When a Symantec Encryption Management Server Web Email Protection user composes and sends a message to an Internal user or another Web Email Protection user, the message is not classified with a Sensitivity level of Confidential or Private. Therefore, any reply to that message is not, by default, sent securely.
The very fact that a user chooses to send a Web Email Protection message rather than simply sending the message using their standard email client strongly implies that they want the message to have a Sensitivity level of Confidential or Private.
