Dave,
I don't expect nor are any our mail software designs, main mail
processors, distribution, dupe checkers, tracers, gateways or all other
mail utilities support a silly concept of multiple Message-id: headers
per message. Of course, it may exist but only one is truly valid. I
personally never seen or don't recall ever seeing multiple message-id:
lines and I can't imagine at this time what would be the effect other
than only the first or maybe the last one is used.
It is possible there was a mis-communication with your challenger in
regards to the References: header which includes a list of multiple
messages ids?

Folks,
The email-arch specification notes that Internet standards provide for
at most one Message-ID, but the document asserts that more than one
sometimes appear in a message. I put that in because that's been my
impression.
THe assertion has been challenged. Easiest way to resolve this is to
query the community.
So, Community, I'm querrying you:
Do you see multiple message-id's in messages?
If you do, what affect do they have?
