Cisco Cisco Email Security Appliance C160 Mode D'Emploi

The Cisco IronPort appliance can add a default disclaimer above or below the text 
(heading or footer) for some or all messages received by a listener. You can add 
disclaimers to messages on the Cisco IronPort appliance using the following 
methods:

Via a listener, using the GUI or the 

listenerconfig

 command (see 

).

Using the content filter action, 

Add Disclaimer Text 

(see 

Using the message filter action, 

add-footer()

 (see the “Using Message 

Filters to Enforce Email Policies” chapter in the Cisco IronPort AsyncOS for 
Email Advanced Configuration Guide). 

Using a data loss prevention profile (see 

).

Using message modification for Outbreak Filters to alert the user that the 
message may be an attempt at phishing or malware distribution (see 

). Disclaimers added for this type of 

notification are added above the text.

For example, you can append a copyright statement, promotional message, or 
disclaimer to every message sent from within your enterprise. 

Prior to using disclaimer text you have to create the disclaimer template. Use the 
Text Resources page in the GUI (see 

) or the 

textconfig

 command (see the Cisco IronPort AsyncOS CLI Reference Guide) to 

create and manage a set of text strings to be used.

Once you have disclaimer text resources created, select which text strings will be 
appended to messages received by the listener. You can add disclaimer text above 
or below a message. This feature is available on both public (inbound) and private 
(outbound) listeners.

If you send a message that consists of text and HTML (Microsoft Outlook calls 
this type of message a “multipart alternative”), the Cisco IronPort appliance will 
stamp the disclaimer on both parts of the message. However, if your message has 
signed content, the content will not be modified because the modification will 
invalidate the signature. Instead, a new part is created with a disclaimer stamp that
