Fetchmail Type Question

[Jon]

Hi,

Over the last couple of weeks I have been building a mail server for my
house.  All my email is currently managed by my ISP which doesn't offer
secure POP3, shell accounts or an easy way to create mailing lists.  

Originally, I had planned on having my ISP point the mx entry for my
domain
at my home server (on AT&T "broadband"). However, due to all the problems
that people have had with "broadband" ISP's blocking ports, I was thinking
that I would rather set up a general mailbox on my web-hosting ISP
(xeran.com) and then setup a program like fetchmail to pop
that one mailbox and deliver the mail to separate accounts on my 
mail server at home.  Is this possible????? 

IE. Email for jon, bill, and ed all end up at bigbox at xeran.com
and then I pop bigbox and deliver the mail to jon at home, bill at home and
ed at home

The mail server that I built is a Redhat 7.3 box with Postfix, Apache, 
Courier Imap, Squirrel Mail, and Mailman.

Thanks,
Jon

P.S. When is the term analog going to be cool again?  Is digital going to
become out dated? Is baseband going to be the next big marketing
buzzword?
