  Using Text Resources
Adding Disclaimer Text via a Listener
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 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 says 
Content-Disposition inline attachment
.” For more information on multipart messages, see 
“Message Bodies vs. Message Attachments” in the “Using Message Filters to Enforce Email Policies” 
chapter.
The following example shows how to select a disclaimer to apply to messages on a listener via the GUI:

Editing a Listener to Include a Disclaimer
Adding Disclaimers via Filters
You can also append specific, predefined text strings to the disclaimers of messages using the filter 
action 
add-footer()
 or the content filter action “Add Disclaimer Text.” For example, the following 
message filter rule appends the text string named 
legal.disclaimer
 to all messages sent from users in 
the LDAP group “Legal:”
Disclaimers and Filter Action Variables
You can also use message filter action variables (see “Action Variables” in the “Using Message Filters 
to Enforce Email Policies” chapter for more information). 
Add-Disclaimer-For-Legal-Team:
if (mail-from-group == 'Legal')
{
  add-footer('legal.disclaimer');
}
