Just a user on a shared host, so no access to logs or the like, thought I would check here before raising issue with Host in case it was a know issue. Haven't touched these settings in a long time: dmarc_moderation_action is Munge From, which had been working just a few days ago, and stopped. Sounds like its off to the host provider and see if they did something recently. -- Richard Damon -- Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org

[Mailman-Users] New Problems with AOL & DMARC
I use Mailman versioon 2.1.25 on a shared host, and in the past couple of days, something seems to have changed, as posts from AOL users are no longer getting their from address munged like they were a week ago, and I am getting massive bounces for DMARC rejection when a poster from AOL posts. Has something changed with their settings, and is their anything I can do about it? -- Richard Damon -- Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org
