The W3C mailing list manager (MLM) is apparently configured to do
rfc5322.from field re-writing which seems to ameliorate the DMARC-MLM
issues (in my experience, at least), and it would be helpful if the IETF
would take similar measures.
Due to the volume of mail from IETF lists, I have a bunch of procmail
rules to sort them that would break if the lists put the list address
on the From: line. And, of course, then you can't reply to the author.
I doubt that I'm the only one in this situation.
There are DMARC workarounds that are more work but suck less.
