Suspicious Email Submitter

The Suspicious Email Submitter is a discontinued extension for common web browsers and email clients that enables the user to easily submit a suspicious email with all the information necessary to a pre-configured destination for further analysis, such as a MISP instance.

This functionality has now been merged into PhishDetect, whose development you can follow here.

This project is hosted by the Computer Incident Response Center for Civil Society (CiviCERT), representing the needs of the at-risk communities Rapid Response Network member organizations serve. The extension will be built to be easily configurable for use by other organizations and communities both within and beyond these communities.
