Specifically, I have.... + + The current versions of Linux are generally considered to be + great for hobbyists and anyone else who wants to learn Unix + inside and out, or wants to always have something to do, or + wants a machine for light-duty mostly personal use and not + high-volume multi-user purposes. + + However, for those who want a system that will just sit in + the background and work without a fuss handling thousands of + mail messages a day for lots of different users, it's not + (yet) stable enough to fit the bill. + + Unfortunately, there are no known shareware/freeware + implementations of any operating system that provides the + level of stability necessary to handle that kind of load + (i.e., there are no free lunches). + + If you're wedded to the Intel x86 platform and want to run + sendmail, we suggest you look at commercial implementations + of Unix such as Interactive, UnixWare, Solaris, or BSD/386 + (just a sample of the dozens of different versions of Unix + for Intel x86). + + Of all known vendor supported versions of Unix for Intel x86, + BSDI's BSD/386 is least expensive and the only one known to + currently ship with sendmail V8 pre-installed. Since sendmail + V8 is continuing to be developed at UC Berkeley, and BSD/386 + is a full BSD 4.4 implementation, this is obviously be the most + "native" sendmail V8 environment. +---------------------------------------------------------------------- + * When I use sendmail on an Intel x86 machine running OS/2, I have + some problems. Specifically, I have.... + + The OS/2 port of sendmail is known to have left out huge + chunks of the code and functionality of even much older + versions of sendmail, in large part because the underlying OS + just doesn't have the necessary hooks to make it happen. + This port is so broken that we make no attempt to provide any + kind of support for it. Try BSDI's BSD/386 instead. +---------------------------------------------------------------------- + * I'm connected to the network via a SLIP/PPP link. Sometimes my + sendmail process hangs (although it looks like part of the + message has been transfered). Everything else works. What's + wrong? + + Most likely, the problem isn't sendmail at all, but the low + level network connection. It's important that the MTU + (Maximum Transfer Unit) for the SLIP connection be set + properly at both ends. If they disagree, large packets will + be trashed and the connection will hang. +---------------------------------------------------------------------- + * I just upgraded to 8.x and suddenly I'm getting messages in my + syslog of the form "collect: I/O error on connection". What is + going wrong? + + Nothing. This is just a diagnosis of a condition that had + not been diagnosed before. If you are getting a lot of these + from a single host, there is probably some incompatibility + between 8.x and that host. If you get a lot of them in + general, you may have network problems that are causing + connections to get reset. +---------------------------------------------------------------------- + * I just upgraded to 8.x and now when my users try to forward their + mail to a program they get an "illegal shell" message and their + mail is not delivered. What's wrong? + + In order for people to be able to run a program from their + .forward file, 8.x insists that their shell (that is, the + shell listed for that user in the passwd entry) be a "valid" + shell, meaning a shell listed in /etc/shells. If /etc/shells + does not exist, a default list is used, typically consisting + of /bin/sh and /bin/csh. + + This is to support environments that may have NFS-shared + directories mounted on machines on which users do not have + login permission. For example, many people make their + file server inaccessible for performance or security + reasons; although users have directories, their shell on + the server is /usr/local/etc/nologin or some such. If you + allowed them to run programs anyway you might as well let + them log in. + + If you are willing to let users run programs from their + .forward file even though they cannot telnet or rsh in (as + might be reasonable if you run smrsh to control the list of + programs they can run) then add the line + + /SENDMAIL/ANY/SHELL/ + + to /etc/shells. This must be typed exactly as indicated, + in caps, with the trailing slash. NOTA BENE: DO NOT + list /usr/local/etc/nologin in /etc/shells -- this will + open up other security problems. +---------------------------------------------------------------------- + * I just upgraded to 8.x and suddenly connections to the SMTP port + take a long time. What is going wrong? + + It's probably something weird in your TCP implementation that + makes the IDENT code act oddly. On most systems V8 tries to + do a ``callback'' to the connecting host to get a validated + user name (see RFC 1413 for detail). If the connecting host + does not support such a service it will normally fail quickly + with "Connection refused", but certain kinds of packet + filters and certain TCP implementations just time out. + + To test this, set the IDENT timeout to zero using + ``OrIdent=0'' in the configuration file. This will + completely disable all use of the IDENT protocol. + + Another possible problem is that you have your name server + and/or resolver configured improperly. Make sure that all + "nameserver" entries in /etc/resolv.conf point to functional + servers. If you are running your own server make certain + that all the servers listed in your root cache (usually + called something like "/var/namedb/root.cache"; see your + /etc/named.boot file to get your value) are up to date. + Either of these can cause long delays. +---------------------------------------------------------------------- + * I just upgraded to 8.x and suddenly I get errors such as ``unknown + mailer error 5 -- mail: options MUST PRECEDE recipients.'' What is + going wrong? + + You need OSTYPE(systype) in your .mc file -- otherwise the + configurations use a default that probably disagrees with + your local mail system. See cf/README for details. +---------------------------------------------------------------------- + * Under V8, the "From " header gets mysteriously munged when I send + to an alias. + + ``It's not a bug, it's a feature.'' This happens when you + have a "owner-list" alias and you send to "list". V8 + propagates the owner information into the envelope sender + field (which appears as the "From " header on UNIX mail or as + the Return-Path: header) so that downstream errors are + properly returned to the mailing list owner instead of to the + sender. In order to make this appear as sensible as possible + to end users, I recommend making the owner point to a + "request" address -- for example: + + list: :include:/path/name/list.list + owner-list: list-request + list-request: eric + + This will make message sent to "list" come out as being "From + list-request" instead of "From eric". +---------------------------------------------------------------------- + * I am trying to use MASQUERADE_AS (or the user database) to + rewrite from addresses, and although it works in the From: header + line, it doesn't work in the envelope (e.g., the "From " line). + + Believe it or not, this is intentional. The interpretation + of the standards by the V8 development group was that this + was an inappropriate rewriting, and that if the rewriting + were incorrect at least the envelope would contain a valid + return address. Other people have since described scenarios + where the envelope cannot be correct without this rewriting, + so 8.7 will have an option to rewrite both header and + envelope. ---------------------------------------------------------------------- * I want to run Sendmail version 8 on my DEC system, but you don't have MAIL11V3 support in sendmail.

