I'm not sure how that would be an issue, since the MUA would be creating
threads from one or more of the following fields;

``Subject'', ``In-Reply-To'' and ``References''

So it shouldn't matter if you've munged the ``From´´ field.

Sure, but there was no mention of LA publishing a DMARC policy.

I've also advocated rejecting the message, or accepting, thus allowing
the receiver to quarantine/reject the message, and would be my personal

However, you're right that I'd much rather see dmarc_moderation, than
from_as_list; because I really don't appreciate my "From:" field being
unnecessarily rewritten, especially if it causes my own Reply-To field
to be clobbered.
