Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

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.