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.

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!

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 (the same as -bv). + ``/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.

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 disasterous 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 behaviour. 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. + 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.

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 setuid 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 propogate environment + variables into children. "E<envar>" will propogate + 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 wierd I haven't thought of. + Suggested by Barry Shein of Software Tool & Die. + SECURITY: .forward files cannot be symbolic links.

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 behaviour. 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.

I would like to get +some feedback from you on a few items, if you have time. + +There are two programs, mailprio_mkdb and mailprio (source below). + +mailprio_mkdb reads maillog files and creates a DB file of address vs. +delay.

One thing that +would make this information a lot more accurate is if sendmail could log +a "transaction delay" (on failures also), as well as total delivery delay. +Perhaps, as an option, it could maintain the DB file itself? + +mailprio then simply reads a list of addresses from stdin (the mailing +list), and tries to prioritize them according to the info the database. +It collects comment lines and other junk at the top of the file; all +mailprio does is reorder lines, the actual text of the file should +be unchanged to the extent that you can verify it with: + sort sorted_list > checkit; sort mailing-list | diff - checkit +Users with no delay information are put next. The prioritized list is last. +Of course, this function could also be built-into sendmail (eventually). + +Putting "new account" info at the top with the current averaging function +probably adversly affects the prioritized list (at least in the short +term), but putting it at the bottom would not really give the new accounts +a fair chance. I suspect this isn't that big of a problem. I'm running +this here on a list with 461 accounts and about 10 messages per day so +I'll see how it goes. I'll keep some stats on delay times and see what +happens. + +Another thing that would help this situation, is if sendmail had the queue +ordered by site (but you already know this). If you ever get to do per +site queuing you should consider "blocking" a queue for some short period +of time if a connection fails to that site [sendmail does this inside a +single process on a per account basis now right?]; this would allow multiple +sendmails to quickly skip over those sites for people like me that run: + + for i in 1 2 3 4 5 6 7 8 ; do daemon sendmail -q; done + +to flush a queue that has gotten behind.

