Select [Digital ID] to display the screen for selecting destinations. The screen
for selecting an address displays a list of E-mail addresses with registered dig-
ital IDs for S/MIME sending. Specify a digital ID to be used for encryption by
selecting an E-mail address.

Specification of the digital ID is independent of specification of an address;
therefore, you need to specify an address separately.

add a digital signature.
For details on registering a device certificate in the MFP, refer to the "User's
Guide [Network Administrator]".
Select an encryption level. To encrypt a document using a digital ID, you can-
