Spamhaus DBL lookup and removal

Domain Block List: domains seen in spam, phishing, malware and botnet command traffic. Checked against links in the message body and sender domains. Check your domain below, then follow the removal steps if it is listed.

Checks run by DNS only. Nothing is sent from or to your domain.

How to get removed from Spamhaus DBL

Spamhaus DBL removals go through the operator's lookup and removal portal. Fix the cause first, then request removal for the listed address.

  1. 1 Look up the domain on the operator's site and read the listing reason and return code.
  2. 2 Find where the domain appears in unwanted mail: compromised website links, a list bought or scraped, affiliate links, a hacked form that sends mail.
  3. 3 Fix the cause before asking for removal. A list that relists you quickly usually takes longer to remove you the second time.
  4. 4 Open the removal page (https://check.spamhaus.org/), enter the listed domain and follow the confirmation steps (often an email link).
  5. 5 Re-check the domain here after the next zone update to confirm the listing is gone. Monitoring alerts you if it comes back.
