What does the "Bi-Directional" setting ensure in Mimecast policies?

The "Bi-Directional" setting within Mimecast policies is designed to apply the policy across both inbound and outbound mail flows. This means that any email communication entering or leaving the organization is subject to the same set of policy rules.

This functionality is essential for maintaining consistent email standards and security protocols, ensuring that all email messages are monitored and managed equally, regardless of their direction. By implementing this type of policy, organizations can better control risks, enforce compliance, and protect against threats such as phishing and malware on both ends of the communication spectrum.

Other options do not capture this dual applicability, focusing instead on limited scopes that do not encompass the full capabilities of the Bi-Directional setting.
