I delete duplicates before they are delivered to a mailbox.

... 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?
