Others have given a lot of good things to check for. However, one more thing to check for. Check to see if any of your spam is matching the rule named ALL_TRUSTED. If it is, you must manually declare a trusted_networks because the auto-detection algorithm is getting confused. See: http://wiki.apache.org/spamassassin/TrustPath (Note: The trust path problem exists in SA 2.6x as well, it's just less noticeable. Usually in 2.6x the only side effect is FP's on dialup RBLs like SORBS_DUL.) Also, I'd consider grabbing the bayes rule scores from SA 3.0.3, or just upgrade to 3.0.3 outright. 3.0.3 fixes some scoring issues in 3.0.2 and a few important bugs that 3.0.2 suffers from in terms of accuracy (mostly URI parsing for URIBLs). If you're reluctant to go to 3.0.3, the adjusted scores from 3.0.3's 50_scores.cf are as follows: score BAYES_60 0 0 3.515 1.0 score BAYES_80 0 0 3.608 2.0 score BAYES_95 0 0 3.514 3.0 score BAYES_99 0 0 4.070 3.5 score SPF_FAIL 0 0.001 0 0.875
