.demon.co.uk>), BSDI (from
		Christophe Wolfhugel, and SVR4 on Dell (from Kimmo
		Suominen), AUX 3.0 on Macintosh, and ANSI C compilers.
	Some changes to get around gcc optimizer bugs.  From Takahiro
		Kanbe.
	Fix error recovery in queueup if another tf file of the same
		name already exists.  Problem stumbled over by Bill
		Wisner of The Well.
	Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes.
		Problem noted by Keith McMillan of Ameritech Services.
	Deal with group permissions properly when opening .forward and
		:include: files.  This relaxes the 8.1C restrictions
		slightly more.  This includes proper setting of groups
		when reading :include: files, allowing you to read some
		files that you should be able to read but have previously
		been denied unless you owned them or they had "other"
		read permission.
	Make certain that $j is in $=w (after the .cf is read) so that
		if the user is forced to override some silly system,
		MX suppression will still work.
	Fix a couple of efficiency problems where newstr was double-
		calling expensive routines.  In at least one case, it
		wasn't guaranteed that they would always return the
		same result.  Problem noted by Christophe Wolfhugel.
	Fix null pointer dereference in putoutmsg -- only on an error
		condition from a non-SMTP mailer.  From Motonori
		Nakamura.
	Macro expand "C" line class definitions before scanning so that
		"CX $Z" works.
	Fix problem that caused error message to be sent while still
		trying to send the original message if the connection
		is closed during a DATA command after getting an error
		on an RCPT command (pretty obscure).  Problem reported
		by John Myers of CMU.
	Fix reply to NOOP to be 250 instead of 200 -- this is a long
		term bug.
	Fix a nasty bug causing core dumps when returning the "warning:
		cannot deliver for N hours -- will keep trying" message;
		it only occurred if you had PostmasterCopy set and
		only on some architectures.  Although sendmail would
		keep trying, it would send error messages on each
		queue interval.  This is an important fix.
	Allow u and g options to take user and group names respectively.
	Don't do a chdir into the queue directory in -bt mode to make
		ruleset testing a bit easier.
	Don't allow users to turn off logging (using -oL) on the command
		line -- command line can only raise, not lower, logging
		level.
	Set $u to the original recipient on the SMTP transaction or on
		the command line.  This is only done if there is exactly
		one recipient.  Technically, this does not meet the
		specs, because it does not guarantee a domain on the
		address.
	Fix a problem that dumped error messages on bad addresses if
		you used the -t flag.  Problem noted by Josh Smith of
		Harvey Mudd College.
	Given an address such as ``<foo> <bar>'', auto-quote the first
		``<foo>'' part, giving ``"<foo>" <bar>''.  This is to
		avoid the problem of people who use angle brackets in
		their full name information.
	Fix a null pointer dereference if you set option "l", have
		an Errors-To: header in the message, and have Errors-To:
		defined in the config file H lines.  From J.R. Oldroyd.
	Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get
		wrong when compiling.  Suggested by Rick McCarty of TI.
	Fix a problem that could pass negative SIZE parameter if the
		df file got lost; this would cause servers to always
		give a temporary failure, making the problem even worse.
		Problem noted by Allan Johannesen of WPI.
	Add "ident" timeout (one of the "r" option selectors) for IDENT
		protocol timeouts (30s default).  Requested by Murray
		Kucherawy of HookUp Communication Corp. to handle bogus
		PC TCP/IP implementations.
	Change $w default definition to be just the first component of
		the domain name on config level 5.  The $j macro defaults
		to the FQDN; $m remains as before.  This lets well-behaved
		config files use any of the short, long, or subdomain
		names.
	Add makesendmail script in src to try to automate multi-architecture
		builds.  I know, this is sub-optimal, but it is still
		helpful.
	Fix very obscure race condition that can cause a queue run to
		get a queue file for an already completed job.  This
		problem has existed for years.  Problem noted by the
		long suffering Allan Johannesen of WPI.
	Fix a problem that caused the raw sender name to be passed to
		udbsender instead of the canonified name -- this caused
		it to sometimes miss records that it should have found.
	Relax check of name on HELO packet so that a program using -bs
		that claims to be itself works properly.
	Restore rewriting of $: part of address through 2, R, 4 in
		buildaddr -- this requires passing a lot of flags to get
		it right.  Unlike old versions, this ONLY rewrites
		recipient addresses, not sender addresses.
	Fix a bug that caused core dumps in config files that cannot
		resolve /file/name style addresses.  Fix from Jonathan
		Kamens of OpenVision Technologies.
