The enclosed file is a short script to edit the output
of pathalias.  The idea is it removes all paths that
pass through `smart-host'.

This is done to take advantage of MX mailers on `smart-host'.
It happens like this.  In my case `smart-host' is uunet.uu.net
if I build my paths using the world maps then from here to
say agate.berkeley.edu is uunet!mtxinu!ucbvax!agate.berkeley.edu.

As uunet is `smart-host' this path would be eliminated.  The result
of this is that uunet will do an MX lookup on agate.berkeley.edu
and deliver the mail via the internet saving time and money for
mtxinu and getting my mail accross faster.

It also takes my paths file from 800k to 200.

shar and enjoy.
