Hi Matt,

Yes, it does. But SA uses the results of Mail::DKIM heuristically
and a DKIM failure is frequently not a sufficient basis for rejection.
During the (old) DKIM discussions there was a view that the result of
a DKIM verification was to be used as input for policy
decisions. That is similar to the above. This was also discussed on
a SMTP mailing list [1]. There is the following recommendation in RFC 6376:
"Therefore, a Verifier SHOULD NOT treat a message that has one or more
bad signatures and no good signatures differently from a message with
no signature at all."
