It seems Mailman does support something like that: https://wiki.list.org/DEV/DMARC https://www.gnu.org/software/mailman/mailman-admin/sender-filters.html ...Okay, I've gone ahead and set dmarc_moderation_action to "Munge From" on all three lists. Changing the From address is annoying (sorry Murphy), but it only applies to messages from domains with p=reject DMARC entries, and the alternative is for those messages to not be deliverable properly. Incidentally, Gmail seems to accept such messages but send them to Spam. I set my Agora filter to never send to Spam, so I get a banner saying "This message was not sent to Spam because of a filter you created."
