Hmmm. If the _server_ has to provide a message-id, then all is not
well, in my opinion: a decent mail _client_ (MUA) would have provided
one already. I'd go so far as to say that lack of a client-provided
message-id deserves to be spam-rated.

A client-provided message-id of course won't match the pattern of
message-ids furnished by the MTA.
