RC.SENDMAIL(8)		  BSD System Manager's Manual		RC.SENDMAIL(8)

NAME
     rc.sendmailsendmail(8) startup script

DESCRIPTION
     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.

RC.CONF VARIABLES
     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 submis‐
	     sion 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"
