As you can see, the SURBL tests stack up very nicely. I've stopped tracking FPs from the SURBL tests as the overall results of these tests have been very good. I'd like to take the opportunity to thank Jeff and the list creators and maintainers, as well as the DNS hosting providers, for their time and efforts in making this very valuable spam prevention service available to anyone who wishes to use it, it's very much appreciated.

Keep up the good work!
