This will (again) break any sendmail-based defense against unresolvable
sender domains. I have greylisting in place, and my BIND is configured with
the latest delegation-related directives, but would it be something to
consider, to have MIMEDefang reject a message if the domainname of the
sender resolves to VeriSign's search site? (This would help people who dont
do greylisting and/or dont control their DNS server's configuration.
