In news.admin (<579@nusdhub.UUCP>), rob@nusdhub.UUCP gives an interesting
and deatiled method for sites to maintain dynamic mapping information.

In his words,
>Here is the mold for a news-based self-mapping scheme.:

It's a cute idea, except that it has one fatal flaw.
	A news link does not imply a mail link.
I won't name specifics, but here's an example.  Our gateway machine bbn.com
exchanges articles with host.do.main, yet if you send mail to us with
the "path" ...!host.do.main!a!b!user, that mail stands a good chance
of getting rejected because...
	we don't send mail UUCP-like mail to host.do.main!
