Hmm... here's something interesting...
grep -r autolearn pgsql/ | grep -v 'Binary file' | sed -e
's/.*autolearn=\([^ ]*\).*/\1/' | sort | uniq -c
2010 ham
198 no
17 unavailable
So a big chunk of [EMAIL PROTECTED] email is being learned as ham.
Looking further, I see...
X-Spam-Status: No, score=-2.6 required=5.0 tests=BAYES_00 autolearn=ham
version=3.1.0
ISTM that having the thresholds setup so that BAYES_00 scores low enough
to autolearn is a BadThing, as it creates a positive feedback loop. :)
I've added bayes_auto_learn_threshold_nonspam -2.6 to my personal
config; we'll see if that helps.
