	No, that's clearly one of the things they do try, but I believe 
that they use an envelope sender address something like 
"orbs-tester@mail.foo.com", so as to give you an indication that this 
is a test.

	They aren't trying to hide their identity, and they aren't 
forging the headers, because headers != envelope address.
