It's not that hard, much of the time -- they tend to make themselves visible via their poor behavior. As to Spamhaus policy re appliances in general, their terms are on their web site and while you or I or anyone else may not agree with or like their terms, it *is* their service to offer on the terms that they wish. And given that the Zen DNSBL is far-and-away the highest quality DNSBL available, it's probably worth paying for if one finds oneself in a situation where its use is indicated. An easy way around this is not to use an appliance: it's a straightforward exercise for any competent postmaster to build anti-spam defenses that vastly outperform [1] any appliance in an afternoon. Finally, this discussion should really be on spam-l, not nanog. ---Rsk [1] Where performance is measure in terms of acquisition cost, maintenance cost, FP, FN, bandwidth, memory, CPU, resistance to attack, scalability, etc.
