The NTP Project uses the following dynamic DNS-based Black Lists to reduce the amount of spam delivered through our mail server:

  • rbl-plus.mail-abuse.org
  • blackholes.mail-abuse.org
  • zen.spamhaus.org
  • cbl.abuseat.org
  • list.dsbl.org
  • dynablock.njabl.org
  • dnsbl.njabl.org
  • relays.mail-abuse.org
  • nonconfirm.mail-abuse.org

We also maintain internal static black lists of servers or networks that have abused our systems in the past.

If you would like to learn more about what black lists are and how they work, the WikiPedia article on blacklists is an excellent place to start. You can also look up your IP address or your mail server via any of various different services, including http://www.mxtoolbox.com/blacklists.aspx, and http://www.dnsbl.info/advanced.asp, among many others.

See also the main AntiSpam page which describes various standard anti-spam techniques that are used to protect the ntp.org mail system, of which the black lists mentioned here are just one mechanism.

Please contact our Postmaster Services Team if you have any further questions regarding the black lists that are used within the ntp.org mail system.
