There already is such a thing, though it doesn't work quite the way you describe. Check out RFC 976, "UUCP Mail Interchange Format Standard". According to that, your first example would become: mail mtune!UNIV.EDU!theirneighbor!theirbox!friend Since mtune understands domains, it should be able to deal with the UNIV.EDU part, and your mail gets sent happily along its way. It's almost, but not quite, what your idea says. The big problem with your system is: what if EDU or UNIV, or whatever other meta-machines you might recognize, are coincidentally the *real* names of *real* machines? -> I thinks this also eliminates precedence problems (of the NO -> NO NO NO NO variety.

From a domain-based machine, it would more likely be "mtune!p.g.fox@ATT.COM". ->-- -> Paul Fox, AT&T Information Systems, Middletown NJ. -> [ihnp4|vax135]!mtung!pgf (201)957-2698 --Pat.
