.Dt RC.SENDMAIL 8
.Os
.Sh NAME
.Nm rc.sendmail
.Nd
.Xr sendmail 8
startup script
.Sh DESCRIPTION
The
.Nm
script is used by
.Pa /etc/rc
at boot time to start
.Xr sendmail 8 .
It is meant to be
.Xr sendmail 8
specific and not a generic script for all MTAs.
It is only called by
.Pa /etc/rc
if the
.Xr rc.conf 5
.Va mta_start_script
variable is set to
.Pa /etc/rc.sendmail .
.Pp
The
.Nm
script can take an optional argument specifying the action to
perform.
The available actions are:
.Bl -tag -width ".Cm restart-mspq"
.It Cm start
Starts both the MTA and the MSP queue runner.
.It Cm stop
Stops both the MTA and the MSP queue runner.
.It Cm restart
Restarts both the MTA and the MSP queue runner.
.It Cm start-mta
Starts just the MTA.
.It Cm stop-mta
Stops just the MTA.
.It Cm restart-mta
Restarts just the MTA.
.It Cm start-mspq
Starts just the MSP queue runner.
.It Cm stop-mspq
Stops just the MSP queue runner.
.It Cm restart-mspq
Restarts just the MSP queue runner.
.El
.Pp
If no action is specified,
.Cm start
is assumed.
.Pp
The
.Nm
script is also used by
.Pa /etc/mail/Makefile
to enable the
.Pa Makefile Ns 's
.Cm start , stop ,
and
.Cm restart
targets.
.Sh RC.CONF VARIABLES
The following variables effect the behavior of
.Nm .
They are defined in
.Pa /etc/defaults/rc.conf
and can be changed in
.Pa /etc/rc.conf .
.Bl -tag -width indent
.It Va sendmail_enable
.Pq Vt str
If set to
.Dq Li YES ,
run the
.Xr sendmail 8
daemon at system boot time.
If set to
.Dq Li NONE ,
do not run any
.Xr sendmail 8
daemons at system boot time.
.It Va sendmail_flags
.Pq Vt str
If
.Va sendmail_enable
is set to
.Dq Li YES ,
these are the flags to pass to the
.Xr sendmail 8
daemon.
.It Va sendmail_submit_enable
.Pq Vt bool
If set to
.Dq Li YES
and
.Va sendmail_enable
is set to
.Dq Li NO ,
run
.Xr sendmail 8
using
.Va sendmail_submit_flags
instead of
.Va sendmail_flags .
This is intended to allow local mail submission via
a localhost-only listening SMTP service required for running
.Xr sendmail 8
as a non-set-user-ID binary.
Note that this does not work inside
.Xr jail 2
systems as jails do not allow binding to just the localhost interface.
.It Va sendmail_submit_flags
.Pq Vt str
If
.Va sendmail_enable
is set to
.Dq Li NO
and
.Va sendmail_submit_enable
is set to
.Dq Li YES ,
these are the flags to pass to the
.Xr sendmail 8
daemon.
.It Va sendmail_outbound_enable
.Pq Vt bool
If set to
.Dq Li YES
and both
.Va sendmail_enable
and
.Va sendmail_submit_enable
are set to
.Dq Li NO ,
run
.Xr sendmail 8
using
.Va sendmail_outbound_flags
instead of
.Va sendmail_flags .
This is intended to allow local mail queue management
for systems that do not offer a listening SMTP service.
.It Va sendmail_outbound_flags
.Pq Vt str
If both
.Va sendmail_enable
and
.Va sendmail_submit_enable
are set to
.Dq Li NO
and
.Va sendmail_outbound_enable
is set to
.Dq Li YES ,
these are the flags to pass to the
.Xr sendmail 8
daemon.
.It Va sendmail_msp_queue_enable
.Pq Vt bool
If set to
.Dq Li YES ,
start a client (MSP) queue runner
.Xr sendmail 8
daemon at system boot time.
As of sendmail 8.12, a separate queue is used for command line
submissions.
The client queue runner assures that nothing is
left behind in the submission queue.
.It Va sendmail_msp_queue_flags
.Pq Vt str
If
.Va sendmail_msp_queue_enable
is set to
.Dq Li YES ,
these are the flags to pass to the
.Xr sendmail 8
daemon.
.El
.Pp
These variables are used to determine how the
.Xr sendmail 8
daemons are started:
.Pp
.Bd -literal -offset indent
# MTA
if (${sendmail_enable} == NONE)
        # Do nothing
else if (${sendmail_enable} == YES)
        start sendmail with ${sendmail_flags}
else if (${sendmail_submit_enable} == YES)
        start sendmail with ${sendmail_submit_flags}
else if (${sendmail_outbound_enable} == YES)
        start sendmail with ${sendmail_outbound_flags}
endif

# MSP Queue Runner
if (${sendmail_enable} != NONE &&
    [ -r /etc/mail/submit.cf] &&
    ${sendmail_msp_queue_enable} == YES)
        start sendmail with ${sendmail_msp_queue_flags}
endif
