Also, if you've specified an unresponsive or slow RBL, that > can hinder your performance quite a bit I had some problems with my nameserver last week ... long story... so I was looking at my RBL list, and thought that I could reduce the overhead of the RBL lookups by adding the IP to my blacklist_ip file... I've got the makings of a script that will find all the new RBL rejects, add them to the blacklist_ip file and then unique them... I would suspect that there could be 10's of thousands of IPs in this file - eventually - but over time could really have an impact on performance (increase my server load, but decrease network traffic) I suppose that it could be considered polite to do this to the RBL servers by reducing their overhead as well.
I belive (but not 100% sure) that I have a cacheing nameserver. I'm using the default that plesk gives me (named), but I haven't modified it myself. Is there anything simple I can do to check or configure? I'm technical, but never played with named, so don't really have a clue on where to start looking .... I'm using 4 RBL's - not too many, but not too little either. As far as I can tell, they are responsive, but I don't track them... I guess my main worry is: what happens if there are 10,000 IP's or 20,000 IP's in my blacklist_ip file? does my server start smoking?
