Thanks for sharing this idea and a free list of the relevant
domains.  I agree it's an interesting idea, though we've been
focussed on spammer's URI domains so far, so it's a bit of a

At nearly 500k record we'd definitely want to do this
with rbldnsd.  BIND is already getting pretty slow with lists
approaching 100k records.  For comparison, sbl.spamhaus.org
has about 5k records, xbl has about 1.7 million records,
list.dsbl.org has nearly 4 million records.  multi.surbl.org,
our largest production list has about 45k records.

How does anyone else feel about turning this list of sex sites
into a SURBL?