	Fix problem with fcntl locking that can cause error returns to
		be lost if the lock is lost; this required fully
		queueing everything, dropping the envelope (so errors
		would get returned), and then re-reading the queue from
		scratch.
	Fix a problem that caused aliases that redefine an otherwise
		true address to still send to the original address
		if and only if the alias failed in certain bizarre
		ways (e.g, if they pointed at a list:; syntax address).
		Problem pointed out by Jonathan Kamens.
	Remove support for frozen configuration files.  They caused
		more trouble than it was worth.
	Fix problem that can cause error messages to get ignored when
		using both -odb and -t flags.  Problem noted by Rob
		McNicholas at U.C. Berkeley.
	Include all "normal" variations on hostname in $=w.  For example,
		if the host name is vangogh.cs.berkeley.edu, $=w will
		contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu.
	Add "restrictqrun" privacy flag -- without this, anyone can run
		the queue.
	Reset SmtpPhase global on initial connection creation so that
		messages don't come out with stale information.
	Pass an "ext" argument to lockfile so that error/log messages
		will properly reflect the true filename being locked.
	Put all [...] address forms into $=w -- this eliminates the need
		for MAXIPADDR in conf.h.  Suggested by John Gardiner
		Myers of CMU.
	Fix a bug that can cause qf files to be left around even after
		an SMTP RSET command.  Problem and fix from Michael
		Corrigan.
	Don't send a PostmasterCopy to errors when the Precedence: is
		negative.  Error reports still go to the envelope
		sender address.
	Add LA_SHORT for load averages.
	Lock sendmail.st file when posting statistics.
	Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to
		set the size of the TCP send and receive buffers; if you
		run over a slow slip line you may need to set these down
		(although it would be better to fix the SLIP implementation
		so that it's not necessary to recompile every program
		that does bulk data transfer).
	Allow null defaults on $( ... $) lookups.  Problem reported by
		Amir Plivatsky.
	Diagnose crufty S and V config lines.  This resulted from an
		observation that some people were using the SITE macro
		without the SITECONFIG macro first, which was causing
		bogus config files that were not caught.
	Fix makemap -f flag to turn off case folding (it was turning it
		on instead).  THIS IS A USER VISIBLE CHANGE!!!
	Fix a problem that caused multiple error messages to be sent if
		you used "sendmail -t -oem -odb", your system uses fcntl
		locking, and one of the recipient addresses is unknown.
	Reset uid earlier in include() so that recursive .forwards or
		:include:s don't use the wrong uid.
	If file descriptor 0, 1, or 2 was closed when sendmail was
		called, the code to recover the descriptor was broken.
		This sometimes (only sometimes) caused problems with the
		alias file.  Fix from Motonori Nakamura.
	Fix a problem that caused aliaswait to go into infinite recursion
		if the @:@ metasymbol wasn't found in the alias file.
	Improve error message on newaliases if database files cannot be
		opened or if running with no database format defined.
	Do a better estimation of the size of error messages when NoReturn
		is set.  Problem noted by P{r (Pell) Emanuelsson.
	Fix a problem causing the "c" option (don't connect to expensive
		mailers) to be ignored in SMTP.  Problem noted and the
		solution suggested by Robert Elz of The University of
		Melbourne.
	Improve connection caching algorithm by passing "[host]" to
		hostsignature, which strips the square brackets and
		returns the real name.  This allows mailertable entries
		to match regular entries.
	Re-enable Return-Receipt-To: -- people seem to want this stupid
		feature, even if it doesn't work right.
	Catch and log attempts to try the "wiz" command in server SMTP.
		This also ups the log level from LOG_NOTICE to LOG_CRIT.
	Be more generous at assigning $z to the home directory -- do this
		for programs that are specified through a .forward file.
		Fix from Andrew Chang of Sun Microsystems.
	Always save a fatal error message in preference to a non-fatal
		error message so that the "subject" line of return
		messages is the best possible.
	CONFIG: reduce the number of quotes needed to quote configuration
		parameters with commas: two quotes should work now, e.g.,
		define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local'').
	CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom
		connections (domain-ized UUCP).
	CONFIG: fix bug in default maps (-o must be before database file
		name).  Pointed out by Christophe Wolfhugel.
	CONFIG: add FEATURE(nodns) to state that we are not relying on
		DNS.  This would presumably be used in UUCP islands.
	CONFIG: add OSTYPE(nextstep) and OSTYPE(linux).
