I agree.  The assumption is everything, right?		:-)

When it leaves a site with a From: line of user, or host!user, are
either of those an address or a path?  I say an address.  So host1
gets it and makes it host1!host!user.  Is that an address or a path?
I say it's a path.  I also say it was wrong for host1 to assume
it was a path when it got it.

I still say leave it alone under all circumstances.  There's no reason
you should propagate someone else's error.  Keep the path info in From_.
