Which mail flow paths are affected by the Secure Delivery Policy?

The Secure Delivery Policy specifically influences the mail flow pathways involving Mimecast's email security services. In this context, the correct answer highlights the routes that email takes when moving into and out of your organization via Mimecast.

When considering the mail flow paths, the correct option emphasizes that the Secure Delivery Policy has a defined impact on inbound emails from Mimecast to your organization, as well as outbound emails from Mimecast to external recipients. This ensures that the policies for security, compliance, and filtering are actively applied to all messages entering the organization from Mimecast, improving protection against threats and ensuring that outgoing messages adhere to the organization's standards before they reach recipients outside the organization.

Other options may suggest broader or different scopes of mail flow that are not directly related to the specific impact of the Secure Delivery Policy in relation to Mimecast. For instance, while inbound from any source and outbound to the Internet might seem plausible, it lacks specificity regarding the role of Mimecast in those transactions. Thus, the focus on Mimecast as both the source of inbound traffic and the point of exit for outbound traffic makes the selected option the most accurate representation of the Secure Delivery Policy’s influence on mail flow.
