Because we are NOT allowing outbound mail through this filtering cluster
- it only accepts mail inbound to our 400 mail domains, so no relay
check is required, only a check of the recipients. Any recipient not on
our mail domains gets a relay denied response.

Why aren't you using the access.db? Sendmail will consult this, and
reject the message if necessary without ever needing to send data to
a milter. Doing IP/domain based blacklisting in MIMEDefang isn't
terribly efficient -- although it has other benefits (keeping the data
in external databases, for example).
