Eric,

I _was_ feeling a bit elitist when I posted that note, and on reflection I
think I should have put a "half :-)" on my proposal to make Path: lines
look less like mail paths.

There is no disk space requirement for smail, other than for the sources
and the binary.  (And if you have room for the netnews software, smail is
peanuts in comparison -- which is why you are able to consider bundling it
with TMN.)

Smail is able to run without a database.  Or, rather, with a truncated
database:

	smart-host	uunet!%s

This assumes that you are one hop from uunet and want to use it to route
your outgoing UUCP mail.  You could, in your case, say:

	smart-host	vu-vlsi!rutgers!%s

Note that the "-" in smart-host may or may not be correct, I don't use it
here since I have a full database.  Check the smail docs.

Registering in the u.* files costs nothing; smail is available for free;
you don't need a full database, or a 32-bit machine to run pathalias since
you don't need to run pathalias; smail will run on SysV or SysIII or BSD,
and probably V7 and Xenix.

I don't see that I'm asking anything unreasonable.  I hope that you do
bundle smail with TMN; it's small, and TMN can then assume its existence.
Make sure that smail is only optionally installed, since many sites will
already have smail or something equivilent and won't want to have to edit
the TMN Makefile to keep their MTAs from being overwritten.
