Yes.

Don't run the daemon,

  sendmail_enable="NO"

This does not affect how mail is sent...

...UNLESS...

The attempt fails. The mail will be queued, but there is no sendmail
daemon running to periodically process the queue.

If you are only sending local mail, this is not a concern. If you are
sending outgoing mail to other machines, you can run,

  sendmail_enable="YES"
  sendmail_flags="-q30m"

And the daemon will process the queue every 30 minutes but not listen
on port 25.
