Note that ZEN is an NS zone, not a host. You can not resolve ZEN to a host/IP. http://www.spamhaus.org/faq/answers.lasso?section=DNSBL%20Usage#122 You should however be able to resolve the test address: 2.0.0.127.zen.spamhaus.org If you can't resolve the test address, it may be that the DNS server you are using has exceeded Spamhaus's free usage limit. In that case, running your own NS resolver will normally solve that (unless your actual mail traffic is higher than the free use limits). > but google public dns does. Google public DNS is probably giving you a custom (bad) answer in place of 'host not found'. > ins2:~ root# nslookup zen.spamhaus.com > Non-authoritative answer: > Name: zen.spamhaus.com > Address: 208.87.33.151 spamhaus.com != spamhaus.org. The domain squatter who operates spamhaus.com has a wildcard pointing *.spamhaus.com at his adverts server.
