[rt-users] No permission notify

Yeah I'm talking about backscatter, when someone sends spam as a spoofed 
user and the smtp server bounces that spam back to the spoofed address, 
effectively relaying spam for them. Postfix does recipient lists so the 
majority won't bounce for email addresses not in my /etc/aliases, I have 
procmail and spamassassin on the entry of my public queue/emails so spam 
is not getting in, but it will bounce back (the RT response) when 
there's no permission on a private queue. It's not a major problem I was 
just curious if those no permission replies can be disabled. Or at least 
don't attach the original message to the response.
