	Okay, so far as that goes, that's fine.

	Uh, oh.  That's bad news.  If you're going to have a mail 
exchanger for a domain, it should be able to either directly deliver 
mail for *ALL* users, or it should be able to forward mail for 
specific users to a more appropriate machine (using mechanisms 
outside the DNS).

	What you've got is a recipe for continually bouncing mail, and 
under apparently random circumstances certain users will or will not 
receive anything.
