Cisco Cisco Email Security Appliance C160 Mode D'Emploi

To send a Registered Envelope with envelope key caching enabled, insert the 
following header into the message:

X-PostX-Remember-Envelope-Key-Checkbox: true

The “Remember the password for this envelope” check box is displayed on the 
Registered Envelope.

To send a Registered Envelope that is JavaScript-free, insert the following header 
into the message:

X-PostX-Use-Script: false

When the recipient opens the securedoc.html attachment, the Registered Envelope 
is displayed with an Open Online link, and the Open button is disabled.

To configure a message so that it expires 24 hours after you send it, insert the 
following header into the message:

X-PostX-ExpirationDate: +24:00:00

The recipient can open and view the content of the encrypted message during the 
24-hour period after you send it. After that, the Registered Envelope displays a 
message indicating that the envelope has expired.

To disable the decryption applet and have the message attachment decrypted at the 
key server, insert the following header into the message:

X-PostX-Suppress-Applet-For-Open: true

The message may take longer to open when you disable the decryption applet, but 
it is not dependent on the browser environment.
