Encrypting Messages using the Email Security Appliance
• To enable secure message forwarding feature, check the Enable Secure Message Forwarding
check box.
Step 13 (Optional) If you have selected Cisco Registered Envelope Service and this service supports localization
of envelopes, enable localization of envelopes. In Notification Settings section, check the Use Localized
Envelope check box.
Note If you enable localization of envelopes, you cannot select encrypted message HTML or text
notification.
If you want to set the default locale of the envelope, see Configuring the Default Locale of the Envelope,
page 18-7.
Step 14 Select the HTML and text notification templates.
Note The key server uses an HTML or text notification based on the recipient’s email application. You
must configure notifications for both.
Do the following:
a. Select an HTML notification template. Choose from HTML notifications you configured in text
resources. If you did not configure a template, the system uses the default template.
b. Select a text notification template. Choose from text notifications you configured in text resources.
If you did not configure a template, the system uses the default template.
Note These options are unavailable if you use localized envelopes.
Step 15 Enter a subject header for encryption failure notifications. The appliance sends a notification if the
encryption process times out.
Step 16 Select an encryption failure notification template for the message body. Choose from an encryption
failure notification template you configured in text resources. If you did not configure a template, the
system uses the default template.
Step 17 Submit and commit your changes.
Step 18 If you use Cisco Registered Envelope Service, you must take the additional step of provisioning your
appliance. Provisioning the appliance registers the encryption profile with the hosted key service. To
provision the appliance, click the Provision button for the encryption profile you want to register.
Configuring the Default Locale of the Envelope
The default locale of the envelope is English. If you have selected Cisco Registered Envelope Service
and this service supports localization of envelopes, you can change the locale of the envelope to any one
of the following:
• English
• French
• German
