For anyone who's working on the list management BCP:
I sign all my outgoing mail, and I have a feedback loop set up with
Yahoo, which being very modern and advanced keys on signatures, not IP
addresses. A few days ago I sent some messages to one of the Freebsd
mailing lists. Today some Yahoo user who subscribes to that list hit
the spam button. Freebsd's list software (Mailman, I think) doesn't
sign, and doesn't strip any headers. So what happened? Yahoo saw my
signature and sent the reports to me, which was of course useless
since I don't run the list.
This is not a hypothetical problem--all of my recent Yahoo FBL reports
If I understand correctly, you established a private arrangement with Yahoo.
Yahoo chooses to create a unique interpretation for the presence of a DKIM
signature, which treats it as an override to the MailFrom. And from this,
you
are asserting a new, general rule about DKIM handling?
That is exactly my reaction: the way to deal with broken software is to
fixate and blame the pointer to the broken software? Madness lies that way.
