Have several incoming gateways.
Have changed the greylisting o the "RECEIVIING" server (main server) not to invoke grey listing... but I still see "Waiting to Deliver" on the Incoming GateWay server. If right-click on the Incoming-Gateway email, it just says pending. The "Knowledge Base" doesn't mention anything else to be set up (but then again, it doesn't mention turning off /setting the greylist filter to off for incoming servers either).
In any other ideas? At any point in time, we have 30-40 emails stuck in queue to be delivered (due to this issue)
