We've been using courier-imap for about five years now after
looking at Cyrus and other options.  I much prefer the Maildir
format to Cyrus' somewhat similar, but proprietary mail storage.

We're using courier-imap at several sites with 10s of thousands
of e-mail users without problems.

The UW IMAP server may be OK for small systems where security
isn't an issue (it can basically access anything the user owns or
can read), and it can be very slow with it's single-file mail
stores.

Another advantage of the Maildir storage is that it's fairly easy
to spread the load over multiple servers as there are no file
locking issues with Maildir.
