That's true, but if a forwarded message bothers you, just blame the 
forwarder (who substituted their own domain for the original one).

...even if the forwarder rewrites the sender address to their own domain?  
Are you kidding?  This is simply not possible.  Information can always be 
copied and "forwarded".  You'll never be able to prevent that!

That would be pointless, just like the various "no-copy" bits in the TV 
broadcasting or storage medium industry.  Such a thing can only work if 
ALL devices honor it, i.e. non-compliant devices are outlawed.
