Well, I've gotten as far as figuring out that you're SUPPOSED to be able to do a simple namespace lookup with the servers, and the response should give you your answer. Thus, if I wanted to check IP 80.22.221.70, my understanding is that I should shell out to "nslookup 70.221.33.80.sbl-xbl.spamhaus.org" and nab the response. However, when I attempt this, I always get the same thing in response: "Can't find server name for address 10.0.0.1" which is our gateway. Am I doing something wrong, or does this simply not work if my DNS is going through a NAT'd gateway?

The best you might get would be the sendmail docs, because it is sendmail's built-in IP query format that most blacklists support. As for a list of public servers, take a look at the rules in SA's 20_dnsbl_tests.cf for a list of good ones. If you want a more comprehensive list, check the "spam database lookup" on www.dnsstuff.com.
