rc.sendmail -- sendmail(8) startup script
The rc.sendmail script is used by /etc/rc at boot time to start
sendmail(8). It is meant to be sendmail(8) specific and not a generic
script for all MTAs. It is only called by /etc/rc if the rc.conf(5)
mta_start_script variable is set to /etc/rc.sendmail.
The rc.sendmail script can take an optional argument specifying the
action to perform. The available actions are:
start Starts both the MTA and the MSP queue runner.
stop Stops both the MTA and the MSP queue runner.
restart Restarts both the MTA and the MSP queue runner.
start-mta Starts just the MTA.
stop-mta Stops just the MTA.
restart-mta Restarts just the MTA.
start-mspq Starts just the MSP queue runner.
stop-mspq Stops just the MSP queue runner.
restart-mspq Restarts just the MSP queue runner.
If no action is specified, start is assumed.
The rc.sendmail script is also used by /etc/mail/Makefile to enable the
Makefile's start, stop, and restart targets.
The following variables affect the behavior of rc.sendmail. They are
defined in /etc/defaults/rc.conf and can be changed in /etc/rc.conf.
sendmail_enable
(str) If set to ``YES'', run the sendmail(8) daemon at system
boot time. If set to ``NO'', do not run a sendmail(8) daemon to
listen for incoming network mail. This does not preclude a
sendmail(8) daemon listening on the SMTP port of the loopback
interface. The ``NONE'' option is deprecated and should not be
used. It will be removed in a future release.
sendmail_flags
(str) If sendmail_enable is set to ``YES'', these are the flags
to pass to the sendmail(8) daemon.
sendmail_submit_enable
(bool) If set to ``YES'' and sendmail_enable is set to ``NO'',
run sendmail(8) using sendmail_submit_flags instead of
sendmail_flags. This is intended to allow local mail submission
via a localhost-only listening SMTP service required for running
sendmail(8) as a non-set-user-ID binary. Note that this does not
work inside jail(2) systems, as jails do not allow binding to
just the localhost interface.
sendmail_submit_flags
(str) If sendmail_enable is set to ``NO'' and
sendmail_submit_enable is set to ``YES'', these are the flags to
pass to the sendmail(8) daemon.
sendmail_outbound_enable
(bool) If set to ``YES'' and both sendmail_enable and
sendmail_submit_enable are set to ``NO'', run sendmail(8) using
sendmail_outbound_flags instead of sendmail_flags. This is
intended to allow local mail queue management for systems that do
not offer a listening SMTP service.
sendmail_outbound_flags
(str) If both sendmail_enable and sendmail_submit_enable are set
to ``NO'' and sendmail_outbound_enable is set to ``YES'', these
are the flags to pass to the sendmail(8) daemon.
sendmail_msp_queue_enable
(bool) If set to ``YES'', start a client (MSP) queue runner
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 ensures that nothing is left behind in the submission
queue.
sendmail_msp_queue_flags
(str) If sendmail_msp_queue_enable is set to ``YES'', these are
the flags to pass to the sendmail(8) daemon.
These variables are used to determine how the sendmail(8) daemons are
started:
# 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
To completely prevent any sendmail(8) daemons from starting, you must set
the following variables in /etc/rc.conf:
sendmail_enable="NO"
sendmail_submit_enable="NO"
sendmail_outbound_enable="NO"
sendmail_msp_queue_enable="NO"
rc.conf(5), rc(8), sendmail(8)
The rc.sendmail file appeared in FreeBSD 4.6.
