Regardless of details, applying some sort of remediation to
ietf.org/mailman is becoming more pressing IMV -- I am noticing that
email, sent from pingidentity.com (p=quarantine; pct=100;) via IETF
mailing lists, is not being delivered to my paypal.com inbox at all.
Also, the same is occurring for some email from microsoft.com
(p=quarantine; pct=30;). The same is true for email I might send via
my @paypal.com persona.
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.
There was a message [1] from Russ Housley on this thread in which he
mentioned that: "Mailman has an option we can enable to force
DMARC-spoofing sender rewriting of all outgoing Mailman email. If we
enable that option, the From: field rewriting and could be disruptive
in unknown ways". It was also mentioned that "SPF/DMARC are taken
into account" for the scoring of incoming email to ietf.org.
