Domain Listed on URIBL? Here's What It Means
URIBL lists domains that appear in spam messages, and spam filters use it to mark any mail that links to them. If your domain is listed, your own newsletters and even your customers' replies can get flagged.
Examples:
Black, Grey, or Red?
| List | What It Means | What to Do |
|---|---|---|
| Black | Domains owned and used by spammers. | Request removal once you've dealt with the cause. |
| Grey | Domains in bulk mail that may be legitimate, including some ESP customers. | Clean up your list practices, then request removal. |
| Red | Young or unfamiliar domains showing up in mail, flagged automatically. | Automated; request removal if it's wrong. |
Requesting Removal
Create a free account at admin.uribl.com, look up your domain, and submit a delisting request through the form. URIBL doesn't answer delisting requests by email, and it won't explain why a domain was listed. If the lookup shows a SURBL listing, that's a different list: take it to SURBL.
A Quick Sanity Check
If URIBL shows 127.0.0.1 for your domain, that isn't a listing. It means your DNS resolver was refused, which happens with public resolvers like Google Public DNS.
Keep Your Domain Clean
Generator Labs checks your domains against URIBL and 150+ other data sources and alerts you by email, Slack, SMS, or webhook when one gets listed. Free for your first host.
