Encryption and Signature for Internet Fax/E-Mail
For security, this machine can apply encryption and/or electronic signatures to the Internet Faxes/e-mails.
Use of encryption and/or electronic signatures helps prevent e-mail spoofing and information leakage.
Encryption and electronic signatures can be used with the following functions:
E-mails sent to a standard address
Internet Faxes/e-mails transmitted with the Email TX Results function
Internet Faxes/e-mails transmitted with the Folder Transfer Result Report function
Internet Faxes/e-mails sent to the destination registered in [Store]
Internet Faxes/e-mails routed to the receivers registered in Personal Boxes
Internet Faxes/e-mails transferred to the destinations registered in Transfer Boxes
Internet Faxes/e-mails forwarded to destinations registered in [Forwarding]
Internet Faxes/e-mails routed with the SMTP reception function
You can configure whether to apply encryption and/or a signature to Internet Faxes/e-mails for each function.
In addition, you need to configure the encryption and signature settings on Web Image Monitor in advance. (Web Image Monitor is a management tool installed on this machine to monitor this machine or configure settings for this machine by using a web browser.)
Encryption
Specify the encryption settings in the Web Image Monitor's Address Book for each destination that you want to send encrypted Internet Fax/e-mail to. If you select [Encrypt All], all e-mails are sent in an encrypted form, regardless of the encryption settings specified individually. The key mark (
) appears on the destination key of a destination set to [Encrypt All].If you have selected multiple destinations including destinations for which encryption has not been configured, e-mail sent to such destinations is not encrypted even if you specify encryption.
Signature
The electronic signature is limited in the following ways, depending on the S/MIME settings on Web Image Monitor.
If [Set Individually] is set:
If you send e-mails from the standby screen, you can set [Signature] in [Security] to apply a signature for each destination.
If you send Internet Faxes/e-mails with other functions, you can set [Signature] in [Security] to apply a signature for each function.
If [Do not Use Signatures] is set:
Even if you press [Security], [Signature] does not appear.
If [Use Signatures] is set:
An electronic signature is attached when you send Internet Fax/e-mail. The [Signature] setting in [Security] cannot be canceled.
For details about e-mail encryption and an electronic signature, see "Configuring S/MIME", Security.
E-mail encryption and electronic signatures are not available with standard transmission to Internet Fax destinations. Encryption is only available for forwarding, routing, or transferring to Internet Fax destinations.
Encrypted e-mail cannot be broadcasted. When specifying multiple destinations, broadcasted documents are sent one by one in the order in which the destinations were specified.
This machine cannot receive e-mails encrypted with S/MIME. When configuring the S/MIME encryption settings, you should confirm that the receiver can receive S/MIME-encrypted e-mail.
For details about how to specify encryption and electronic signature settings, see the following:
If a certificate has expired while transferring e-mail from the server to a destination, the destination might not be able to receive the e-mail. For details about a certificate, see "Configuring S/MIME", Security.
If a certificate has expired while forwarding or routing Internet Faxes or e-mails, an error notification e-mail is sent to the originator or the end receiver.
