See the Spamhaus FAQ page, and in particular note the following response:
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.
Configure MailMarshal/SEG to use a local DNS server.
