My ISP (Qwest) uses the commercial version of hotmail as their mail
service for subscribers. In over a year, I don't remember seeing a
single spam email.  I suspect Tim's argument is the reason. Hotmail is
*known* for spam, so they would get lots of practice at recognizing it
and removing it, and thus become very skilled at it.
