1) FAQ: http://wiki.apache.org/spamassassin/HowScoresAreAssigned In this case, the likelihood is that there are multiple RAZOR* rules which work together, i.e.: RAZOR2_CHECK + RAZOR2_CF_RANGE_51_100 =~ 1.8 2) Razor is not even close to being clean of FPs. Here's the results from the 3.0 score generation run (available in the standard tarball's rules directory): 56.104 83.9836 1.8417 0.979 0.37 1.49 RAZOR2_CF_RANGE_51_100 55.815 83.4460 2.0359 0.976 0.36 0.15 RAZOR2_CHECK 0.221 0.2367 0.1907 0.554 0.19 0.10 RAZOR2_CF_RANGE_11_50 Which basically says that while RAZOR2_CHECK hits 83.4% of spam, it also hits 2.0% of ham which is an incredibly high number. 3) If you want to increase the score, that's up to you. -- Randomly Generated Tagline: "You can see I'm having a good time with this...
