Then stop using google dns or other dns servers that block dns request to rbl servers. Source : https://www.spamhaus.org/faq/section/DNSBL%20Usage
Check what DNS resolvers you are using: If you are using a free "open DNS resolver" service such as the Google Public DNS or large cloud/outsourced public DNS servers, such as Level3's or Verizon's, to resolve your DNSBL requests, in most cases you will receive a "not listed" (NXDOMAIN) reply from Spamhaus' public DNSBL servers. We recommend using your own DNS servers when doing DNSBL queries to Spamhaus. I no lame servers in my bind logs. The set below is running over 1 year now, without any problems.
