While that sounds like a good idea, it generally is not, for the following reasons:
1. Many spammers send out millions of messages each day, often with randomly generated recipient email addresses, and with no regard for whether or not each email address is valid.
2. Many spammers use innocent people's email addresses as their FROM address. If you were one of those innocent people, you could receive hundreds or even thousands of bounced spam messages each day.
3. Spam messages already cause lots of Internet traffic. Adding bounced spam messages to the scenario would make things even worse.
