Our ISP, Covad, is periodically claiming that we have excessive DNS requests and is threatening to turn off our service. It's primarily due to SA, I think. Looked around for answers, and already set a bunch of the BL checks to 0.0 to turn off the rules. Any idea how to further prevent the excessive DNS requests?
Put your own caching DNS on your mail server, so you're not always banging Covad's DNS. Your spam checks will run a lot faster, too.
