As you note, blocking 95% of all spam will end up with various spam/ham ratios in the inbox, and that depends on the original spam/ham ratio. If 50% of all incoming email was spam (which is about what I see) then blocking 95% of it would get me down to a ratio of (.05*.5) : (.5), which would be 5% spam and 95% ham. But if 95% of the incoming mail is spam, you have (.05 * .95) : (.05), which is very near 1:1. Assuming that it makes it through the filters, there should be a gif of a chart attached showing the percentage of received mail that is spam, vs the incoming spam rate and the blocking rate. Note that even if only 50% of the incoming is spam, and you can block 50% of that, 33% of the arriving mail at the inbox will still be spam! To get the spam arrival rate down under 10% of the arriving mail at the desktop you pretty much need a blocking rate of 95% or better. Loren
