Which in turn is part of what
control = submission
does (it also supplies missing From: and Date: headers which are the two
required headers).
Once you get your submission-from-clients Exim separated from your
MX-from-the-world Exim, this sort of thing becomes easier.
Message-Id: (per RFC2822) is optional but SHOULD be present. I guess that
is "less optional" than the just plain "optional" headers are. Fortunately,
almost every message we see in our corner of the world does have a
Message-Id: header. (Unfortunately, some we generate ourselves don't
(yet).)
