ok, that was my next thought also, just wondering if anybody has found
another solution. out imap server is running under very heavy load, 6-12
is usual!
i know this is a bit of topic, but did anybody compare the performance
of uw-imap vs. cyrus imap? we have about 900 users here, unfortunatly
many of them have large mailboxes (200 mbyte is not seldom) and we have
to provide pop3 also!
