There seem to be a number of replies that CC both the old and new list address, resulting in multiple copies of lots of messages. I can filter them at my end, but it'd be better to address that at the list server.
There's no easy way to filter this out in mailman3 as it doesn't have a way to tag a given message ID as already processed. As the archiver (hyperkitty) uses message-id as the primary key, it will only appear once there. it does appear in the digests however as that's essentially a one off mbox container which is emptied into the periodic digests.
Well... maybe just stop the old address from forwarding to the list? Set up an autoresponder that tells people to use the new address? -- Chris Adams <cma@cmadams.net>
