In general, the Path line is to keep track of where an article has
already been, not to provide a working mail reply path.  Part of
the reason is that the Path mechanism just can't deal with the various
syntaxes of various nets.  That's what From is for.  I recognize that
many machines still use the Path for replies, but that's only because
their mailer doesn't understand internet domain addresses, that problem
should go away within a year.

Jack Jansen makes a good suggestion for a specific improvement, however,
and once we have a significant number of sites that understand host.arpa!user
that seems like a good change to make.
