What Is The IBM DNS Blacklist?

The IBM DNS Blacklist is a blacklist that compiles IP Addresses that have been determined to be sources of spam.  If you are listed on the IBM DNS Blacklist, you have been flagged for sending a significant amount of spam emails by the Proventia Mail Security System or the Lotus Protector for Mail Security Systems.  Some users have complained that the IBM DNS Blacklist is extremely sensitive in the way of adding and removing users extremely frequently.

How Do I Find Out If I Am On The IBM DNS Blacklist?

If you received a message that your IP Address is on the IBM DNS Blacklist, you have set off the signals of sending too much spam to filters that alerted the Security System in place.  Or worse, your clients receive a kickback message after answering your email that their message is undeliverable because you are on a blacklist… (yikes!)  Check here to see if you are listed.  

How Can I Remove Myself From The IBM DNS Blacklist?

Follow this link to be removed from the IBM DNS Blacklist.  

In order to fix this issue you’ll need to:

  • Stop sending spam emails that will trigger the security systems
  • Take a break from sending large amounts of emails (regardless if they are spammy or not)
  • Reach out to the organization and request to be removed from their blacklist
  • If you are guilty of actually sending those spam emails, you will remain on the blacklist until your spamming activity has halted
  • If you did not send the spam emails, plead your case in full detail and explain the security issue
  • Alway remember to check the security of your computer.  If you are on a blacklist and did not perform spam-like activity, you may have a virus.

How do I reduce my risk of getting onto the IBM DNS Blacklist?

The best way to avoid getting listed on a blacklist is to engage in proper email practices such as...

  • Verify all email addresses before attempting outreach
  • Avoid sending unnecessary emails
  • Avoid the use of spam words within your email drafts
  • Keep your sending volume to a minimum (30-50 a day if your inbox has been warmed up with us for at least 30 days)
