/usr/sbin/sendmail (for the sendmail or postfix MTA), when invoqued to
send mail, place the message to be sent in the local queue
(if it is considered local) or connects to the remote smtp port (if it is
consided non-local). When placed in the local queue, the local daemon will
pick it up there and procees it. But nothing there requires a daemon
listening on the smtp port on the local system.
