I wouldn't think of doing that....

First, what makes you think sending "delivery failed" messages will change 
anything?  Spammers don't check those things.  It would take time and 
effort...something no spammer wants to do.

Second, there is very little chance your messages would make it back to the 
spammer.  They generally don't supply correct return address information. 
You'll just end up sending those messages to innocent by-standers.

So, don't waste your time.
