Unless you have to support users who *need* mbox, go with
maildir.  Delivery to a maildir is atomic, while mbox is
guaranteed to give you a corrupt mailbox once in a while.

I use Courier-IMAP and Sqwebmail, both over SSL.  I see a lot of
recommendations for Squirrelmail, but it has a lot of overhead
(PHP: just what you need, Yet Another Security Hole).  Sqwebmail
has a simple, secure design (not saying Squirrelmail doesn't, i
can't comment there), is written in C, and runs as a CGI.  Very
fast and reliable.
