Regarding UW-IMAP mailserver

[Petey]

Using "Mac OSX Hacks", a handy little book by O'Reilly, I started up my own UW-IMAP mailserver on a Free BSD box. I want to provide POP/IMAP service for several domains that I own.

However--as anyone who has tried to set up their own mailserver probably knows--setting up an MTA if you are not an ISP is a pain in the proverbial arse. After talking to some fellow server nerds and reading up on it, I decided that the best route for me to take would be to provide POP/IMAP service for my domains, while I would leave the SMTP stuff to the users ISP. Basically, each user would have to configure their own mail client to send mail from their given address through their ISP SMTP account.

Unfortunately, all of the documentation I had was on how to set your mailserver up as a "full" mailserver--i.e., providing your own SMTP stuff.

How do I go about configuring my UW-IMAP mailserver so I can do this? Where, in other words, do I store the necessary user information and such?

Thanks,
