AFAIK, you either have to have your mailer (sendmail) running all of the time
in daemon mode, or it has to be set up to be activated by inetd when someone
hits port 25 (smtp).  (I don't know whether sendmail works in this latter
mode, but some mailers do.)

If you don't have one of these going, you're not going to have reliable
inbound email.
