Configuring S/MIME
By registering a user certificate in the Address Book, you can send e-mail that is encrypted with a public
key which prevents its content from being altered during transmission. You can also prevent sender
impersonation (spoofing) by installing a device certificate on the machine, and attaching an electronic
signature created with a private key. You can apply these functions separately or, for stronger security,
together.
To send encrypted e-mail, both the sender (this machine) and the receiver must support S/MIME.
Compatible mailer applications
The S/MIME function can be used with the following applications:
• Microsoft Outlook 98 and later
• Microsoft Outlook Express 5.5 and later
• Thunderbird 3.1.7 and later
• Lotus Notes R5 and later
• Windows Live Mail 2009 and later
• To use S/MIME, you must first specify [Administrator's E-mail Address] in [System Settings].
• If an electronic signature is specified for an e-mail, the administrator's address appears in the
"From" field and the address of the user specified as "sender" appears in the "Reply To" field.
• When sending e-mail to users that support S/MIME and users that do not support S/MIME at the
same time, the e-mail is separated into encrypted and unencrypted groups and then sent.
• When using S/MIME, the e-mail size is larger than normal.
• For details about using S/MIME with the scanner function, see "Security Settings to E-mails", Scan.
• For details about using S/MIME with the fax function, see "Encryption and Signature for Internet
Fax/E-mail", Fax.
E-mail Encryption
To send encrypted e-mail using S/MIME, the user certificate must first be prepared using Web Image
Monitor and registered in the Address Book by the user administrator. Registering the certificate in the
Address Book specifies each user's public key. After installing the certificate, specify the encryption
algorithm using Web Image Monitor. The network administrator can specify the algorithm.
