The IETF's position is that this decision is up to the forwarding agent. If they change the Message-ID, that means they consider it a new message, and are taking authorship (perhaps with substantial quoting, but it's quoting, not forwarding). If they don't, it's not new, and From MUST contain the address placed there by the original author. (That's an RFC-2119 "must". This is why Mark is correct to say that Munge From is non-conforming.) The IETF has NO position on WHEN this should be done because it's not relevant to interoperability. My personal reasoning with respect to mailing list managers like Mailman which normally pass through all text/plain, and perhaps add some tags to Subject and prefix or suffix the body, is that users (including posters) would be quite annoyed if de-duping didn't work. And those of us who deal with mail in sophisticated ways would be quite upset if the Message-ID we give it doesn't correspond to the Message-ID distributed by the list and in the archive. > However, if you are just sending the body of the original message From: > the list, according to RFC 5322 et al, you are saying the list is the > author of that message body.

We do make an effort to identify the author, so I wouldn't say we're "claiming authorship". The problems are that we make it impossible to identify the author by the usual methods (filtering on email address), and it's ugly, especially for folks with MUAs that display only the display name (and of course we had a lot of people rather confused by this through most of 2014!)
