I strongly recommend that you avoid port 25 for remote submission -- the
anti-spam security measures have really screwed it up for any kind of
end-to-end use. E.g. if a Glasgow academic visits Cambridge they'd be out
of luck if they want to send email via the gla.ac.uk servers on port 25.

POP is a thoroughly bad idea too. It's one of the more popular ways for
our users to accidentally lose all their email through no fault of their
own.
