Hello,
I've just adapted an old script I use with squid to remove unwanted ads to use surbl...
This works as a redirector - this means, each time someone ask for an url matching surbl database, squid will redirect the query to a locally saved web page - e.g. a web page showing the site policy or a simple error message.
For the while, this is a very draft script, but it works fine.
I'll surely improve it and maybe write a C version which shall be much faster for huge domains.
You can get it at :

All feedback is welcome.
Best
Jose-Marcio
