It depends on the level of expertise of the forger and the general answer
is NOT A CHANCE, not one in  a million, zilch, end of discussion. I don't
know the details  how to do it but  I have seen it done  and I understand
the  principles well  enough  to  be totally  convinced.  With the  right
equipment  and knowledge,  there  won't be  one disk  unit  in the  whole
network with the real origin logged. The only boxes which will have had a
way to give  a clue to the real  origin of the message will  have been IP
routers, and  these things  process thousands of  packets per  second and
certainly don't log their origin,  destination, contents and the physical
line  from which  they came  as a  matter of  routine. If  LISTSERV could
easily detect forgeries it would do so.
