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.
