Yup, it's not a bad idea and has been tried before elsewhere- "point of injection" seems to give good hits discussing this idea. It is past it's time though now, most spammers are now using bots or zombies to send spam- as the spam originates there (in the SMTP sense) and passes through legitimate servers it doesn't work that well anymore. I've been thinking about how to combat spam bot networks, I even spent an hour or so writing something up but the computer I read my mail on is still NT4, and in the excitement I had too many IE windows open and it crashed loosing the draft.
