Mark, would you expand on this a little, please? I am currently looking at a situation with Thunderbird. When one asks it to delete an IMAP mailbox, it tries to do so by moving it to the Trash. (I.e. using RENAME mailbox Trash/mailbox). This is a problem because some servers do not (and cannot) support a rename that has the effect of moving the mailbox within the hierarchy.
