DNS Blackhole Lists or DNSBLs are a way to filter spam by using Domain Name Service (DNS) records as a database of policies relating to either an IP address or domain name, which can be used to decide whether or not to accept (or label) email. Don't use any of these without testing them first and reading any available listing policy.
