Any mail system that doesn't put message-id on its outgoing mail is
badly broken. Most mail I see without message-id is from spambots. I
realize that in 5322 it is a SHOULD, but SHOULD means "MUST unless you
have a really good reason to do something else" which they don't.

Any chance you can tell us who it is or what kind of software they are using?

The hacks other people suggested to add a message-id on the way in
will work, but the senders should really fix their mail software.
