Just ran a quick check of my email logs. The four primary layers of filtering I use (SpamAssassin rule-based, PopFile Bayesian, EarthLink probe-based, and hand-coded rules) are now catching over 700 spams per day, which represents 85% of my total incoming email.
That’s a quarter-million spams per year. For one person. Scary.
Thank goodness my filters, after much training, catch about 99% of the spams, with only occasional false positives. I still can’t imagine the average user going to the trouble I have to make the filters work.
