Relevant Products: Signature Manager Exchange Edition
You would like to apply a specific signature for replies or forwarded email messages using Signature Manager Exchange Edition or Mail Disclaimers.
Within these products, you create signature policies to control which signature template should be used when a defined set of circumstances is met. In short, a policy can be thought of as a set of rules that must be met for a template to be applied to email messages.

8. Click OK to exit back to the condition.
9. Update any other elements of the policy as required.
In this scenario, it is likely that you will have one signature policy that is applied for any new messages that you send, and another policy for replies and forwards. Both policies would usually need the same conditions (so they are applied under the same circumstances) BUT the reply policy will have the additional message headers condition.
It is also advisable to add an exception to the policy applied for new messages. By adding a One or more message headers contain specific words or character sequences exception with the same In-Reply-To settings detailed above, you will ensure that your ‘new messages’ policy is NOT applied to reply/forwarded messages.
