I am writing to propose a new feature for the RUA report interface, specifically within the Per Sending Source view. We believe that adding a toggle function to mark a Sender ID as "Forwarded" would greatly enhance the usability and accuracy of our email analysis process.

Currently, we analyze RUA reports using the Per Sending Source view to determine whether the sending platform has a contractual agreement with us. Platforms without an agreement typically show DKIM passing but SPF failing. However, we do not automatically classify an SPF failure as a forwarding issue without thorough verification.

To streamline this verification process, it would be beneficial to have a toggle option that, when enabled, categorizes the Sender ID as "Forwarded." This feature would allow us to clearly identify and manage forwarded platforms within the Forwarded view.

We believe that this enhancement will significantly improve our efficiency and accuracy in handling email reports.

Thank you for considering this feature request. We look forward to your positive response.
