As I understand it, it is proper for transfer agents
to rewrite from: fields so that they point back to 
the sender.  Is it "proper" to do the same with to:
and cc: fields?  

For example:  tom at host1 sends a message to host2!dick,
and cc's harry (who is also at host1).  How should that
cc: line look when host2!dick receives it?  If that line
is not rewritten, then it must be the responsility of
dick's UA to determine that harry's host must be the same
as tom's, which seems pretty messy (what if there's also
a user named harry at host2, for example?).
