Why don't you move _both_ MX receivers to different machines, leaving
your 'highly available' delivery server to serve real users while the
spam fighting happens elsewhere?  Then the check_against_smtp_server
will work against the user base as it should and if one or the other
of the MX gateways has a problem the failover will take care of it.
If you are currently having enough trouble with the primary server
to have noticed it, a plan with a good chance of fixing the problem
should justify the extra box to the suits.
