How would this work.  The ISP is enforcing these rules?  But the email
is not anonymous to the ISP.  Or is the email going through a 
remailer.

Why not just have an ISP say you can't send more than 1000 emails a
day.  But then what stops other ISPs from using different rules to
get the business of spammers.
