Is there any info on how to enable/disable/write my own rules? So to see if an ip or hostname is in the RBL it would make a request to the RBL servers on port 53 just like DNS queries? I have my firewall setup to only allow DNS queries to go out to my DNS servers. If spamassassin tries to query another DNS server, it will fail, thats why I need to know which servers I need to enable DNS access to. Thanks, Dhaval
