DNS Blacklists have a rather long history in web terms, with the first one being created in 1997. Called the RBL, its purpose was to block spam email and to educate Internet service providers and other websites about spam and its related problems. Although modern DNS Blacklists are rarely used as educational tools, their function as an email blocker and filter still serves as their primary purpose to this day.

In fact, almost all of today's email servers support at least one DNSBL in order to reduce the amount of junk mail clients using their service receive. The three basic components that make up a DNS Blacklist - a domain name to host it under, a server to host that domain, and a list of addresses to publish to the list - also haven't changed from the time when the RBL was first created to today.

DNSBL is a Domain Name Blacklist. There are dozens of DNSBLs online, all of which use a wide variety of criteria for listing and delisting addresses. Spam filters utilize various DNSBLs to verify that the incoming emails do not originate from blacklisted sites. DNSBLs are generally the first line of defense against spam.

SURBLs (no longer an acronym) are generally the second line of defense but not all spam filters are capable of using them. SURBLs are blacklists of websites that have been noted for appearing in unsolicited emails. Spam filters that can utilize the SURBLs will scan the body text of emails and extract any website addresses and check them against the blacklists. If an address is found, the message will be flagged as spam and handled accordingly.
