John,
I also experienced the exact same thing. The default setup with no bayes
training really let most of my spam through our filters.
I chose to let the auto training of bayes to work and it did well since I get
to see at least 10,000 spams a day. Along with adding additional cf's I have
moved my threshold back towards 5.0. I'm still sitting at 3.5, but will
eventually probably move it to 5.0.
For the newbie thomas, I also watched what spam was getting under my threshold
and then adjusted I'd say about 2 dozen of the individual scores to help bring
the low scoring spam up nearer to 5.0. You'll have to watch which ones you up
though ie: I brought HTML_MESSAGE up too high and started getting a lot of
false positives.
Good Luck
Scott

I'm new too - Initially I settled on a threshhold of 2.4, and this got
most
things with a few false positives. Then I trained my Bayes with 400
spams
and 200-some hams and added most of the rules from
http://www.merchantsoverseas.com/wwwroot/gorilla/sa_rules.htm Now my
threshhold is back up to 5.0 and it's almost perfect for me! Good luck
