It's a waste of time. Even if you conclusively demonstrated the offending
header was Message-Id: (and it almost certainly is a major player) what
would you do? Better is to avoid providers who think it fine to mess with
your mail. People wouldn't accept Royal Mail or the US Postal Service
doing it.
As for duplicates: are the mails sent to the list and the one sent back
duplicates? That is, identical in every regard?
