This type of rerouting is reasonable because you are talking about a fully
qualified domain.  There can only be one host.foo.edu, so sending mail there
directly is OK.

There has been discussion that if, say, "even" lists "smore" in its map entry,
then you can assume that their "smore" is the same as the "smore" you list
in yours.  Of course smail doesn't do this kind of routing, but this, too,
would seem reasonable.
