Welcome to DKIM Reputation!

The DKIM Reputation Project’s aim is to improve spam filtering based on DKIM signed emails. Therefore we provide the following free and open services:

  • DKIM Reputation database, provided as a DNS reputation list
  • DKIM signature verification and monitoring
  • DKIM Reputation query
  • We also propagate the spread of authenticated email with the Sender Authentication Initiative!

    Message Face

    As a practical application for email sender authentication we introduced a project called ‘Message Faces’ in the past for a better visual recognition of the people sending email to you. In our opinion such user-centric applications should favor the adaption of sender authentication. The project was terminated because of a lack of funding but may be revived in a new context.
