I've been asked several times about our setup using uw imapd. To avoid
repeating myself, I actually motivated myself enough to write up a small
page describing what we do/use. If you have any patches for uw imapd or
any other imap server, please tell me and I can work something up if I
can find the time.
url is http://www.carumba.com/imap/
I hope this is useful.
