Of course I'm running a caching server...my thought was to run a single cacheing server for all of our mailservers to maximize the value of the cache. What I'm saying is if I ran a caching server on each of our individual filter boxes, our volume would appear to be much less unless they aggregated usage by netblock. I suspect many of the "heavy hitters" do this. Andy --- Andy Dills Xecunet, Inc. www.xecu.net 301-682-9972 ---
