This kind of thing won't really work unless everyone with an E-mail address does it and I just don't see it. It'll get through, just like regular junk mail. And we'll just learn to throw it away when it gets here rather than call 15 advertisers every month to ask them to stop.


There's the problem. It won't work unless everyone does it, so I won't do it. Everyone thinks that, no one does it, so nothing ever gets done (or fixed, or whatever). Same with voting, fighting Big Brother, not releasing buggy software, dealing with spam, etc., etc.

To me the excuse of "I can't make a difference doing it when so many other people are not doing the same." is somewhat less than a bad excuse.

How about "Doesn't work and makes the problem worse"? Is that a good enough reason?

This kind of solution falls under the rubric of "backscatter". Backscatter doesn't work *and* has the amazing property that you can utilize it to initiate DDoS and phishing attacks. Pass, thanks.

The primary issue is that there is no such thing as positive sender identification with respect to email. I can't verify that a stranger is who he says he is. I can't even verify that my whitelist is who they say they are as they can be compromised fairly readily and then their machines start spewing spam.

The only thing that differentiates spam from non-spam is *content*. Any method which uses something other than content is doomed to failure.
