 That is the sender suggesting how I should handle the message on a failure.
I already consider the reputation of the sending domain/ip. If I was
now going to have to start considering the reputations of signing
domains (if they are seperate) I certainly would not leave it up to
the sender to tell me how to do it... unless.. the policy list is
_always_ more restrictive.
