What is the Spamhaus Project? 

The Spamhaus Project is an international non-profit organization that tracks spam and related cyber threats such as phishing, malware, and botnets. With this, Spamhaus provides real-time actionable and highly accurate threat intelligence to the Internet’s major networks, companies, and security vendors, and works with law enforcement agencies to identify and hunt for sources of spam and malware globally.

  • businesses of all sizes
  • government departments;
  • civil society organizations. 

Listing criteria for Spamhaus vary widely. If you have to summarize it, like all other IP-based DNS blacklists, the list comes up when spam is seen or reported. However, since Spamhaus maintains a total of 6 different blacklists, significant granular control is possible, allowing spam to be sorted according to the needs of the end-user. Spamhaus recently added a Domain Block List (DBL) to its traditional IP-based blacklist, which will list domains that have been used in spam.
