Hey Ned, 

I found this very useful to test that the RBL was working: 


How do I test my SBL setup? 
	Once you have set up your mail server to use sbl.spamhaus.org (or the preferred zen.spamhaus.org), you can test to see if the SBL blocking is working by sending an email (any email) to: nelson-sbl-test at crynwr.com (you must send the email from the mail server which you wish to test). The   Crynwr   system robot will answer you to tell you if your server is correctly blocking SBL-listed IP addresses or not. 

Just thought I'd throw it out there.
