If it helps, I agree with Chris.  One point to note: Virtual hosters
can't use IP addresses in their URLs, because the web server needs a
http host header to differentiate between all the possible virtual
hosted sites.  However, it really wouldn't be difficult to have the
SURBL URI detection algorithm find dotted quad URLs, and store these in
the SURBL database just like any other domain name...

Agreed. They may be listed, but for mail, not hosting. They use other
IPs to send, and keep the host on their IPs. SOme of the bigger spammers
are saying "Screw SURBL, I've got enough dough to get a new domain for
every run, and it still remains profitible."

To which we have 2 replies:
1) Those registers are going to feel some rath soon from the antispam
2) We gonna mark the IP, you silly little monkeys!

I think the code should be added into the SURBL code. It would need to
be a patch for SA 3.0 as it is prbly too late for it to go in now. But
it should be simple to grab the IP of the 20 random URL domains and
match against SURBL as well. Then they can purchase as many domains as
they like, won't matter a bit.
