About
SpamCop analyses unwanted email submitted by users, identifies its apparent source and prepares reports for the relevant service providers. These reports also contribute to spam-filtering systems. The website provides reporting accounts, an IP lookup and guidance for administrators who receive a report or find a server listed.

The SpamCop Blocking List, or SCBL, lists sending IP addresses associated with reported mail. It uses automated reports and user submissions, and listings expire automatically when reports stop. Mail server operators can query the DNS-based list as one input to their filtering system.
SpamCop makes the blocklist available without charge. Its implementation guidance describes the list as aggressive and recommends combining it with an actively maintained allow list, and tagging or diverting messages where appropriate. This matters because the list can affect wanted mail as well as spam. The site links technical guidance, report explanations and community support.
Recipients of a SpamCop report can follow its embedded links to analyse the reported message and use the response options provided.
