That's a very dumb thing to do since spammers seldom use
their correct 'From' address, and they often use the 'From'
address belonging to an innocent third party.
Anyone who bounces misdirected spam back to me gets
reported to SpamCop, which can result in your mail server being
blacklisted.

In Windows Live Hotmail you have the option of bouncing junk mail back to the sender. Is there any way you can get that in Windows
Mail?
