How does Mimecast treat emails that are subject to conflicting policies?

Mimecast addresses conflicting email policies by utilizing the most restrictive policy available. This approach is designed to enhance security and compliance by ensuring that the strictest measures are applied when there is ambiguity or conflict in policy definitions. By implementing the most stringent rules, Mimecast aims to minimize risk, thereby safeguarding against potential security threats or breaches.

Following this method, organizations can maintain a higher level of control over their email environment while also ensuring that any regulatory requirements are met effectively. It ensures that no policies lax enough to risk sensitive data are allowed to override more robust protective measures.

Other choices may suggest alternative methods of addressing conflicting policies, such as blocking all emails or following timestamps, but these do not align with Mimecast's focus on minimizing risk through the implementation of the strictest available guidelines.
