Maybe I'm mistaken, but it appears each end user has to buy the service for their own mail servers, and the ISP isn't allowed to bypass that. For the purpose of the agreements with spamhaus, an ISP customer is probably considered a third party, and making a rbldns server available to them is disclosing spamhaus' secret DNSBL zone information....
In my experience, they're pretty reasonable. I would talk to them (or one of their datafeed sales agents) before assuming that they won't sell you the service you need. R's, John
