So you see, the reputation has nothing to do with your mom, and everything to do with the controlling entity, her ISP. Which makes the whole address-based sender reputation scheme almost workable, if you ignore the scaling issues.
That's suspiciously close to "Ralph Nader or Ross Perot could have been elected President, if you ignore the scaling issues". :) Other than that, what Matt said is correct - the problem is that legitimate mail can come from literally millions of places whose reputation we have no clue on....
