This is the from_is_list setting which controls DMARC mitigations applied to ALL messages. You also need to look at Privacy options... -> Sender filters settings dmarc_moderation_action and dmarc_quarantine_moderation_action which control the mitigations applied to messages From: domains that publish DMARC policies of reject and quarantine. > What happens, if I set the list not to add/change the Reply-To header, and > still set the list address in the Explicit Reply-To header field? I guess > Mailman will just ignore that field - or not? If reply_goes_to_list is Explicit address, mailman will add reply_to_address to Reply-To: and if that's the list posting address, it's no different from setting reply_goes_to_list to This list. If reply_goes_to_list is Poster, Mailman won't add anything to Reply-To: for this reason, but it will still honor first_strip_reply_to and add the original From: to Reply-To: if the From: is munged. > If there are better settings to accomplish the goals, this would be very > helpful. You need to do something to mitigate DMARC or all posts to the list From: domains that publish DMARC p=reject will be bounced by many recipients ISPs.
