... do I really need to elaborate on why I wrote "just to name *one* possibility"? Your own mails to a (simple) mailinglist, given that you'll likely already have a copy in your "Sent" folder as the on-list version comes back to you? Received mail matching several topics at once, and the user first copies it to archive folder A, then moves the original to folder B, all via IMAP? Versions of an e-mail that are *marked* deleted, but not yet expunged, and can still be seen/accessed/undeleted/moved/copied/... in *some* IMAP clients?
