I still think you'll change your mind the day your address is the
one being forged and the target of a million bounces.

You didn't answer when I asked this before so I'll try again. Viruses
virtually always use legitimate addresses found in the local contact
list or headers of received email - just not the real sender. How
does your system ensure that rejections by the next hop can only
be returned to the real sender, not a forged address? If you can't
do this yourself, how can you expect the rest of the world to do it?
If you can, I'd like to know how.
