Read up about the interactions between DKIM, DMARC and mailing lists here: https://wiki.list.org/DEV/DKIM Either we change the From (and so need to set a Reply-To otherwise it becomes impossible to do a private reply, which is needed sometimes) or we get every google user booted off the list whenever a yahoo user posts. It sucks all round. Samba uses the last option listed in the table there. (Historically, we used to set reply-to to the mailing list, to avoid accidental private replies).

If I log into Mailman and go to 'Reply-To: header munging' it tells me that we aren't removing any existing 'Reply-To' headers and replies to list messages are directed to 'Poster', which, on the face of it, sounds like it is adding 'Reply-To' headers, but the 'help' says this: This option controls what Mailman does to the Reply-To: header in messages flowing through this mailing list. When set to Poster, no Reply-To: header is added by Mailman, although if one is present in the original message, it is not stripped. Setting this value to either This list or Explicit address causes Mailman to insert a specific Reply-To: header in all messages, overriding the header in the original message if necessary (Explicit address inserts the value of reply_to_address). This, to me, says we don't add or remove 'Reply-To' headers Rowland
