I guess in some ways this is similar to habeas (though habeas isn't cryptographically secure). I guess though crypto signing an email is probably beyond the technical competence of these mass mailers. They tend to just buy a big box like an ironport (anyone got any experience with these - contact me off list), and use some tool to send their mailings out. Though perhaps some of us spam assassinators should join their forums to point out some good solutions like this.Couldn't they use an encryption scheme? That is, they sign their email with a string that has to (crypto-) match the IP of the system that the email originates from? SpamAssassin (and others) could check this as a means of allowing the SPAM through. The obvious advantage is that this SPAM can now be traced if it is sent to the wrong person.
Matt.
