How do I stop duplicate disclaimer stamping?

Introduction

This document describes how to disable disclaimers when an Email Security Appliance (ESA) stamps outbound email with a disclaimer, even if the email already has one.

How do I stop duplicate disclaimer stamping?

Create a text resource via the Web GUI:

1. Log into the Web GUI.
2. Mail Policies > Text Resources > Add Text Resource, name the resource: disclaimer_1.
3. Select Type: Disclaimer.
4. Paste your Disclaimer in the text box.
5. Submit and Commit.

Create a message filter to stamp outbound mail and ignored previously stamped mail:

1. Log into the CLI of your appliance.
2. Issue the filters command.
3. Select New from the menu.
4. Paste the filter below (please ensure you replace the SNIPPET portion with a short sentence from your disclaimer).

   no_duplicate_disclaimer:
   if (sendergroup == "RELAYLIST")
   {
   if not (body-contains("SNIPPET FROM DISCLAIMER", 1))
   {
   add-footer("disclaimer_1"); 
   }
   }

5. Press the enter key and return to the main CLI prompt.
6. Issue the commit command.

{
add-footer("disclaimer_1");
}
}
