I've been keeping tabs on SA's specificity and sensitivity. On ~40k mails, ~3300 spams, adjusting for some exceptional cases (one mailbombing of 300+ items handled with a separate rule), since Feb 1: True positive: 95.5% False negative: 4.5% True negative: 99.82% False positive: 0.18% Damned good tool.
