You will also want to look at:

      /usr/local/share/spamassassin/5-_scores.cf

There are two ways to use the rbls. You can either raise the score for 
being in the RBL above SA's threshold. Or you can out and out block 
servers in the RBL from your MTA. You probably want to be carefull with 
the latter technique since is transfers onus of the work of delivering 
the mail into the wrong hands.

I just spent 3 hours diagnosing a problem for a client on Friday. It 
turns out that people weren't able to deliver email to him and for the 
past 6 months he's believed that there was some intermittent problem 
with his ISP's mailserver. The actual problem is that his ISP is using 
an overzealous RBL. I found out about this because my delivery server 
was listed in his RBL due to some mistake that happened in 1999 before 
my ISP got the IP address. The practical upshot for my client was that 
until he could find someone who could both see and diagnose the problem 
he just wasn't receiving mail and thus he was loosing business. Nota 
Bene for all users of RBLs.
