I should clarify that I mean: use the Spamhaus data with programs
that resolve the URI domains into IP addresses, or check their
name server IPs, then check those IP address against Spamhaus.

uridnsbl in SpamAssassin 3.0 does the nameserver check against
SBL.  Don't know if there are programs that check the web site
IPs against SBL, but probably there are.   Does uridnsbl *only*
check name servers?
