Er, no.  It is never wise to assume that a mail path works both ways.
An example I saw recently: someone was sending mail from Tektronix to
MIT using the path fragment ..!allegra!eddie!athena!user.  It was their
dumb luck that allegra realized that "eddie" was the same machine as
mit-eddie (aka eddie.mit.edu), AND that eddie  would resolve "athena" as
athena.mit.edu (which is mit-athena in the uucp world).

How did I trip over this one?  The recipient was trying to reverse that
path and send along it.  Oops.   Didn't work.  (mit-athena was looking
for the uucp machine eddie, and losing.)

Don't try this one at home...
