OutlookDSD - A simple add-in for Outlook that shows the DKIM, SPF and DMARC status of an email message in the ribbon.

About & Why?

Outlook doesn't alert you when an email has failed DKIM, SPF or DMARC validation. This could create security risks by allowing users to fall victim to phishing or other attacks.

OutlookDSD adds visual indicators displaying the validation results of the DKIM, SPF and DMARC status of received emails, and warning users if a message fails any security validation.