	CONFIG: log $u in Received: line.  This is in technical violation
		of the standards, since it doesn't guarantee a domain
		on the address.
	CONFIG: don't assume "m" in local mailer flags -- this means that
		if you redefine LOCAL_MAILER_FLAGS you will have to include
		the "m" flag should you want it.  Apparently some Solaris 2.2
		installations can't handle multiple local recipients.
		Problem noted by Josh Smith.
	CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults).
	CONFIG: change default version level from 4 to 5.
	CONFIG: add FEATURE(nullclient) to create a config file that
		forwards all mail to a hub without ever looking at the
		addresses in any detail.
	CONFIG: properly strip mailer: information off of relays when
		used to change .BITNET form into %-hack form.
	CONFIG: fix a problem that caused infinite loops if presented
		with an address such as "!foo".
	CONFIG: check for self literal (e.g., [128.32.131.12]) even if
		the reverse "PTR" mapping is broken.  There's a better
		way to do this, but the change is fairly major and I
		want to hold it for another release.  Problem noted by
		Bret Marquis.

8.5/8.5		1993/07/23
	Serious bug: if you used a command line recipient that was unknown
		sendmail would not send a return message (it was treating
		everything as though it had an SMTP-style client that
		would do the return itself).  Problem noted by Josh Smith.
	Change "trymx" option in getcanonname() to ignore all MX data,
		even during a T_ANY query.  This actually didn't break
		anything, because the only time you called getcanonname
		with !trymx was if you already knew there were no MX
		records, but it is somewhat cleaner.  From Motonori
		Nakamura.
	Don't call getcanonname from getmxrr if you already know there
		are no DNS records matching the name.
	Fix a problem causing error messages to always include "The
		original message was received ... from localhost".
		The correct original host information is now included.
	Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their
		version of "test" doesn't have the -x flag).  Change it
		to use -f instead.  From John Myers.
	CONFIG: 8.4 mistakenly set the default SMTP-style mailer to
		esmtp -- it should be smtp.
	CONFIG: send all relayed mail using confRELAY_MAILER (defaults
		to "relay" (a variant of "smtp") if MAILER(smtp) is used,
		else "suucp" if MAILER(uucp) is used, else "unknown");
		this cleans up the configs somewhat.  This fixes a serious
		problem that caused route-addrs to get mistaken as relays,
		pointed out by John Myers.  WARNING: this also causes
		the default on SMART_HOST to change from "suucp" to
		"relay" if you have MAILER(smtp) specified.

8.4/8.4		1993/07/22
	Add option `w'.  If you receive a message that comes to you because
		you are the best (lowest preference) target of an MX, and
		you haven't explicitly recognized the source MX host in
		your .cf file, this option will cause you to try the target
		host directly (as if there were no MX for it at all).  If
		`w' is not set, this case is a configuration error.
		Beware: if `w' is set, senders may get bogus errors like
		"message timed out" or "host unknown" for problems that
		are really configuration errors.  This option is
		disrecommended, provided only for compatibility with
		UIUC sendmail.
	Fix a problem that caused the incoming socket to be left open
		when sendmail forks after the DATA command.  This caused
		calling systems to wait in FIN_WAIT_2 state until the
		entire list was processed and the child closed -- a
		potentially prodigious amount of time.  Problem noted
		by Neil Rickert.
	Fix problem (created in 6.64) that caused mail sent to multiple
		addresses, one of which was a bad address, to completely
		suppress the sending of the message.  This changes
		handling of EF_FATALERRS somewhat, and adds an
		EF_GLOBALERRS flag.  This also fixes a potential problem
		with duplicate error messages if there is a syntax error
		in the header of a message that isn't noticed until late
		in processing.  Original problem pointed out by Josh Smith
		of Harvey Mudd College.  This release includes quite a bit
		of dickering with error handling (see below).
	Back out SMTP transaction if MAIL gets nested 501 error.  This
		will only hurt already-broken software and should help
		humans.
	Fix a problem that broke aliases when neither NDBM nor NEWDB were
		compiled in.  It would never read the alias file.
	Repair unbalanced `)' and `>' (the "open" versions are already
		repaired).
	Logging of "done" in dropenvelope() was incorrect: it would
		log this even when the queue file still existed.  Change
		this to only log "done" (at log level 11) when the
		queue file is actually removed.  From John Myers.
	Log "lost connection" in server SMTP at log level 20 if there
		is no pending transaction.  Some senders just close the
		connection rather than sending QUIT.
