Re: Multiple message-ids.

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?
