    Wrong.  The Moral:  don't put full domain names into email paths if
    they're going through the Internet and you don't want them short-circuited.
    Hack the path to be something like
    	noe!packet_radio!kg6kf_ampr_org!callsign!callsign

Ugh! Ugh! Pain... Fro two reasons: this is a horrible hack, and, and, let me
repeat my NHO, this is Internet parochialism. There is nobody that has ever
said that domain names are restricted to the Internet. As one regrettable
example, the UK NRS uses things that looks suspiciously like Internet domain
names, with a reverse order, administered by central authority. The rest of
EUnet, a (mostly) UUCP network, also uses domain names (internet style, btw),
with aanother central authority (well, almost).

    If you shoot mail into the Internet with a fully-qualified domain name
    in the address -- yes, Paul, even if it's in the Path line -- than you
    should expect people to follow it.

But damnable Internet sites should NOT expect domain-style names to be
Internet names at all, as anybody can write a.b.c! And unfortunately...
    
    UUCP host names don't come with an enforceable central naming authority,
    but domain names do.  If you don't want to use them, CHANGE YOUR GATEWAY
    CODE!

...no gateway code can cope with this, because there is NO way an Internet
gateway can transform a non internet name (domainized or not) into an
Internet one all of the time, simply because it does not have MX records or
maps for all the funny domains out there.