-feel free to develop your own. -.pp -One general point applies to all of these philosophies: -it is almost always a mistake -to try to do full host route resolution. -For example, -if you are on a UUCP-only site -and you are trying to get names of the form -.q user@host -to the Internet, -it does not pay to route them to -.q xyzvax!decvax!ucbvax!c70!user@host -since you then depend on several links not under your control, -some of which are likely to misparse it anyway. -The best approach to this problem -is to simply forward the message for -.q user@host -to -.q xyzvax -and let xyzvax -worry about it from there. -In summary, -just get the message closer to the destination, -rather than determining the full path. -.sh 4 "Large site, many hosts \*- minimum information" -.pp -Berkeley is an example of a large site, -i.e., more than two or three hosts -and multiple mail connections. -We have decided that the only reasonable philosophy -in our environment -is to designate one host as the guru for our site. -It must be able to resolve any piece of mail it receives. -The other sites should have the minimum amount of information -they can get away with. -In addition, -any information they do have -should be hints rather than solid information. -.pp -For example, -a typical site on our local ether network is -.q monet -(actually -.q monet.CS.Berkeley.EDU ). -When monet receives mail for delivery, -it checks whether it knows -that the destination host is directly reachable; -if so, mail is sent to that host. -If it receives mail for any unknown host, -it just passes it directly to -.q ucbvax.CS.Berkeley.EDU , -our master host. -Ucbvax may determine that the host name is illegal -and reject the message, -or may be able to do delivery. -However, it is important to note that when a new mail connection is added, -the only host that -.i must -have its tables updated -is ucbvax; -the others -.i may -be updated if convenient, -but this is not critical. -.pp -This picture is slightly muddied -due to network connections that are not actually located -on ucbvax. -For example, -some UUCP connections are currently on -.q ucbarpa. -However, -monet -.i "does not" -know about this; -the information is hidden totally between ucbvax and ucbarpa. -Mail going from monet to a UUCP host -is transferred via the ethernet -from monet to ucbvax, -then via the ethernet from ucbvax to ucbarpa, -and then is submitted to UUCP. -Although this involves some extra hops, -we feel this is an acceptable tradeoff. -.pp -An interesting point is that it would be possible -to update monet -to send appropriate UUCP mail directly to ucbarpa -if the load got too high; -if monet failed to note a host as connected to ucbarpa -it would go via ucbvax as before, -and if monet incorrectly sent a message to ucbarpa -it would still be sent by ucbarpa -to ucbvax as before. -The only problem that can occur is loops, -for example, -if ucbarpa thought that ucbvax had the UUCP connection -and vice versa. -For this reason, -updates should -.i always -happen to the master host first. -.pp -This philosophy results as much from the need -to have a single source for the configuration files -(typically built using -.i m4 \|(1) -or some similar tool) -as any logical need. -Maintaining more than three separate tables by hand -is essentially an impossible job. -.sh 4 "Small site \*- complete information" -.pp -A small site -(two or three hosts and few external connections) -may find it more reasonable to have complete information -at each host. -This would require that each host -know exactly where each network connection is, -possibly including the names of each host on that network. -As long as the site remains small -and the configuration remains relatively static, -the update problem will probably not be too great. -.sh 4 "Single host" -.pp -This is in some sense the trivial case. -The only major issue is trying to insure that you don't -have to know too much about your environment. -For example, -if you have a UUCP connection -you might find it useful to know about the names of hosts -connected directly to you, -but this is really not necessary -since this may be determined from the syntax. -.sh 4 "A completely different philosophy" -.pp -This is adapted from Bruce Lilly. -Any errors in interpretation are mine. -.pp -Do minimal changes in ruleset 3: -fix some common but unambiguous errors (e.g. trailing dot on domains) and -hide bang paths foo!bar into bar@foo.UUCP. -The resulting "canonical" form is any valid RFC822/RFC1123/RFC976 address. -.pp -Ruleset 0 does the bulk of the work. -It removes the trailing "@.UUCP" that hides bang paths, -strips anything not needed to resolve, -e.g. the phrase from phrase <route-addr> and