Not running Brian's version or release of spamassassin, but believe there are 
settings in spamassassin to "test" the various RBL's that you want to and add 
appropriate scores.  As already mentioned (correctly), the problem with that 
approproach is that your server has already accepted the message and now must 
do something with it.  Much better to RBL at the sendmail level (DNSBL) and 
not even accept connections from listed hosts.
