Man, this really rox!
I've fixed my setup of SpamAssassin here and configured it as a content_filter on Postfix. The performance improved a lot.
Today, it got a 41 points SPAM. There were 26 rules applied and one of them (FREQ_SPAM_PHRASE) had 133 lines of words (I think that there are listed all of the words that are checked) with 17 hits.
If my guess about the every word checked listing is correct, I would suggest that only the words that matched be listed there. It would: save space on the message and show us exactly which words toggled the spam check.
SpamAssassin rul3z, d00d!
