You can't really stop forging the From: that way. Neither will SPF stop forging email headers. Nothing really will, except a total redesign of the smtp protocol or a totally new protocol. Grey listing and other spam filtering techniques will help a lot. Since emails with forged headers almost solely are from spammers you will block many forged emails that way.
