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.
Free, no signup. See if SURBL, Spamhaus, URIBL, or other major domain blacklists have you listed.
Examples: 203.0.113.42 or example.com

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.
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.
Generator Labs checks your domains against SURBL and hundreds of other blacklists 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.
No. It lists domains found in message bodies.
It was probably hacked and is hosting content someone else put there. Clean it up, then request removal.
