Take a look at the Trashed flag, and make sure it is necessary given the MVMSG command. I think we're trying to be too much like IMAP here, and (when a Deleted Items folder can exist) a Trashed flag may not be necessary.

Items to think about.

• Encourage implementations to implement deleted items folder (special folder? should it be treated specially in the protocol?)

• What about other special folders? Open issue about this (Sent?).

Thanks to Dan Karp for bringing this up.
