If you are willing to spend the money I can recommend you use CommuniGate
Pro (Stalker Software, www.stalker.com). It is a fast and very scalable
mail server (It does SMTP, POP3, IMAP, etc.).

We run a free webmail sevice and our original application was homegrown.
We ran into some scalability issues (becuase the software was never meant
to cope with 100000+ users). CommuniGate Pro is the answer for us.



    My opinions may have changed, but not the fact that I am right.
