We (the UUCP Project smail support organization) STRONGLY DISCOURAGE
use of ROUTING == ALWAYS.  Please don't do it without due consideration.
People get frustrated when their mail get rerouted for no good reason.

Now, to answer Brian's queston

>> How do I force costs to be used on bang paths?

This is was done intentionally in smail2.3 to minimize overhead on
mail that's just passing through.  I had several requests for the
feature, so I added a #define GETCOST to cause the paths file
to be searched for the cost of the first hop in the route.

This feature will be in the next release of smail.

The next release is due to go into beta test before the June
USENIX conference with general availability "real soon now."
