I'm not saying that the RBL you mentioned won't be of value, I am saying that we are getting over 1 million connections to each mail server every day. If I query in any order the RBL's I am taking up a lot of CPU, Traffic ( from a bunch of packets not heavy bandwidth ) and then the resources of the RBL's as well. If I simply kill the connection at the firewall I have saved many resources for a multitude of people. While I like the free services many of these people provide, the minimal donations I have given on few occasions doesn't support their paper budget for the year, so I want to use the services efficiently appreciating what they are doing for the community. If you meant to feed the firewall with the ip's in this list, than that of course may be something to consider and test. Joey