	Fix a bug causing getmxrr to add a dot to the end of unqualified
		domains that do not have MX records -- this would cause
		the subsequent host name lookup to fail.  The problem
		only occurred if you had FEATURE(nocanonify) set.
		Problem noted by Rick McCarty of Texas Instruments.
	Fix invocation of setvbuf when passed a -X flag -- I had
		unwittingly used an ANSI C extension, and this caused
		core dumps on some machines.
	Diagnose self-destructive alias loops on RCPT as well as EXPN.
		Previously it just gave an empty send queue, which
		then gave either "Need RCPT (recipient)" at the DATA
		(confusing, since you had given an RCPT command which
		returned 250) or just dropped the email, depending on
		whether you were running VERBose mode.  Now it usually
		diagnoses this case as "aliasing/forwarding loop broken".
		Unfortunately, it still doesn't adequately diagnose
		some true error conditions.
	Add internal concept of "warning messages" using 6xx codes.
		These are not reported only to Postmaster.  Unbalanced
		parens, brackets, and quotes are printed as 653 codes.
		They are always mapped to 5xx codes before use in SMTP.
	Clean up error messages to tell both the actual address that
		failed and the alias they arose from.  This makes it
		somewhat easier to diagnose problems.  Difficulty noted
		by Motonori Nakamura.
	Fix a problem that inappropriately added a ctladdr to addresses
		that shouldn't have had one during a queue run.  This
		caused error messages to be handled differently during
		a queue run than a direct run.
	Don't print the qf name and line number if you get errors during
		the direct run of the queue from srvrsmtp -- this was
		just extra stuff for users to crawl through.
	Put command line flags on second line of pid file so you can
		auto-restart the daemon with all appropriate arguments.
		Use "kill `head -1 /etc/sendmail.pid`" to stop the
		daemon, and "eval `tail -1 /etc/sendmail.pid`" to
		restart it.
	Remove the ``setuid(getuid())'' in main -- this caused the
		IDENT daemon to screw up.  This required that I change
		HASSETEUID to HASSETREUID and complicate the mode
		changing somewhat because both Ultrix and SunOS seem
		to have a bug causing seteuid() to set the saved uid
		as well as the effective.  The program test/t_setreuid.c
		will test to see if your implementation of setreuid(2)
		is appropriately functional.
	The FallBackMX (option V) handling failed to properly identify
		fallback to yourself -- most of the code was there,
		but it wasn't being enabled.  Problem noted by Murray
		Kucherawy of the University of Waterloo.
	Change :include: open timeout from ETIMEDOUT to an internal
		code EOPENTIMEOUT; this avoids adding "during SmtpPhase
		with CurHostName" in error messages, which can be
		confusing.  Reported by Jonathan Kamens of OpenVision
		Technologies.
	Back out setpgrp (setpgid on POSIX systems) call to reset the
		process group id.  The original fix was to get around
		some problems with recalcitrant MUAs, but it breaks
		any call from a shell that creates a process group id
		different from the process id.  I could try to fix
		this by diddling the tty owner (using tcsetpgrp or
		equivalent) but this is too likely to break other
		things.
	Portability changes:
		Support -M as equivalent to -oM on Ultrix -- apparently
			DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs
			instead of using standard flags.  Oh joy.  This
			behavior reported by Jon Giltner of University
			of Colorado.
		SGI IRIX  -- this includes several changes that should
			help other strict ANSI compilers.
		SCO Unix -- from Murray Kucherawy of HookUp Communication
			Corporation.
		Solaris running the Sun C compiler (which despite the
			documentation apparently doesn't define
			__STDC__ by default).
		ConvexOS from Eric Schnoebelen of Convex.
		Sony NEWS workstations and Omron LUNA workstations from
			Motonori Nakamura.
	CONFIG: add confTRY_NULL_MX_LIST to set option `w'.
	CONFIG: delete `C' and `e' from default SMTP mailers flags;
		several people have made a good argument that this
		creates more problems than it solves (although this
		may prove painful in the short run).
	CONFIG: generalize all the relays to accept a "mailer:host"
		format.
	CONFIG: move local processing in ruleset 0 into a new ruleset
		98 (8 on old sendmail).  Domain literal [a.b.c.d]
		addresses are also passed through this ruleset.
	CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined,
		internet-style addresses would "fall off the end" of
		ruleset zero and be interpreted as local -- however,
		the angle brackets confused the recursive call.
		These are now diagnosed as "Unrecognized host name".
	CONFIG: USENET rules weren't included in S0 because of a mistaken
		ifdef(`_MAILER_USENET_') instead of
		ifdef(`_MAILER_usenet_').  Problem found by Rein Tollevik
		of SINTEF RUNIT, Oslo.
