S/MIME Communication Setting Function

2.12 S/MIME Communication Setting Function
When access to the machine by the administrator of the machine through the Administrator Settings is au-
thenticated, the machine enables the setting of encryption of text of e-mail transmitted and received between
the PC and the machine.
NOTICE
To send S/MIME communications, it becomes necessary to register the certificate at the destination. Set
1024 bits or more for the key length of the RSA public key for the certificate of each destination.
Do not use any invalid certificate, as an increased risk results of data to be protected being tampered with or
leaked.
