And all dialup networks.  Which can lead to the bizarre situation that 
if you're relaying through your mail server from a dialup IP, and mail 
goes thru SA, you'll get a high score.  There're several ways to prevent 
this from happening, of course, for example, to run an extra smtpd on a 
nonstandard port that doesn't push mails through SpamAssassin, or just 
to disable the damn RBL stuff in the SA config (I did both, greylisting 
is more effective than the suspicious RBL stuff anyways).
