*PROPER* domainizing helps totally here.  If tut.edu is a machine in
the fu.edu domain, then it should be named tut.fu.edu.

You cannot guarantee that it is always safe to put a "believed-unique"
name after a fully-qualified domain name.  *BUT*, if all the names the
outside worlds sees are ALWAYS fully-qualified names inside registered
domains, everything works fine.  Note that ALWAYS includes things
like the Usenet Path: line and the UUCP-mail From_ line.
