.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 affect 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 NO ,
|
|
do not run a
|
|
.Xr sendmail 8
|
|
daemon to listen for incoming network mail.
|
|
This does not preclude a
|
|
.Xr sendmail 8
|
|
daemon listening on the SMTP port of the loopback interface.
|
|
The
|
|
.Dq Li NONE
|
|
option is deprecated and should not be used.
|
|
It will be removed in a future release.
|
|
.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 ensures 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
|
|
.Ed
|
|
.Pp
|
|
To completely prevent any sendmail daemons from starting you must
|
|
set the following variables in
|
|
/etc/rc.conf:
|
|
.Bd -literal -offset indent
|
|
sendmail_enable="NO"
|
|
sendmail_submit_enable="NO"
|
|
sendmail_outbound_enable="NO"
|
|
sendmail_msp_queue_enable="NO"
