Presume an adversary with computing resources that routinely range in the area of "tens of millions of systems", with all the processing, memory, disk, and bandwidth resources that implies. Presume that those systems are capable of coordinated or independent tasks as designated by the adversary. Show how this approach will have a meaningful effect on the adversary's ability to generate/transmit [SMTP] spam. Simultaneously, presume the existence of hundreds of thousands of highly useful mailing lists (e.g., "ietf", "nanog") with varying numbers of members and show how this approach will not adversely affect their ability to function in the way they've been functioning for decades. I don't think you can do this. I think you're trying to drown someone who owns the ocean, and that the attempt is futile. But perhaps you have an approach that's eluded others, that overcomes the obvious problems, and I just don't see it yet due to insufficient caffeine intake. ---rsk
