Rejecting the mail during the *SMTP* transaction *never* involves any
hosts or addresses mentioned in the message headers.  It is a TCP
protocol-level thing only involving the peers: the sending host and
your receiving host.  It's impossible to involve a third party.

Of course, that was the point Paul was making.
