Configure VIPRE Outbound Authentication Token

The Outbound Token is a unique token added to the email header that is generated automatically and adds an additional layer of security by:

• Uniquely identifying and authenticating legitimate outbound traffic from your cloud-based email solution
• Acting as a preventative measure, ensuring only authenticated and authorized traffic is processed
• Mitigating the risk of being blocked/added to a denylist by major email providers by providing a reliable method for distinguishing legitimate traffic from potential malicious activities
