Keep in mind that spammers don't check bounces (and neither do a lot 
of "legitimate" bulk mailers).  Add in subscriber churn.  I seriously 
doubt you could subscribe at any ISP with the name "john" and not 
immediately start receiving spam.

So you need to measure two things.  Percentage of traffic to valid 
email addresses, and overall mail to invalid addresses. The latter is 
poisoning the email address space.  My domain currently has about a 
dozen valid accounts, and bounces 10,000,000 messages a year 
(doubling every year).  That's an extreme example.  But last summer I 
turned on a domain that had been offline for two years and got 400 
messages in 4 hours.  20% from legitimate companies who had 
apparently been ignoring bounces for two years.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
