Alf,

Similarly to the "X.400 to Internet" problem, we may have to face a "Internet
to X.400" problem someday. If you make the assumption that users dont have
access to mapping table, then the Internet equivalent of:

   /c=us/admd= /prmd=Internet/dd.RFC-822=user(a)some.place.edu/

Is a gatewayed X.400 address, e.g. something as:

   /C=us/ADMD= /PRMD=xnren/O=UW-Madison/OU=CS/S=Hansen/G=Alf/@x400.net

Were the domain <x400.net> designates the x400 world for Internet users, on
the same way that "/c=us/admd= /prmd=Internet/" designates the Internet world
for X.400 users.

CAVEAT: there is no such thing as an <x400.net> know. This address is invalid.
It is only an example. Dont use it. In fact, there no such thing as a fully
connex X.400 net know, and one as to pick up "the right gateway".
