John, does just deleting ALL mail from the server count :-) That's 100% blocking. It seems that's what almost needs to be done.

(White lists do not count, that circumvents the issue.) With 95% spam blocked, as FP rate of 1% is extremely hard to get. Target is less than 2% held or diverted/rerouted. (Deletion rate of ½ of 1% or less FP is targeted.) Of course, your mileage may very. But overall, that is what is typical!
