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)
