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

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:
Starts both the MTA and the MSP queue runner.
Stops both the MTA and the MSP queue runner.
Restarts both the MTA and the MSP queue runner.
Starts just the MTA.
Stops just the MTA.
Restarts just the MTA.
Starts just the MSP queue runner.
Stops just the MSP queue runner.
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_cert_create
(str) If sendmail_enable is set to “YES”, create a signed certificate /etc/mail/certs/host.cert representing /etc/mail/certs/host.key by the CA certificate in /etc/mail/certs/cacert.pem. This will enable connecting hosts to negotiate STARTTLS allowing incoming email to be encrypted in transit. sendmail(8) needs to be configured to use these generated files. The default configuration in /etc/mail/freebsd.mc has the required options in it.
sendmail_cert_cn
(str) If sendmail_enable is set to “YES” and sendmail_cert_create is set to “YES”, this is the Common Name (CN) of the certificate that will be created. If sendmail_cert_cn is not set, the system's hostname will be used. If there is no hostname set, “amnesiac” will be used.
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.
October 19, 2013 FreeBSD 12.0-RELEASE
