Can you clarify, are your lists intended to be sender domain
lists or message body URI lists:


> What is rhs.mailpolice.com?
> MailPoliceTM maintains a domain-based list of domains which
> have been (ab)used to send spam to our customers. There are
> currently several domain-based lists: one which lists bulk mail
> senders and unsolicited advertisers; pornographic e-mailers and
> websites; reverse DNS hostnames of dynamic Internet
> connections; websites and IP's hosting fraudulant or phishing
> content; legitimate e-mail marketers and opt-in advertisers;
> and domains used by webmail providers.

It sounds from the description that your RHS lists are sender
domains as opposed to message body URI domains as we use
with SURBLs.

That said, I can see how Bill may have found some overlap with
message body URIs.
