If you cannot use other format instead mbox, you already have you answer. It's uw-imap. Many peoples tell you uw-imap is very suck. Maybe it's true, maybe the code is not clean, but I'm running uw-imap for small groups (<1000 account) very fine and without any problem. If you can use Maildir, don't use UW-Imap. Because mbox is not scalable. You can use on very large with Maildir. Cyrus-imap is for lots of lots of account, because there using something like Database for storage and indexing. You can have two servers automaticaly synchronised etc... But Cyrus-Imap is more complexe than other. I don't known Dovecot. I've using courier-imap and work very fine. You don't need procmail for courier-imap. You can use procmail but it's not needed. The perf is very good with courier-imap (vs uw-imap where the perf is very poor when the number of mail increase).
