It's also worth mentioning that if someone else's previous advice is/was followed (about changing the MLM From: to a generic list address) there would be no way to killfile someone, filter by name, NOR any sense to long threaded discussions where MUAs do quoting and others copy+paste. In Mailinglists, rfc5322.From: is sacred (and according to RFC 5322 so are Sender and Reply-To, which DMARC conveniently disregard) -Jim P.
