Can someone flip the option in Mailman for DMARC please, it’s problematic as if one posts and does DMARC and has 
feedback on, our messages are  possibly rejected, and the feedback from a post is quite large.
The list is doing the DMARC handling (From rewrite) for senders with a
DMARC p=reject.
Oh, or someone just changed the config per your request. :)  I have
p=none but my From got rewritten on this message.

I think it's been doing this for ages. It was the first time I'd seen From rewriting in the wild iirc.

I'm not understanding what problem Jared is talking about.
