Help needed with uux and uucp through two machines

[Bob Hoffman]

The reason you can send mail to a site by specifying a path with
more than one machine in it is because the mail program itself takes
care of parsing the multi-machine address.  For instance, the command
used on your machine to send mail to "macha!machb!foo" would be

	uux - macha!rmail machb!foo

In a more general example, only the first machine name is split off
by each machine's mail program in succession and the resultant command
is queued up for uux, e.g.

your machine:   uux - macha!rmail machb!machc!machd!mache!foo
on macha:       uux - machb!rmail machc!machd!mache!foo
on machb:       uux - machc!rmail machd!mache!foo

...etc, where the same thing happens on every machine in the path, until
you finally get to the destination machine where uuxqt is given the
command:

on mache:	rmail foo

In summary, the uucp and uux programs will only accept a single hop
per command.  Maybe a front end (ruux?) could be built to do roughly
the same thing as rmail, only in a more general sense.