	CONFIG: move up LOCAL_RULE_0 processing so that it happens very
		early in ruleset 0; this allows .mc authors to bypass
		things like the "short circuit" code for local addresses.
		Prompted by a comment by Bill Wisner of The Well.
	CONFIG: add confSMTP_MAILER to define the mailer used (smtp or
		esmtp) to send SMTP mail.  This allows you to default
		to esmtp but use a mailertable or other override to
		deal with broken servers.  This logic was pointed out
		to me by Bill Wisner.  Ditto for confLOCAL_MAILER.
	Changes to cf/sh/makeinfo.sh to make it portable to SVR4
		environments.  Ugly as sin.

8.3/8.3		1993/07/13
	Fix setuid problems introduced in 8.2 that caused messages
		like "Cannot create qfXXXXXX: Invalid argument"
		or "Cannot reopen dfXXXXXX: Permission denied".  This
		involved a new compile flag "HASSETEUID" that takes
		the place of the old _POSIX_SAVED_IDS -- it turns out
		that the POSIX interface is broken enough to break
		some systems badly.  This includes some fixes for
		HP-UX.  Also fixes problems where the real uid is
		not reset properly on startup (from Neil Rickert).
	Fix a problem that caused timed out messages to not report the
		addresses that timed out.  Error messages are also more
		"user friendly".
	Drop required bandwidth on connections from 64 bytes/sec to
		16 bytes/sec.
	Further Solaris portability changes -- doesn't require the BSD
		compatibility library.  This also adds a new
		"HASGETDTABLESIZE" compile flag which can be used if
		you want to use getdtablesize(2) instead of sysconf(2).
		These are loosely based on changes from David Meyer at
		University of Oregon.  This now seems to work, at least
		for quick test cases.
	Fix a problem that can cause duplicate error messages to be
		sent if you are in SMTP, you send to multiple addresses,
		and at least one of those addresses is good and points
		to an account that has a .forward file (whew!).
	Fix a problem causing messages to be discarded if checkcompat()
		returned EX_TEMPFAIL (because it didn't properly mark
		the "to" address).  Problem noted by John Myers.
	Fix dfopen to return NULL if the open failed; I was depending
		on fdopen(-1) returning NULL, which isn't the case.  This
		isn't serious, but does result in weird error diagnoses.
		From Michael Corrigan.
	CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of
		messages sent through UUCP-family mailers.  Suggested
		by Bill Wisner of The Well.
	CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified,
		include a "uucp-dom" mailer that uses domain-style
		addressing.  Suggested by Bill Wisner.
	CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match
		LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS.  Suggested by
		Christophe Wolfhugel.
	CONFIG: Add OSTYPE(aix3).  From Christophe Wolfhugel.

8.2/8.2		1993/07/11
	Don't drop out on config file parse errors in -bt mode.
	On older configuration files, assume option "l" (use Errors-To
		header) for back compatibility.  NOTE:  this DOES NOT
		imply an endorsement of the Errors-To: header in any way.
	Accept -x flag on AIX-3 as well as OSF/1.  Why, why, why???
	Don't log errors on EHLO -- it isn't a "real" error for an old
		SMTP server to give an error on this command, and
		logging it in the transcript can be confusing.  Fix
		from Bill Wisner.
	IRIX compatibility changes provided by Dan Rich
		<drich@sandman.lerc.nasa.gov>.
	Solaris 2 compatibility changes.  Provided by Bob Cunningham
		<bob@kahala.soest.hawaii.edu>, John Oleynick
		<juo@klinzhai.rutgers.edu>
	Debugging: -d17 was overloaded (hostsignature and usersmtp.c);
		move usersmtp (smtpinit and smtpmailfrom) to -d18 to
		match the other flags in that file.
	Flush transcript before fork in mailfile().  From Eric Wassenaar.
	Save h_errno in mci struct and improve error message display.
		Changes from Eric Wassenaar.
	Open /dev/null for the transcript if the create of the xf file
		failed; this avoids at least one possible null pointer
		reference in very weird cases.  From Eric Wassenaar.
	Clean up statistics gathering; it was over-reporting because of
		forks.  From Eric Wassenaar.
	Fix problem that causes old Return-Path: line to override new
		Return-Path: line (conf.c needs H_FORCE to avoid
		re-using old value).  From Motonori Nakamura.
