As a matter of interest, could you say why?
Because it's unlikely that Mailman was doing the DKIM
verification. I tested Mailman to see how it affected DKIM signatures.
Ah! My use of the term "List Admin" was intended to include the activities
of all the servers etc through which the message passed at that site.
I agree that the A-R was probably added before mailman saw the message,
but it was probably mailman that removed the original (now broken)
signature.
But either way, there is no suspicion that the A-R was added by the
spammer, or any other agent prior to the ML site, so no reason to doubt
the truth of what it attested (except for Conspiracy Theorists who doubt
everything - and the best way to placate Conspiracy Theorists is to give
them the evidence that proves their vivid imaginations are wrong - in this
case by signing the A-R header).
