Hello all,

Have been seeing a lot more spam getting through and have also recently
had to start a new bayes database. Below is the scores from an obvious
piece of spam. Looking at the scores assigned, I would think these
should have been higher. The total score here was 4.8 and my threshold
is 5 for spam and 10 for high scoring spam. Seems to me there is an
issue somewhere in my setup. This is a Linus RH 9 box and a CentOS box
for my secondary. My question is, (and I have looked through the
archives and did not find much that helped but maybe I searched with the
wrong keywords?) how can I A:) make spamassassin assign proper scores to
obvious spam, B:) train the bayes database ( cannot assign users ham and
spam folders .... it just would not work with my users). Any other
suggestions would also be welcomed.