from named groups, -rejects unparseable addresses using $#error, -and finally -resolves to a mailer/host/user triple. -Ruleset 0 is rather lengthy -as it has to handle 3 basic address forms: -RFC976 bang paths, -RFC1123 %-hacks -(including vanilla RFC822 local-part@domain), -and RFC822 source routes. -It's also complicated by having to handle named lists. -.pp -The header rewriting rulesets 1 and 2 -remove the trailing "@.UUCP" that hides bang paths. -Ruleset 2 also strips the $# mailer $@ host (for test mode). -.pp -Ruleset 4 does absolutely nothing. -.pp -The per-mailer rewriting rulesets conform the envelope and -header addresses to the requirements of the specific -mailer. -.pp -Lots of rulesets-as-subroutines are used. -.pp -As a result, header addresses are subject to minimal munging -(per RFC1123), and the general plan is per RFC822 sect. 3.4.10. -.sh 3 "Relevant issues" -.pp -The canonical form you use -should almost certainly be as specified in -the Internet protocols -RFC819 and RFC822. -Copies of these RFC's are included on the -.i sendmail -tape -as -.i doc/rfc819.lpr -and -.i doc/rfc822.lpr . -.pp -RFC822 -describes the format of the mail message itself. -.i Sendmail -follows this RFC closely, -to the extent that many of the standards described in this document -can not be changed without changing the code. -In particular, -the following characters have special interpretations: -.(b -< > ( ) " \e -.)b -Any attempt to use these characters for other than their RFC822 -purpose in addresses is probably doomed to disaster. -.pp -RFC819 -describes the specifics of the domain-based addressing. -This is touched on in RFC822 as well. -Essentially each host is given a name -which is a right-to-left dot qualified pseudo-path -from a distinguished root. -The elements of the path need not be physical hosts; -the domain is logical rather than physical. -For example, -at Berkeley -one legal host might be -.q a.CC.Berkeley.EDU ; -reading from right to left, -.q EDU -is a top level domain -comprising educational institutions, -.q Berkeley -is a logical domain name, -.q CC -represents the Computer Center, -(in this case a strictly logical entity), -and -.q a -is a host in the Computer Center. -.pp -Beware when reading RFC819 -that there are a number of errors in it. -.sh 3 "How to proceed" -.pp -Once you have decided on a philosophy, -it is worth examining the available configuration tables -to decide if any of them are close enough -to steal major parts of. -Even under the worst of conditions, -there is a fair amount of boiler plate that can be collected safely. -.pp -The next step is to build ruleset three. -This will be the hardest part of the job. -Beware of doing too much to the address in this ruleset, -since anything you do will reflect through -to the message. -In particular, -stripping of local domains is best deferred, -since this can leave you with addresses with no domain spec at all. -Since -.i sendmail -likes to append the sending domain to addresses with no domain, -this can change the semantics of addresses. -Also try to avoid -fully qualifying domains in this ruleset. -Although technically legal, -this can lead to unpleasantly and unnecessarily long addresses -reflected into messages. -The Berkeley configuration files -define ruleset nine -to qualify domain names and strip local domains. -This is called from ruleset zero -to get all addresses into a cleaner form. -.pp -Once you have ruleset three finished, -the other rulesets should be relatively trivial. -If you need hints, -examine the supplied configuration tables. -.sh 3 "Testing the rewriting rules \*- the \-bt flag" -.pp -When you build a configuration table, -you can do a certain amount of testing -using the -.q "test mode" -of -.i sendmail . -For example, -you could invoke -.i sendmail -as: -.(b -sendmail \-bt \-Ctest.cf -.)b -which would read the configuration file -.q test.cf -and enter test mode. -In this mode, -you enter lines of the form: -.(b -rwset address -.)b -where -.i rwset -is the rewriting set you want to use -and -.i address -is an address to apply the set to. -Test mode shows you the steps it takes -as it proceeds, -finally showing you the address it ends up with. -You may use a comma separated list of rwsets -for sequential application of rules to an input. -For example: -.(b -3,1,21,4 monet:bollard -.)b -first applies ruleset three to the input -.q monet:bollard. -Ruleset one is then applied to the output of ruleset three, -followed similarly by rulesets twenty-one and four. -.pp -If you need more detail, -you can also use the -.q \-d21 -flag to turn on more debugging. -For example, -.(b -sendmail \-bt \-d21.99 -.)b -turns on an incredible amount of information;

