I'm using Mailman version 2.1.23. Since late 2014, I've been successfully using the "Munge From" option under Privacy Options > Sender filters > "Action to take when anyone posts to the list from a domain with a DMARC Reject/Quarantine Policy." Mail from users using AOL, Yahoo and others with a DMARC policy of quarantine or reject had the FROM field munged:
FROM: John Doe <someu...@yahoo.com> becomes FROM: John Doe via Listname <listn...@ourdomain.com> Again, this has been working GREAT for over two years. Now, mysteriously, this has stopped working. When yahoo.com or AOL.com users post to our lists, the Munging is not working. When I query for a DMARC record from the mail server, it can see the record, so I think it's not a resolver issue. I'm really stumped... any pointers/ideas on where to look would be greatly appreciated! - Scott ------------------------------------------------------ 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
