how to verify RPZ with a 'known bad' domain from 3rd party zone file?

[pgbind9 at ml1.net]

Hi,

I've bind 9.9.2p1 setup to use the RPZ zone provided by spamhaus.  Zone
transfer is apparently working as it should.

I'd like to verify that RPX redirection is actually working for a "known
bad", real domain.

(1) How/where do you extract a bad domain name from the axfr'd RPZ zone
file?  It's not in what appears to be human-readable form.

(2) Once you have that domain, I assume (?) entering it into a browser
should result in a browser redirect to 127.0.0.1 (?)?  In which DNS/bind
log category do I look for evidence of that RPZ-redirection?  In the
query log?

Thanks
