message forwarding and displays the 
Forward button in the message bar. This 
header overrides the default profile 
setting.

X-PostX-ExpirationDate

Defines a Registered Envelope’s 
expiration date before sending it. The key 
server restricts access to the Registered 
Envelope after the expiration date. The 
Registered Envelope displays a message 
indicating that the message has expired. 
This header adds an encryption setting to 
the message.

If you use Cisco Registered Envelope 
Service, you can log in to the website at 

http://res.cisco.com 

and use the 

message management features to set, 
adjust, or eliminate the expiration dates 
of messages after you send them.

A string value containing 
relative date or time. Use the 

+HH:MM:SS

 format for 

relative hours, minutes, and 
seconds, and the 

+D

 format 

for relative days. By default, 
there is no expiration date.

X-PostX-ReadNotificationD

ate

Defines the Registered Envelope’s “read 
by” date before sending it. The local key 
server generates a notification if the 
Registered Envelope has not been read by 
this date. Registered Envelopes with this 
header do not work with Cisco 
Registered Envelope Service, only a local 
key server. This header adds an 
encryption setting to the message.

A string value containing 
relative date or time. Use the 

+HH:MM:SS

 format for 

relative hours, minutes, and 
seconds, and the

there is no expiration date.

X-PostX-Suppress-Applet-F

or-Open

Indicates whether to disable the 
decryption applet. The decryption applet 
causes message attachments to be opened 
in the browser environment. Disabling 
the applet causes the message attachment 
to be decrypted at the key server. If you 
disable this option, messages may take 
longer to open, but they are not 
dependent on the browser environment. 
This header overrides the default profile 
setting.

A Boolean for whether to 
disable the decryption 
applet. Set to 

true

 to disable 

the applet. The default value 
is 

false
