Somewhat. Most daemons can do fine without the socket listener and
invoke /usr/sbin/sendmail by default. Only ones that can't get
to /usr/sbin/sendmail (i.e.: chrooted daemons), but in my experience they
don't know how to talk SMTP either.
I guess it's legacy that MTA's start their SMTP listener by default.
You can set sendmail_enable="NO" in /etc/rc.conf to disable the listener. If
you set it to "NONE" sendmail will be totally off and all mail from daemons
invoking /usr/sbin/sendmail will end up in /var/spool/mqueue without being
processed further.
If you choose to go with the "NO" option, be sure to read and
update /etc/aliases. The difference between mail stacking up
in /var/spool/mqueue or /var/mail is only the packaging.
Informative reading: newaliases(8), crontab(5) and periodic(8).

Problem with today's modular software: they start with the modules
and never get to the software part.
