It's unlikely that _any_ X.400 gateway would accept mail from you which
was to be sent back to Internet.  With both sender and receiver on
Internet, they'd have no one to bill for services rendered.

Not sure what you mean by well-defined, but sprint.com, attmail.com,
mcimail.com, and cgnet.com are all working fairly well.  In Europe 
there are several gateways providing mail exchanger service to 
domain-style addresses which are designated for various X.400 systems.

Most often they will gateway only to addresses in their own administrative
domains (ADMDs), such as ATTMail, SprintMail, etc., which are not 
necessarily worldwide, but certainly can't be called local.  These
companies (AT&T, Sprint, MCI) often have agreements with others over
the exchange of mail, but such arrangements don't cover mail originating
on (or reaching them via) Internet, because of the payment problem, as
I mentioned above.  They are in business to make money; they don't 
provide service unless someone (sender, receiver, or other carrier) 
pays for it.
