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."

How does Corner Bowl do it?

Scans Email Blacklists at the frequency you define.
