Some RBL's offer to download all the data in their database awhole, mostly 
via rsync; then you can install these zone files directly to your local 
DNS server and can retrieve the data without any remote DNS lookups.


If this really makes sense for you highly depend on the amount of requests 
your configuration makes.

[Mimedefang] building a caching dns to keep uri blacklist lookups

[Stephen Ford]

I just got done talking with an engineer from a spam
filter company that mentioned there is a way for uri's
to be saved to the local caching dns so the next
lookup will be local.  I just thought having a local
dns would do that.  Did I miss something in my setup? 
If so, what do I need to change?

Thanks again for everyone's help on getting this up
and running.
