Help needed with uux and uucp through two machines

[sherm at pegasus.UUCP]

The capability of uucp'ing through multiple machines is in
System V.  The syntax is exactly as the author of the original
question suggested, (uucp macha!machb!machc!~/user will put a
file in the user's subdirectory of the public directory).  Only
forwarding to the public directory is permitted.  Uucp spools a
temporary file on the intermediate machine, then sends it to the
next with (possibly) another forwarding path.

In order for this to work, the uucp on all intermediate machines
must understand the forwarding syntax.  Therefore, you can only
forward (now) through other machines also running System V.

As the manual page says, you must be sure that all intermediate
machines are willing to forward uucp traffic.  According to
some documentation (not the man page), forwarding is on by
default to everywhere.  However, on my system, a recent release
of the uucp code implements it such that forwarding is denied
by default unless a machine is specifically listed in a forwarding
file.  This isn't documented as a security feature, so it might
just be a mistake.  However it does allow forwarding to any
machines listed in the forwarding file.
