Does your machine receive mail directly from the Internet, or does
mail from the Internet go through Google first? Your text below
suggests that it is the latter.
Whatever the solution, there will at the very least need to be a
table that says what users are delivered locally, and probably a
table that says what users are hosted elsewhere.
