What does 'flow control' manage in the context of Mimecast's email security?

In the context of Mimecast's email security, flow control specifically manages the flow of emails to ensure uninterrupted service. This means that during various operational challenges, such as system outages, high traffic periods, or other disruptions, flow control helps maintain the continuity of email delivery. It effectively queues and manages incoming and outgoing emails to avoid data loss, ensuring users can continue to send and receive messages without interruption.

This functionality is crucial because it provides a seamless experience for users while safeguarding against potential email delivery failures. By maintaining the flow of emails, Mimecast ensures that even under strain, the email service remains stable and reliable. This is essential for organizations that depend heavily on email for communication and operations.
