i recommend assp : http://assp.sourceforge.net/

assp = anti-spam smtp proxy

if installed correctly it will sit in front of your smtp-server,
in my opinion it works awesome, and has lots of options, RBL being one
of them

beware however... make sure you look at all the option and do not just
go with all the default examples in the web-interface
