This is a solved problem, the "Rfc822.Sender" field should have
from the outset trumped the "Rfc822.From" field when determining
message origin, and the DMARC policy should be that of the "Sender"
domain.  Some MUAs already expose "Sender != From" by displaying
"From <sender> on behalf of <author>".  This needs to become standard
MUA behaviour.

I am coming around to the point of view.

Thanks for the moral support.  Message origin is subtle business.
In addition to "Sender" which is used by mailing lists and other
proxy agents, there is also "Resent-From" and friends.  I am rather
partial to "forwarding" messages not in-line or as attachments,
but as "resent" messages.

MUAs should expose message origin when different from author.

FWIW, the text is from the proposed charter, I didn't write any of it.

Yes, of course.
