I personally have a dot-email address. And you left out dot-edu. And I get a fair bit of ham from other weird TLDs. So I think a whitelist is a bad idea. But that's because I prefer to have some spam get through than have ham get blocked by mistake. Even with my very sloppy algorithm, the only time spam ends up in my inbox is if a spammer spoofs one of my contacts, and that is extremely rare.
