Spamhaus lists are not free for certain uses. If you have exceeded
allowed free use from a single IP address, you may be blocked. See
http://www.spamhaus.org/organization/dnsblusage.html
for usage terms.

BRBL requires preregistration. Similarly, they might block access from
unregistered hosts.
Neither Barracuda nor Spamhaus lookups are likely to work through a
free DNS forwarding service like Google Public DNS or OpenDNS.
Likewise, many ISP nameservers are probably blocked.

FWIW I would disagree with your scoring, based on my statistics. I
would score BRBL higher than Spamcop. The latter has numerous issues
with freemail outbound relays, which could cause false positives. I'm
using all three of the above, but only NJABL of the ones below.
