Works! All you need to do is add the multi.surbl.org ( or
whatever list
you want to use ) to the Host Search order. So that x.com is
looked up as
x.org.multi.surbl.org
This would only work for x.com, not www.x.com, etc. The SURBL servers - correctly - return NXDOMAIN when queried for subdomains of listed domains, rather than treat the listed domains as wildcards.
Also - this generates a lot of unnecessary dns queries for non-listed domains.
I hate to say it.....but... Patrik is right :)
