I have a friend who's email service sporadically bounces my email.  Why? 
  Because I own my own domain, I use my hosting company's email servers 
instead of my ISP's and a small number of their customers are spammers. 
  Whenever their spam gets above a certain threshold, her ISP blocks any 
email access from those servers, and cuts us off.  This is why I dislike 
blacklists: they're just about guaranteed to produce at least 99% false 
positives because they're just an exercise in throwing the baby out with 
the bath water.
