Well, you'll first have to decide where you want your users to keep
their old mail.  Does everyone has it's own privat machine to do
his/her mail, or are there times that one is on a different machine,
yet still needs to access old mail?  In the latter case a pop3 server
isn't suited, it's geared to downloading *all* mail and stuffing it
locally. To bad when you do it whilst on a different machine:( IMAP on
the other hand was designed just to make this possible.  So if I where
you I would dedignate one machine to be the mail repository, have all
users receive mail there and stuff there old mail there too.

So make up your mind and use *IMAP*

That depends on what programs you use.

both can be solved with *(x)inet.d*

you should make it *relay* for them.

yep, and it should!
You get your mail with fetchmail, so there is no need to have the port
visible to the outside.
