Domain Name System Real-time Black List
DNSRBL is an anti-SPAM system. We publish, via DNS, a list of IP addresses of machines that we know to be either direct SPAM sources or Dial-up (dynamic address) pools which would never be a source of non-SPAM eMail. Some users may choose to use our lists to block or add warnings to email. Neither of these facts directly relate to us; we simply publish a list of known SPAM sites.
