Is the DBL included in the Spamhaus Zen DNSBL?
Spamhaus Zen is an IP address DNSBL zone. Zen lists numeric IP address zones only, it does not list domains and does not include the DBL.
The DBL is a purely domain-based zone, and must be queried separately by software capable of extracting domains from email message bodies and headers.
