Fifteen years ago, this was a good idea. Today, it isn't. If you've ever been Joe-jobbed, you'll know why. If not, welcome to the Internet, I hope you'll like it. If the recipient doesn't exist, it's an almost certainty that the sender of the email is *not* the real sender. Spammers take a /legitimate/ email address belonging to someone else and put it in the envelope sender field, and fire off the spam to hundreds of thousands recipients who may or may not exist. Those who bounce the mail they way you want to will then send an email to the innocent who happens to have the sender e-mail address the spammer forged. He then gets thousands of bounces within a short period of time, and the bounces will continue to trickle in for weeks. By implementing what you describe, you're only helping to hammer innocent people's mailboxes. Please don't.
