I know there are some terrible servers out there, but I think we can
discount any such server as horribly broken. Rewriting message-ids would
cause threading problems any time the sender referred to their own
messages. So "format-patch --thread" would fail to work, and even
replying to your own message from your "sent" folder would fail.
