In fact, cyrus is a good example of a maildir derivative that maintains
indexes on the mailboxes. This is _bliss_ when listing large IMAP
folders - I have users who have 4000 message folders that open in

Learn to use folders, you say? Well, most of them have been shown how,
slowly and carefully in small, words, SOME FIVE TIMES, so I've given up.
