Qmail? Yuck, if you like something in qmail, try postfix instead... at least
it is djb-free, and DFSG-compliant.

UW-imap is a... horrible side-effect of bovines eating a lot of grass.
Courier is pretty decent, and IMHO the only other possible choice other than
Cyrus 2.1. Courier plays loose with the IMAP RFCs, though. While Cyrus is
anal-retentive on being thruly RFC-compliant. On the other hand, Cyrus uses
SASL (which means it can be a REAL pain to configure correctly).
Cyrus can handle a few hundred thousand users in a single badass box, I
don't think Courier can do that. Cyrus can cluster with a _flat_ mailbox
namespace, too. And it comes with a full set of proxies (lmtp, imap, pop3
and sieve proxies) if you need them.
Virtual domains using something like "[EMAIL PROTECTED]" is NOT
straightforward to setup with Cyrus 2.1, though. You need that? Go for
Courier, IMHO.
Cyrus 2.2 fixes the virtual domains, but it is alpha and not stable enough
yet. OTOH, it allows you to access your email using a news reader(!) or to
access your news using a mail client (yuck! :^P)...

Well, just mutt -f '{foo@localhost}' :-) And the Cyrus spool format is
quite well documented, thank you very much. It's just that you are
DEFINATELY not supposed to access it directly, ever, so nobody does :-)
(It looks like a MH spool, and you HAVE direct access to all the emails,
with all headers, one per file. Quite easy to process directly if you
really need to. But you will have to cyrreconstruct the indexes after
meddling with the spool...)
