Security Settings to E-mails
This section explains the procedure for applying security (encryption and a signature) to e-mail.
Applying security (encryption and a signature) to e-mail helps prevent spoofing and information leakage.
The S/MIME is used to set security. For details about security settings, consult your network administrator.
If you apply security to an e-mail, an error might occur depending on the file size attached to the e-mail. If such an error occurs, change the resolution or other scan settings, and then send the e-mail again. For details, see "Scan Settings".
Applying security to e-mail can reduce transmission speed.
