Listed on GBUdb Truncate? How to get delisted
GBUdb Truncate is a low-false-positive list of IP addresses observed sending nothing but spam, so a listing is a strong and reliable signal.
Confirm whether your domain and mail servers are listed.
Why GBUdb Truncate lists a IP
An IP is listed when GBUdb’s statistics show it sends essentially only spam, typically a compromised host, a misconfigured mailer, or a genuinely abusive sender.
How to get delisted
- Stop the spam at the source: secure the host or account, fix the mailer, and close any open relay.
- Truncate is self-correcting. As legitimate mail is observed and the reputation recovers, the listing clears automatically.
- Focus on sustained clean sending; there is no form to submit, so improving behaviour is the delisting.

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 GBUdb Truncate 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.
