Listed on Spamhaus DBL? How to get delisted
Spamhaus DBL is a domain blacklist: it lists domains found in spam, phishing, and malware campaigns, rather than IP addresses.
Confirm whether your domain and mail servers are listed.
Why Spamhaus DBL lists a domain
Domain listings come from the domain appearing in spam messages, hosting malicious content, or being newly registered and used abusively.
How to get delisted
- Confirm the listing and its category on the Spamhaus lookup page.
- Remove any abusive content, secure the site, and stop sending or linking the domain in spam.
- Request delisting through the Spamhaus removal form once the domain is clean.

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 Spamhaus DBL 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.
