BTW, I (think I) understand how the whole thing works, but... isn't it possible to change SpamCopURI to resolve the names at a specific machine ip/port, instead of changing the DNS setup? Wouldn't this be easier and safer?
[]s!
I personally think its easier to setup the DNS. This is also necessary for the more general case. If you're running a high volume mail server and using local copies of other blocking lists, they will also need to be set up like surbl through your DNS.
I'm not aware of other software (such as MTAs) which will allow you to configure ip/port for dnsbl lookups.
If you're running bind as the main DNS, then you can just configure it to forward requests for the surbl zone to your local copy on whatever ip/port you chose.
