Oh, $DEITY, another hackor who used to do "things" - I can hear it now:

   "Our computers were so old, we had to bang two rocks together to get
   ones and zeros."

   "Rocks??? You had rocks??? We had to take mud and mold it into balls
   and bake them in the sun to get something to bang together, except
   that the baked mud would crumble into dust after about 80 to 100
   characters..."

   "Mud??? You had mud???  We had to use dinosaur poop and...""

It's really not that hard, as long as you have a clue about what you are
doing. You gain those clues by reading, or having a buddy show you.

In my posting, I wrote:

but this one is easy. Look at your mail, and you'll soon see a header
that is found ONLY in mail that actually came from you. Fake bounces
won't have it, and therefore, out she goes.  Another clue is that I
only send messages in ASCII text, and NEVER as windoze binaries. A
real mail from me that is over 6,000 bytes is unusual to say the least.
