You can only apply statistics if you know a "ground truth" about what is arriving ... and then you can examine your processing to see how efficient it is. Unfortunately we don't know such a ground truth about incoming spam levels (in fact there's little agreement as to how much spam there is except that it's somewhere between 60 and 95 percent of incoming email) You can create your own ground truth by labelling all the email you see (or getting your users to do it for you) -- as already suggested. You might benchmark your processing against one of the handful of corpuses that exist (where someone else has labelled all the traffic), but these corpuses age very quickly because, as we know, spam is constantly evolving to evade our blocks :( - -- richard Richard Clayton They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.
