Yeah.. Maybe some day I should change the mailbox deletion to work by
sending expunge to all mails and then simply removing the empty mailbox.
This is how it works with multi-dbox, but not with others.

So you want to disallow deleting non-empty folders? Anyway, you need to
hook into struct mailbox.delete. See quota_mailbox_delete() in quota
plugin. box->opened=TRUE if it was a real selectable mailbox, while it's
FALSE if it was simply a directory (Maildir++ has only selectable
mailboxes).
