The fuss involved people having paid no attention to the announcement of
Dng's DMARC-mitigation munging starting on December 6th, and so being
confused by that and the appended Reply-To. And some people, including
you, still aren't getting that, even though it got re-explained
yesterday, encore une fois.

Yes. But only where p=reject or p=quarantine..

No, there's no obligation for either of those, to ensure deliverability
of mail munged by the MLM software for DMARC-mitigation purposes.

Indeed, the Dng listadmins did exactly that, on Dec. 6th, following
instructions I provided. The whole thing was covered here at the time,
so I'm puzzled that so many people seem to have failed completely to
read the explanations.

I'm sorry, but how were the several explanations of this matter,
including those just yesterday, unclear?
