Must emails directed to a customer's organization pass through Mimecast first?

Emails directed to a customer's organization do not always have to pass through Mimecast first. Organizations can configure their email systems to have the option to bypass Mimecast for various reasons, such as reducing latency or when they have internal policies that require emails to be handled directly by their servers. Additionally, there may be scenarios where customers have specific setups, such as a direct connection to their mail servers for certain types of communications or internal processes, allowing emails to be sent directly without going through the Mimecast filtering and security services. This flexibility is crucial for organizations that may need to ensure that certain emails or types of communications are handled promptly or according to specific protocols.
