Would you Warranty Your Email?
Kurt writes "A team from the University of Michigan is proposing an economic solution to spam. Instead of relying on technical solutions or government regulations, they use a sender warranty system. In some cases, they argue, it can even be superior to a perfect filter with zero cost, and no errors. Their working paper is available at SSRN. With the caveat that some infrastructure is necessary (isn't it always?), they also claim their approach restores control to the recipient, halts spam, and creates a marketplace for valuable information exchange."
The idea is basically this: You (the recipient) put a value (say $10) on incoming mail from strangers. If someone wants to send you mail, they have to put that in an escrow account. Then if they meet your requirements, you can recieve the mail. -- If you don't like the mail from any reason, you can take the money from escrow. If you don't do anything, escrow will be released after some time. Oh, they mention that this might not be neccessary for people you already know (whitelists).
This is just lame. The amount of "infrastructure" required is totally ridiculous.
They ignore the fact that email is a general communications media / People who do not like eachother do email because it's practical / but under this nutty system, people would only email people they trust not to "steal" their money in escrow. Mailing lists, anyone?
Once again, someone thinks that you can "solve" spam for the recipient at a huge penalty to a legitimate sender.
Arrg! I hope they didn't get paid to write this tripe.
I send you email. I have to put money in an account.
You receive my email, but you've set a monetary level to be checked before it is delivered to you. If I didn't put enough money in my account to meet your level, it doesn't get delivered.
Now, you read my email and don't like it. You get to collect the money I have in my account at the level you set.
If you do like my email, I go on a whitelist.
Example #1: I put $1 in my account, you set your level at $5. None of my email will ever be seen by you.
Example #2: I put $5 in my account, you set your level at $1, you get my email. You don't like my email, you collect $1 from me.
Example #3: I put $5 in my account, you set your level at $1, you get my email. You like my email, so I go on your whitelist.
Simple, really. In theory.
In practice, almost impossible to work.

That site has a shorter and easier to read description of the ideas presented in the paper. The paper is really a technical economics paper, not a mass-market thing. The one-pager is much easier to read, and its the same people.
You are totally right.
I am having to spend $8000 this month to build a new mail server.
Why?
Because 80% of the mail traffic to my system is unsolicited spam and now I need more resources to handle the mail services for my legitimate users because 80% of my resources are dealing with crap.
Because the authorities don't prosecute the spammers, people like me have to pay for the resources they consume even though I didn't invite them to exploit my resources in this manner.
Something needs to be done, and it has to do with enforcement, not figuring out yet another boneheaded way to inject profit motive into the SMTP stream.
