Spamhaus XBL Blacklist Check & Removal Process

How to check if you are listed in Spamhaus XBL?

How to remove a Domain/IP address from Spamhaus XBL?

  • The XBL is an evidence-based list. If you request removal while your system is still infected or vulnerable, the Spamhaus automated scanners will immediately re-list the IP.
  • Please visit: https://check.spamhaus.org/
  • If the IP is listed on the XBL, click the “Show Details” button. This will show you exactly what type of exploit was detected (e.g., “CBL” or “Exploit”).
  • Follow the provided link to the Removal Form.
  • Provide a valid Email Address (you must have access to this to confirm the request).
  • Explain the specific corrective actions you have taken (e.g., “Secured a compromised web form” or “Updated vulnerable plugins”).
  • Confirm: Check your email for a message from Spamhaus and click the confirmation link to finalize the process.
  • Wait Time: Approved removals typically propagate within minutes, but can take up to 24 hours to reflect across all worldwide mail servers.
