"nicer" paths to xenitec have been suggested, possibly because of a
misunderstanding of what Greg and I were discussing by email.  (part of
which was quoted in <1991Jan14.234354.8055 at eci386.uucp>).

We weren't discussing the path to xenitec -- we were discussing the way
smail-2.5 interprets (or misinterprets!) what it finds in pathalias
output for domain gateways.  xenitec was merely an example -- all data
was being quoted from Greg's pathalias output.  To restate my email to
Greg with a little more context:

If the pathalias output contains a line of the form

.xenitec.on.ca	lsuc!utai!watmath!%s

then smail-2.5 seems to route the address user at foo.xenitec.on.ca as
lsuc!utai!watmath!user, which is wrong.

For the pathalias output above, smail-2.5 should route
user at foo.xenitec.on.ca as lsuc!utai!watmath!foo.xenitec.on.ca!user.
Whether this is optimal or convenient is beside the point! :-)

Greg's fix was intended to correct the bug in smail2.5.
