This looks to me like someone is spoofing your address to make the From 
line look legitimate.  Your internet provider does not know the 
difference, so it sends the reject messages to you instead of to the 
real sender.  There was a lot of this about a year or two ago.  I do 
not recall the names of the big ones.  Remember the news about 
computers around the world being messed up with traffic overload?  Does 
not affect your Mac.
