I think spam already tells you where it came from, via received: headers and IP packet source addresses. I don't see that spammers are managing to spoof IP addresses, and when a received: header is forged, I think it's pretty easy to find out, if you're at the police investigation stage.
So what does DKIM add for spam prevention?
