The re-injection service for filtered mail must be a different IP:port
pair than your MX service.
The spam-filtering service should support XFORWARD, or else apply IP
reputation to the IP address parsed out of the top-most Received header,
when receiving mail indirectly via a set of known forwarders (such your
test configuration). Your transport needs to enable sending XFORWARD
data if the service supports this.
