Cisco Cisco Email Security Appliance C170 사용자 가이드

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.

The key server uses an HTML or text notification based on the recipient’s email application. You 
must configure notifications for both.

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.

Enter a subject header for encryption failure notifications. The appliance sends a notification if the 
encryption process times out.

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.

Submit and commit your changes.

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.

The Cisco IronPort Email Encryption Settings page displays the current versions of the PXE engine and 
the Domain Mappings file used by your appliance. In previous versions of AsyncOS, you had to update 
AsyncOS in order to update the PXE engine. Now, you can use the Security Services > Service Updates 
page (or the 

updateconfig

 command in the CLI) to configure the Cisco IronPort appliance to 

automatically update the PXE engine. For more information, see 

You can also manually update the engine using the Update Now button of the PXE Engine Updates 
section of IronPort Email Encryption Settings page (or the 

encryptionupdate

 command in the CLI).

After you create an encryption profile, you need to create an outgoing content filter that determines 
which email messages should be encrypted. The content filter scans outgoing email and determines if 
the message matches the conditions specified. Once the content filter determines a message matches the 
condition, the Cisco IronPort Email Security appliance encrypts the message and sends the generated 
key to the key server. It uses settings specified in the encryption profile to determine the key server to 
use and other encryption settings.
