I think I have responded. I apologize for my brittle attitude but I have been through this process once already. Every idea has problems but many ideas are accepted and implemented with far less information supplied than what I give. Please see the reply I just posted - I go over it again.

If I give implementation details then people probably can find quibbles. I've done this for three years - the quibbles don't impress me in face of my success. Others have done it for a year, still others for a shorter time. Michael Tokarev in Moscow knocked hell out of Alan Ralsky for a while. That didn't get much publicity at the time: why risk tipping off Ralsky by bragging about trapping Ralsky's spam while it was still happening? Only some of his spam was trapped, of course - Ralsky has 190 servers, the one honeypot in Moscow wasn't collecting it all. But it may be that that one honeypot did bring all of Ralsky's Dallas servers to a halt because the one honeypot got all the throwaway dialup accounts Ralsky had terminated. I can't call Ralsky and ask - I have to guess. People did say in NANAE that they weren't getting Ralsky spam at the same time.

The quibble I can remember right now is that if you do this and it works (note WORKS) then the spammers will move to a different form of abuse. In other words, it's hopeless. How am I supposed to handle that? In fact I can*, but when do people start looking at the idea and thinking about what it means and how they'd use it instead of submitting me to a 3rd degree interrogation? It's simple: set up a system with no email function that accepts relay email. That's the entire basis of the idea. You don't want to be an open relay, so don't be - don't relay anything, just capture what comes. You can act against spammers just on the basis of their relay tests - you should capture relay tests because almost certainly spammers are attempting them for that IP.

If you go one step further and deliver a relay test, in a timely fashion, I hope keeping a copy, then you should receive spam as a result. That is spam that otherwise would have gone to a real open relay and would have been delivered. Don't deliver it.

If a spammer figures out it's a honeypot then wait for the next spammer to find you. If he doesn't continue to deliver relay tests for him (at least) and continue to not deliver spam. Send appropriate complaints based on the spam you receive. If you want and can, change the IP of the honeypot if it is discovered - that forces the spammer to do it all over again, if he continues to test in your range. You coast, he works. That's a small win but it is a win.

Better yet, create and run an open proxy honeypot. There's a much greater chance (these days) that the spammer will connect to the honeypot directly from his own IP, which you will learn. Then you have evidence of abuse to show his ISP.

In the other posted reply I have a link for GypsyProxy. I've only run it once, I can't vouch for it. It seems to be a good idea. I don't doubt a better idea is possible - I thought that was the focus of ASRG - better ideas.

When spammers develop countermeasures the challenge will be to defeat them. Why is it required to anticipate everything they might do (and haven't yet done, based on successful evidence) in order to get the ideas considered?

Thanks again for your reply -  I continue to appreciate your interest.

*If honeypots work so well that spammers must move to a different form of abuse the entire picture will be different. For honeypots to do that there have to be a lot of them. If there's a lot of them then many people will be working to defeat relay spam. If they defeat relay spam they'll know it, and thereby know they can, working together, end a form of abuse. The expectation should be that, if there's a new form of abuse, a large number of people, working together, can make that end as well. (This discussion is probably 95% accurate. someone surely can find a quibble. It is not productive to devote all energy to finding quibbles, is it?)
