The
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.conf5
mta_start_script
variable is set to
/etc/rc.sendmail
The
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
script is also used by
/etc/mail/Makefile
to enable the
Makefile 'sstart , stop
and
restart
targets.
RC.CONF VARIABLES
The following variables affect the behavior of
.
They are defined in
/etc/defaults/rc.conf
and can be changed in
/etc/rc.conf
sendmail_enable
(Vt 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
(Vt str
)
If
sendmail_enable
is set to
``YES
''
these are the flags to pass to the
sendmail(8)
daemon.
sendmail_submit_enable
(Vt 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
(Vt 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
(Vt 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
(Vt 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
(Vt 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
(Vt 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
