Attaching an Electronic Signature
To attach an electronic signature to sent e-mail, a device certificate must be installed in advance.
It is possible to use either a self-signed certificate created by the machine, or a certificate issued by a
certificate authority.
• To install an S/MIME device certificate, you must first register "Administrator's E-mail Address"in
[System Settings] as the e-mail address for the device certificate. Note that even if you will not be
using S/MIME, you must still specify an e-mail address for the S/MIME device certificate.
Electronic Signature

machine.)
