I'm not sure what your specific AOL issue is, but as I posted previously <https://mail.python.org/pipermail/mailman-users/2014-October/077908.html>, I don't see it, at least not in the form that you appear to. > Now I'm getting complaints from Outlook 2007 and Squirrelmail > users that the messages from Mailman show up as text attachments > that aren't automatically displayed or previewed. That is a problem with some MUAs. Some are just plain bad at rendering messages with message/rfc822 subparts like the DMARC wrapped messages and MIME format digests. > It looks like Outlook 2007 users can turn previewing on, but I don't > see any such options for Squirrelmail. There probably aren't any in Squirrelmail. > How have other Mailman admins dealt with this? Ultimately, I relented and set dmarc_moderation_action to Munge From. I didn't want to, but there were too many complaints about the wrapped messages. If I understand correctly, you at least think that AOL doesn't like your messages with munged from because of the address in Reply-To:. Note that the AOL SMTP response you posted earlier was a 421 status that is a retryable error. Did the retry succeed. If so, this is more like greylisting than rejection. > I wonder if it's possible to to make wrapped messages a user preference, > or have them only turned on for certain domains as discussed previously. > Is this a patch that would be accepted in the future? Mailman 2.1.18-1 has the ability to only apply DMARC mitigations to messages From: domains that publish DMARC p=reject and optionally p=quarantine policies. But, I think what you mean by "certain domains" is messages To: a certain domain like aol.com, and Mailman doesn't do that. It wouldn't be too difficult to patch Mailman to do that, but I have no plan to do that. There is no plan to make the choice between wrapping vs. munging From: a user option, but it could be considered for a future release. The bottom line is DMARC forces choices on a list manager, none of which are totally transparent to the list user experience. You can always set dmarc_moderation_action to reject and provide a rejection message which tells the poster that posts from domains with DMARC p=reject (or quarantine) policies are not accepted and they need to find another freemail ESP to use for posting. On the other hand, As I posted before, I don't see that your issue with AOL is a DMARC issue at all. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
