(Vamsoft ORF is a spam-filter.) Basically uribl.com was returning

"After investigating this further, it seems the affected ORF users
all use Google public DNS servers for the queries (or use such servers
as forwarders in their local DNS configuration)."
Anyone using open recursive DNS servers or their ISP's DNS server for
DNSBL queries is asking for trouble. The listing is to get the
attention of the sender. It's "antisocial".
I have to wonder, if a DNSBL were being operated entirely on a free
basis (rather than a freemium model), might it not be better to take
advantage of the large caches out there rather than having thousands of
individual servers performing the same mundane set of lookups individually?
Obviously this negates the DNSBL's ability to try and pull cash out of
the larger entities, but purely from a resource management point of
view, if someone wants to offer a front-line cache for free, surely that
should reduce load.
