Listed on PSBL? How to get delisted
PSBL (Passive Spam Block List) lists IP addresses that hit its spam traps. It is a low-false-positive list with immediate self-service removal.
Confirm whether your domain and mail servers are listed.
Why PSBL lists a IP
An IP is listed after it sends mail to a PSBL trap address, usually from spam, a compromised host, or scraped and outdated mailing lists.
How to get delisted
- Stop the spam source and clean your lists so trap addresses are no longer mailed.
- Use the PSBL self-service form to remove the IP; removal applies immediately.
- Fix the root cause first: an IP that keeps hitting traps is simply listed again.

Prevent re-listing
Delisting only holds if the cause is fixed. Enforce a DMARC policy, keep SPF and DKIM aligned, secure sending accounts, and monitor for compromise. A clean deliverability report is the best signal that the underlying setup is sound.
Frequently asked questions
How long does PSBL delisting take?
It varies by list. Automatic lists clear within hours once the abuse stops. Manual removals apply as soon as the operator processes the request, provided the root cause is resolved.
Will delisting fix my deliverability?
Removing the listing helps, but receivers also weigh authentication and sending reputation. Pair delisting with a strong SPF, DKIM, and DMARC setup for lasting improvement.
