Would this pass RFC compliance?
Technically, it probably does. The problem is that Mailman doesn't handle those mails, the MTA does. It would be reasonably easy to set up a filter and have the MTA pass the message to that filter. It's very ugly, though, especially if for some reason you have no display name to work with. A bigger problem, as stated what you've done is to set up an open relay. So you would need to either maintain a database of valid addresses forever, or do some crypto trickery so that only valid addresses would be forwarded. The latter would involve key management, etc. N.B. I read a very similar suggestion somewhere, probably in the DMARC Internet-Draft or in their FAQ. ------------------------------------------------------ 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
