Adding Signature based on header?

I have MailScanner on a Postfix box.

I run one instance on Postfix and 2 Postfix listeners, normal SMTP, and
a separate Authenticated SMTP listener.

I have a Signature rule to only sign email from my internal mail servers
IP address.  

How would I apply this signature to email sent via the Authenticated
SMTP listener?

AIUI Postfix adds some sort of "Authenticated User" header, can I have a
From: rule based on that?

As an aside, thanks to anyone and everyone who has answered the numerous
questions I've posted over the last week or so, it's much appreciated
and the end result is fantastic assuming it's not about to implode on me
