Hmm. It would take MUA changes to be fully effective, but a possibility that comes to mind is to have mailing lists leave the original message absolutely unmodified, but wrap it in a message that comes "from" the mailing list. That way everything about the message is verifiably true.
A list-aware MUA could more or less transparently unwrap such a message. It would probably display some indication that the message came through the ML - the name of the list, unsubscribe mechanism, archive pointers, ML header or footer text, et cetera, and maybe activate alternative "reply" options[*] - but would largely present the message as "from" the original author, *via* the mailing list. Perhaps the wrapper message would look like today's munged ML messages - From: Real Person <mailingl...@example.com> / Reply-To: Real Person <realper...@example2.com> - but a list-aware MUA would largely hide that. Of course there are a million details and getting adoption would be hard. ------------------------------------------------------ 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
