I believe that would be very bad news.

The risk is that you will have set up a potentially serious loop,
for which there is only one way to detect and stop it before there is
a melt down. All it would take is a misconfigured client or MTA to
remove certain headers before sending the message on, and you and
everyone else would be toast.
Before you take a shotgun with a hair trigger and load it with
thermonuclear shells, you might want to give some consideration to
what it might do when you go away and leave it pointed in your
direction -- especially when there are children and pets around, any
one of which might accidentally set it off.
