In theroy that idea isnt even that great, and in practice a hygene server is a better place to do the most course obvious spam. There is stuff that is very obviously not wanted such as items coming from rouge servers that we can prove thanks to SPF or Sender-ID being setup correctly. There is no reason that a server that can verify that another server has no right to send should pass on a potentially risky email to the user, it is actually very irresponsible to do so especially since you are going to treat a user that may have no clue about email headers as an idiot because they clicked on a message that if you had a script take two milliseconds to look at could have told you it was spam. Not everyone is a computer scientist, and stuff that is obvious should be dealt with long before your users have to deal with it manually.
