Strange. Settings for the list are: Replace the From: header address with the list's posting address to mitigate issues stemming from the original From: domain's DMARC or similar policies. NO Hide the sender of a message, replacing it with the list address (Removes From, Sender and Reply-To fields) NO Should any existing Reply-To: header found in the original message be stripped? If so, this will be done regardless of whether an explict Reply-To: header is added by Mailman or not. YES Where are replies to list messages directed? Poster is strongly recommended for most mailing lists. THIS LIST Explicit Reply-To: header. (FIELD IS EMPTY) To my understanding, this should not cause any of the effects described in my previous message. Every list subscriber should see who wrote a message (so the From should not be replaced by the list address) and we want to keep the discussions on the list (it is a discussion list for technical issues with the MacOS operating system), so we do not select "reply to poster". 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 there are better settings to accomplish the goals, this would be very helpful. Thank you, Christian -- Christian F.
