Look at it from Postini's lawyers viewpoint: If your DNS' MX record points to
a mail server that does spam/virus filtering, and that mail server is NOT the
mail server that ultimately saves the message to /var/spool/mail/whoever (or
equivalent mail store), then you are in violation of their patent because you
have used DNS to specify a filtering system that then delivers its filtered
mail to the ultimate target using the target system's DNS MX record.
