Hi Folks,
I'm sure at least some of you have been bitten by the debacle associated
with Yahoo turning on strict DMARC enforcement (particularly any of you
who, like me, manage a list server).
Which leads to a question: Any suggestions for how to validate a DKIM
signature, and apply an Original-Authentication-Results header, at the
MTA level (specifically Postfix)? (And/or, any operational experience
that this is a viable way to address the problem.)
Thanks very much,
Miles Fidelman
