Some IMAP servers  (UW-IMAP at least, maybe others...) store mailbox 
metadata in a pseudo-message with the subject "DON'T DELETE THIS MESSAGE 
-- FOLDER INTERNAL DATA" which is not normally visible via IMAP *unless* 
you're using the mailbox directly on the mailserver (e.g. with a MUA 
that reads mbox or maildir structures directly) or via POP or have 
migrated a mailstore from UW-IMAP to another IMAP server at the 
filesystem level rather than over IMAP.
