Why use DNS Blacklists?
"The rise of spam and other anti-social behavior on the Internet has
led to the creation of shared blacklists and whitelists of IP
addresses or domains. The DNS has become the de-facto standard
method of distributing these blacklists and whitelists."
How do DNS Blacklists Work?
"A Domain Name System-based Blackhole List, Domain Name System Blacklist
(DNSBL) or Real-time Blackhole List (RBL) is a service where with a simple DNS
query mail servers can check whether a sending IP address is on a blacklist of
IP addresses reputed to send email spam. Most mail server software can be
configured to check one or more of such lists - typically rejecting or flagging
messages if it is from a listed site."
