Domain Name System Blacklists, also known as DNSBL's or DNS Blacklists, are spam blocking lists that allow a website administrator to block messages from specific systems that have a history of sending spam.
If the maintainer of a DNS Blacklist has in the past received spam of any kind from a specific domain name, that server would be “blacklisted” and all messages sent from it would be either flagged or rejected from all sites that use that specific list.
Here is a list of the major databases that track blacklisted IP addresses.
This list is of DNS-based anti-spam databases.
