A DNS Blacklist (DNSBL), is a means by which an Internet website can publish a blacklist of IP addresses or hostnames. The technology is built on top of the Internet Domain Name System, or DNS which can be easily queried by computer programs on the Internet. DNS Blacklists (DNSBL) are mainly used to publish lists of addresses linked to spamming. Most mail transport agent (mail server) software can be configured to reject or flag messages which have been sent from a website listed on one or more such blacklists. See the DNSBL page in Wikipedia for more info on DNSBL.
