My understanding is that DMARC alignment depends on both SPF and DKIM and that if a test using either protocol passes, then a DMARC will pass. This is probably an oversimplification, but I'm exploring the idea of whether it might be possible to interpose a milter using OpenDKIM (perhaps zdkimfilter) between Mailman and the outgoing SMTP server (courier-MTA) so that outgoing list posts are appropriately signed.
I know next to nothing about DKIM, but there was a time when I knew next to nothing about almost everything, so I learn what I have to to make things work :) -- Lindsay Haisley | "The only unchanging certainty FMP Computer Services | is the certainty of change" 512-259-1190 | http://www.fmp.com | - Ancient wisdom, many cultures ------------------------------------------------------ Mailman-Users mailing list [email protected] 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
