I'm not sure why you would consider Cyrus "over the top".  Even for
a small user base, it is quite a nice solution.  The biggest factor in
choosing between Cyrus and IMAP-uw is probably the relative importance
of retaining classical unix inboxes in /var/mail -vs- improved system
security.  (IMAP-uw retains the classical mailboxes, but must run as
root or have -all- mailboxes readable by -anyone-.  Cyrus runs as a
non-priveleged user [nominally 'cyrus'], but forces all mailbox access
to be through IMAP or POP.)

I chose Cyrus a couple of years ago for the security.  Since then
there have been a few root-compromise security alerts against IMAP-uw;
but no alerts at all against Cyrus.  (And Cyrus was not fazed by the
username/password overrun attack - it just rejects it.)
