What is a consequence of having a Blocked Senders Policy?

Having a Blocked Senders Policy can indeed be overridden by higher specificity policies. This feature allows for nuanced control over email filtering by enabling administrators to create more targeted regulations that can take precedence over broader policies, including those that block certain senders. For instance, if a user is part of a group that allows communication with specific senders whom the Blocked Senders Policy typically restricts, the more specific policy can allow their emails through.

This capability is crucial for maintaining effective communication while still ensuring that harmful or unwanted messages are filtered out, thereby effectively balancing security and usability within an organization's email system. It highlights the flexibility of the email security framework, which can adapt to varying needs and situations while preserving the main intent of the blocked senders policy.
