[Mailman-Users] Customize "From" when munging it for DMARC?

[Jordan Brown]

Is there a way to control the From value when it gets munged so we pass
DMARC?

Setting it to the list name interacts badly with outloook.com and
hotmail.com replies.  Since the From address really isn't used (because
there's a Reply-To), it seems like it could be anything that's at the
host domain - the request address, for instance.

Thanks.
