Secure Messaging allows users to transmit confidential messages to recipients. However the functionality differs depending on if a message is sent to an external or internal recipient.


If sent to an external recipient, the message isn't sent to the recipient's mail server. Instead it is retained by us in our Secure Messaging Portal, and a notification is sent to the recipient. From the notification the recipient can:

  • View the secure message.
  • Send a secure response, if the sender configured this when the secure message was sent.


Internal Secure MessageIf a secure message sent to an internal recipient, the message isn't retained in our Secure Messaging Portal. Instead it is delivered through your mail server. The message is delivered with a banner (see right). The recipient can reply normally via their email application, or securely (if this was configured when the secure message was sent) via:

  • The Secure Messaging Portal
  • A Mimecast end user application.
