Anti-spam blacklists are lists of networks or IP addresses suspected of being involved with spam. Many email servers and anti-spam software applications use these lists to block unwanted email with various degrees of success.
They are also commonly known as DNSBLs, DNS blacklists, DNS blocklists or blackhole lists.
