What is 0spam DBL?
0spam is a free, community-run anti-spam project that publishes several DNS blocklists. Its domain list (url.0spam.org) contains domains and URLs seen in spam messages caught by 0spam spam traps. Mail filters such as SpamAssassin and Rspamd can query it to score or reject email that contains a listed domain.
Why domains get listed on 0spam DBL
- Your domain or a link on it appeared in email that hit 0spam spam traps
- A compromised mailbox or contact form on your site sent spam containing your URL
- An affiliate, reseller or marketing partner promoted your domain in unsolicited mail
- Your site hosts a redirect or shortened link that spammers abused
What a listing means for your email
Email that mentions your domain, including your own signatures and links, can be scored as spam or rejected by receivers that use 0spam.
How to get delisted from 0spam DBL
Confirm the listing
Look up your domain on the 0spam website to confirm it is listed on the URL/domain list and note the date it was added.
Find and stop the source
Check outgoing mail logs, web forms, newsletters and partners for anything that sent unsolicited mail containing your domain. Reset passwords on compromised mailboxes and add CAPTCHA to open forms.
Tip: Removal requests made before the cause is fixed are usually denied or the domain is relisted within days.
Submit the removal request
Use the removal option on the 0spam lookup result. Describe briefly what caused the listing and what you changed.
Verify the delisting
Check the lookup again after one to three days, then send a test email containing your domain to a few external mailboxes.

Frequently asked questions
Is 0spam removal free?
Yes. 0spam does not charge for removal requests. Be wary of any third party that claims to sell guaranteed 0spam delisting.
How long does a 0spam listing last?
Listings can expire on their own once no new spam is seen, but submitting a removal request after fixing the cause is usually faster.
