but of the 250K total, how many are outbound? 10%? That's really not too much for SAV/RAV. postfix's positive/negative caching for SAV/RAV makes it probably the best implementation. You could set up a separate IMGate for outbound only and do SAV/RAV there. But just IMGate to prevent the spamming from getting out is IMGate SAV/RAV rejects as a symptom of your networks being infected. Len
