How to stack signatures to apply a disclaimer to external messages

Scenario

You wish to apply a 'contact details' type signature to all emails sent from your organization, but you only want to add a disclaimer for external emails.

Resolution

Follow these steps to resolve the issue similar to the above scenario:

1. Create one generic template with the 'contact details' signature (this will be applied to every email).
   
   
2. Create another template with the disclaimer (this will only be applied to emails sent to external recipients).
   
   
3. Set signature rules for the generic template.
   
   - Click MANAGE against the required signature template.
   
   - Select the Advanced Rules tab.
   
   - In If this signature is applied section, select the Process the next signature option.
   
   Process the next signature means you can apply multiple signatures to a single email message (using the server-side feature).
   
   NOTE: Signatures are processed from top to bottom, as displayed in the All Signatures tab. 
   
   
   
   
4. Now, set signature rules for the disclaimer template.
   
   - Click MANAGE against the required signature template.
   
   - Select the Advanced Rules tab.
   
   - In If this signature is applied section, select the Do not process the next signature option.
   NOTE: Signatures are processed from top to bottom, as displayed in the All Signatures tab. 
   
   
5. Click SAVE CHANGES to save the changes made.

Once the two signature templates have been updated, you can verify the rules attached to them on the signature card.
