Spam List = .....
in MailScanner.conf. Check in the MailScanner.conf file for the docs on 
this option, and in spam.lists.conf for a list of all the RBL's that 
MailScanner already knows about. You can always add more to it if it 
doesn't contain your favourites already.

Also, SpamAssassin will check loads of RBLs for you too and point-score 
them which may well provide you with better results.

SpamAssassin can and will do that for you. I didn't see the point in 
implementing all of that support when SpamAssassin already does it very 
well anyway.

Seems fair, that's what I do too :-)