This file is +intended as a supplement to the CERT advisory CA-93:16.sendmail.vulnerability, +and to the software, smrsh.c, written by Eric Allman. + + + +The smrsh(8) program is intended as a replacement for /bin/sh in the +program mailer definition of sendmail(8). This README file describes +the steps needed to compile and install smrsh. + +smrsh is a restricted shell utility that provides the ability to +specify, through a configuration, an explicit list of executable +programs. When used in conjunction with sendmail, smrsh effectively +limits sendmail's scope of program execution to only those programs +specified in smrsh's configuration. + +smrsh has been written with portability in mind, and uses traditional +Unix library utilities. As such, smrsh should compile on most +Unix C compilers. + + + +To compile smrsh.c, use the following command: + +host.domain% cc -o smrsh smrsh.c + +For machines that provide dynamic linking, it is advisable to compile +smrsh without dynamic linking. As an example with the Sun Microsystems +compiler, you should compile with the -Bstatic option. + +host.domain% cc -Bstatic -o smrsh smrsh.c + + +Choose a directory that smrsh will reside in. We will use the traditional +/usr/local/etc directory for the remainder of this document. + +As root, install smrsh in /usr/local/etc directory, with mode 511. + +host.domain# mv smrsh /usr/local/etc +host.domain# chmod 511 /usr/local/etc/smrsh + + + +Next, determine the list of commands that smrsh should allow sendmail +to run. This list of allowable commands can be determined by: + + 1. examining your /etc/aliases file, to indicate what commands + are being used by the system. + + 2. surveying your host's .forward files, to determine what + commands users have specified. + +See the man page for aliases(5) if you are unfamiliar with the format of +these specifications. Additionally, you should include in the list, +popular commands such as /usr/ucb/vacation. + +You should NOT include interpreter programs such as sh(1), csh(1), +perl(1), uudecode(1) or the stream editor sed(1) in your list of +acceptable commands. + + +You will next need to create the directory /usr/adm/sm.bin and populate +it with the programs that your site feels are allowable for sendmail +to execute. This directory is explicitly specified in the source +code for smrsh, so changing this directory must be accompanied with +a change in smrsh.c. + + +You will have to be root to make these modifications. + +After creating the /usr/adm/sm.bin directory, either copy the programs +to the directory, or establish links to the allowable programs from +/usr/adm/sm.bin. Change the file permissions, so that these programs +can not be modified by non-root users. If you use links, you should +ensure that the target programs are not modifiable. + +To allow the popular vacation(1) program by creating a link in the +/usr/adm/sm.bin directory, you should: + +host.domain# cd /usr/adm/sm.bin +host.domain# ln -s /usr/ucb/vacation vacation + + + + +After populating the /usr/adm/sm.bin directory, you can now configure +sendmail to use the restricted shell. Save the current sendmail.cf +file prior to modifying it, as a prudent precaution. + +Typically, the program mailer is defined by a single line in the +sendmail configuration file, sendmail.cf. This file is traditionally +found in the /etc, /usr/lib or /etc/mail directories, depending on +the UNIX vendor. + +If you are unsure of the location of the actual sendmail configuration +file, a search of the strings(1) output of the sendmail binary, will +help to locate it. + +In order to configure sendmail to use smrsh, you must modify the Mprog +definition in the sendmail.cf file, by replacing the /bin/sh specification +with /usr/local/etc/smrsh. + +As an example: + +In most Sun Microsystems' sendmail.cf files, the line is: +Mprog, P=/bin/sh, F=lsDFMeuP, S=10, R=20, A=sh -c $u + +which should be changed to: +Mprog, P=/usr/local/etc/smrsh, F=lsDFMeuP, S=10, R=20, A=sh -c $u + ^^^^^^^^^^^^^^^^^^^^ + +A more generic line may be: +Mprog, P=/bin/sh, F=lsDFM, A=sh -c $u + +and should be changed to; +Mprog, P=/usr/local/etc/smrsh, F=lsDFM, A=sh -c $u + + +After modifying the Mprog definition in the sendmail.cf file, if a frozen +configuration file is being used, it is essential to create a new one. +You can determine if you need a frozen configuration by discovering +if a sendmail.fc file currently exists in either the /etc/, /usr/lib, +or /etc/mail directories. The specific location can be determined using +a search of the strings(1) output of the sendmail binary. + +In order to create a new frozen configuration, if it is required: +host.domain# /usr/lib/sendmail -bz + +Now re-start the sendmail process. An example of how to do this on +a typical system follows: + +host.domain# /usr/bin/ps aux | /usr/bin/grep sendmail +root 130 0.0 0.0 168 0 ?
