The idea of rating a site by it "smartness" is a great idea.  I
have had problems sending mail because I didn't realize there
was a site in the path that was going to mangle addresses in the
header.  I always figured that a new field should be added to
the uucp map wherein a site could specify its "smartness": "I only
do bang addresses" or "I know about .ARPA addresses", or "I map
bang addresses into Internet addresses and then reroute them".
Sites could even say "I know about the .XYZ domain" so, as long
as "domains" made sure they had enough links (all non-centralized,
of course) you could do domain like addressing.
With information like this, one could figure out (or at least
make a better guess) at the address to ship mail too.
