From: paul(_at_)pscs(_dot_)co(_dot_)uk, ietf-822(_at_)ietf(_dot_)org
because we both, "collaboratively", wrote the message. However, this

multiple From addresses is not "normal".
Paul,
You need to translate this technical philosophy into client/server
protocol rule which means that the authoring domain has authorized
resigning with a DMARC policy. Otherwise, its will be detected as an
unauthorized signer, spoofed mail.
No, all you need to do is admit that the mailing list server sent the
message that came from the mailing list server - so set that to be the
From/return-path.
Then, it's not spoofed, it doesn't upset DKIM/DMARC, and it all works fine.
The only down-side is that the From address has been changed - but I'm
not really convinced that's enough of a down-side to warrant all the
shenanigans to get it to work any other way.
This doesn't help anonymous forwarders, but, personally, I think those
should be treated as the special case, rather than mailing lists.
