Domain Listed on SURBL? Here's How to Clear It
SURBL doesn't list mail servers. It lists domains that show up in the links inside spam, phishing, and malware emails, so when your domain is on it, mail that mentions your domain gets flagged, no matter who sends it.
Examples:
Why Legitimate Sites Get Listed
Often it's a hacked website. Attackers plant phishing pages or malware on a real WordPress or Joomla site, and SURBL lists the domain until it's cleaned up. A hijacked DNS control panel can do the same thing by adding malicious subdomains.
Clean Up, Then Request Removal
For phishing, malware, and hacked-site listings, SURBL wants the site and every machine that uploads to it fully cleaned and secured before you ask. Check your DNS records too. Then look up your domain on SURBL's lookup page and follow the removal form it leads to.
Find Out Before Your Customers' Filters Do
Generator Labs checks your domains against SURBL and 150+ other data sources and alerts you by email, Slack, SMS, or webhook when one gets listed, so a hacked site gets fixed in hours, not weeks. Free for your first host.
