Hiding the true sender 

I just got a spam where the fictional 'from' field was actually MY e-mail address, which had the added effect of making it impossible to block. Does anyone know how you find out the true sender address, and/or shouldn't something about this fraud be in the article?
Also, isn't there someplace you can forward spam e-mails to and the organization will track down the sender and prosecute them? I know 419 scams have that.