	Fix broken -m flag in K definition -- even if -m (match only)
		was specified, it would still replace the key with the
		value.  Noted by Rick McCarty of Texas Instruments.
	If the name server timed out over several days, no "timed out"
		message would ever be sent back.  The timeout code
		has been moved from markfailure() to dropenvelope()
		so that all such failures should be diagnosed.  Pointed
		out by Christophe Wolfhugel and others.
	Relax safefile() constraints: directories in an include or
		forward path must be readable by self if the controlling
		user owns the entry, readable by all otherwise (e.g.,
		when reading your .forward file, you have to own and
		have X permission in it; everyone needs X permission in
		the root and directories leading up to your home);
		include files must be readable by anyone, but need not
		be owned by you.
	If _POSIX_SAVED_IDS is defined, setuid to the owner before
		reading a .forward file; this gets around some problems
		on NFS mounts if root permission is not exported and
		the user's home directory isn't x'able.
	Additional NeXT portability enhancements from Axel Zinser.
	Additional HP-UX portability enhancements from Brian Bullen.
	Add a timeout around SMTP message writes; this assumes you can
		get throughput of at least 64 bytes/second.  Note that
		this does not impact the "datafinal" default, which
		is separate; this is just intended to work around
		network clogs that will occur before the final dot
		is sent.  From Eric Wassenaar.
	Change map code to set the "include null" flag adaptively --
		it initially tries both, but if it finds anything
		matching without a null it never tries again with a
		null and vice versa.  If -N is specified, it never
		tries without the null and creates new maps with a
		null byte.  If -O is specified, it never tries with
		the null (for efficiency).  If -N and -O are specified,
		you get -NO (get it?) lookup at all, so this would
		be a bad idea.  If you don't specify either -N or -O,
		it adapts.
	Fix recognition of "same from address" so that MH submissions
		will insert the appropriate full name information;
		this used to work and got broken somewhere along the
		way.
	Some changes to eliminate some unnecessary SYSERRs in the
		log.  For example, if you lost a connection, don't
		bother reporting that fact on the connection you lost.
	Add some "extended debugging" flags to try to track down
		why we get occasional problems with file descriptor
		one being closed when execing a mailer; it seems to
		only happen when there has been another error in the
		same transaction.  This requires XDEBUG, defined
		by default in conf.h.
	Add "-X filename" command line flag, which logs both sides of
		all SMTP transactions.  This is intended ONLY for
		debugging bad implementations of other mailers; start
		it up, send a message from a mailer that is failing,
		and then kill it off and examine the indicated log.
		This output is not intended to be particularly human
		readable.  This also adds the HASSETVBUF compile
		flag, defaulted on if your compiler defines __STDC__.
	CONFIG: change SMART_HOST to override an SMTP mailer.  If you
		have a local net that should get direct connects, you
		will need to use LOCAL_NET_CONFIG to catch these hosts.
		See cf/README for an example.
	CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle
		sites that don't use the -d flag.
	CONFIG: hide recipient addresses as well as sender addresses
		behind $M if FEATURE(allmasquerade) is specified; this
		has been requested by several people, but can break
		local aliases.  For example, if you mail to "localalias"
		this will be rewritten as "localalias@masqueradehost";
		although initial delivery will work, replies will be
		broken.  Use it sparingly.
	CONFIG: add FEATURE(domaintable).  This maps unqualified domains
		to qualified domains in headers.  I believe this is
		largely equivalent to the IDA feature of the same name.
	CONFIG: use $U as UUCP name instead of $k.  This permits you
		to override the "system name" as your UUCP name --
		in particular, to use domain-ized UUCP names.  From
		Bill Wisner of The Well.
	CONFIG: create new mailer "esmtp" that always tries EHLO
		first.  This is currently unused in the config files,
		but could be used in a mailertable entry.

8.1C/8.1B	1993/06/27
	Serious security bug fix: it was possible to read any file on
		the system, regardless of ownership and permissions.
	If a subroutine returns a fully qualified address, return it
		immediately instead of feeding it back into rewriting.
		This fixes a problem with mailertable lookups.
	CONFIG: fix some M4 frotz (concat => CONCAT)

8.1B/8.1A	1993/06/12
	Serious bug fix: pattern matching backup algorithm stepped by
		two tokens in classes instead of one.  Found by Claus
		Assmann at University of Kiel, Germany.

8.1A/8.1A	1993/06/08
	Another mailertable fix....

8.1/8.1		1993/06/07
	4.4BSD freeze.  No semantic changes.
OpenPOWER on IntegriCloud
