Encrypting an E-mail and Adding a Digital Signature (S/MIME)


S/MIME is one of the E-mail encryption schemes. Using S/MIME encrypts an E-mail sent from this machine, preventing a interception by third parties during transmission. Adding a digital signature to an E-mail provides assurance regarding the authenticity of the sender, and certifies that no data has been falsified.

Operations required to use this function (for the administrator)

Enable the S/MIME mode. To encrypt an E-mail, register the encryption certificate in the E-mail address.

How to configure the setting is explained using Web Connection. For details, refer to Here.
