Tweaking the CAN-SPAM Act

rbochan writes "The Register is reporting that the U.S. Federal Trade Commission is consulting on proposed changes to the CAN-SPAM Act. Changes would include clarifying the definitions of the terms person and sender, and altering the time allowed for a sender to to honor an opt-out request. The FTC proposal is available as a PDF on the official FTC site." From the article: "Critics have accused the Act of being narrow and weak, accusations that may be hard to deny given that the US sends more spam than any other, according to a recent report by anti-virus firm Sophos."

Soviet Five-Year Plans didn't work.

        Market-based solutions that look like "I'll accept your email if you attach a micropayment of X cents on it" can work quite well, because they capture the fundamental economic value, which is the recipient's time, and let the recipient charge whatever price the market will bear for it. Unfortunately, they also attract the usual checkbox-responses of "Users hate these things and will never accept them", and there aren't any really good anonymity-preserving micropayment systems out there, partly because it's a difficult problem and partly because of government interference.

We would normally suspect government proposals to do anything effective about spam to be really motivated by a desire to interfere with free speech, except that any of us who've run for office know that politicians are more strongly motivated by a desire to Look Good, and Look Like They're Leaders, so just it's incompetence (malice is the Executive Branch's job), and even the Great Firewall of China which is designed to interfere with free speech doesn't bother blocking spam.

    The key point that IS true is that spam will exist as long as stupid people buy stuff from spam in sufficient quantity. Short of improving education and waiting 30 years, the only solution is to keep the spam from getting to most users.

    Here's what we really need:
    1) Improved server-client spam communication. This is whatwe don't have:
    1A. An open standard "spam points" header system - so that IF your receiving mail server has a "ranking" filter that gives a point score to emails it can pass an email to your mail client but tell the mail client "this is 75% spam" This lets you run advanced server-maintained filters but make user-specific decisions about how "strictly" to interpret them. Mail clients already by default ignore extra headers, so all I'm suggesting is that the server filters need to add it in a standard way for the clients to use if they so choose. For bonus points, it should have the main header and "this is 90% from a misDNSed mail server." etc. Mail clients should by default have a fairly strict checking, because the users who don't know how to set it are the same users who are likely to be phished.

    1B. An open standard for the mail client telling the receiving mail server "my user thinks message 232432432 was spam" Obviously, users are wrong sometimes, but this would let users who find spam automatically report it to automatically improve their server-side filters. Many servers will ignore this feature, which is fine. But as long as all the clients try in the same way, at least it will be easy for a server to account for it.

    2. SPF & friends - letting at least some servers prove who they are. This exists, although of course adoption could be better. If sender and receiver have SPF, people can't pretend to be you anymore.

    3. Good, tracking weighted server side filters. These already exist. It should let through email that fails only a couple of tests, but should assign a point value based on many factors. Note that we don't need to force everyone to do this, just a the few biggest targets.

    3A. They should take into account use of SPF, whether the maildomain has a valid DNS and some valid RDNS, whether the netblock is commonly used for spam, how long the domain has been active and normal content filtering of the message & content. Netcraft's phishing list, etc.

    You can safely use things like the RBL this way, as long as you only assign a limited weight to them. In plain English, being on the RBL doesn't mean you're a spammer, but it does make it somewhat more likely. You only reject messages that have a lot of clues.

    3B. It should _also_ take into account the current volume of identical or nearly identical messages. I suspect that a worldwide system for IMMEDIATELY sharing a hash of messages that occur in large volume would be helpful; I know some private companies already use a similar system.

    3C. It should _also_ take into account the past history of the IP, rDNS domain, and netblock. This includes the past history of the stuff above and also the past history of user reports as mentioned in 1B.

    3D. A valid tactic for certain kinds of messages is to slow down the processing of them. So if you get something you think is probably spam, you can delay a few minutes and see if its score gets better or worse. It will get worse, for instance, if you find you have a lot of identical messages, but that was the first one.

    3E. Good servers should have a user-specifiable point cutoff.

Modern Internet and computer technology means that it's nearly free to communicate with the billion-or-so people who've got the most money, and the percentage of those people who are suckers has not significantly improved since P.T.Barnum measured their birth rate, and the percentage who are greedy enough to want to exploit them hasn't gone down much either. (That's not to say that the greedy people and the suckers don't overlap - they're just not the ones who make up most of Spamhaus's Top 200 Spammers list, and in fact they're often the best customers for the spamware vendors.) So the economics are there to make spamming look profitable, and often to actually be profitable, the people who want to profit from it are willing and able, and at least a few of them are creative enough to find workarounds for most laws, even if it means setting up an occasional $100 disposable corporation or paying extra for a bullet-proof Chinese website or renting an expendable army of zombies.

    spammers are sending mail from outside of California, so they're not subject to California jurisdiction;
    If you send advertising into California, are subject to California law. See Panavision v. Topen 141 F.3d 1316, 1320),. Burger King 471 U.S. at 475, and Calder v. Jones 465 U.S. 783.

    Before I try going to the post office and getting a glazed look from a postal grunt, does anyone know of a way to block all "Resident" mail, a complete opt-out of litter mills that don't even know my name?
    The short answer is that it's not possible without a lot of effort on your part, perhaps more time than you spend filtering through the mail. The long answer is that you can cut junk mail to a trickle if you're willing to take the time. See Stopping Junk Postal Mail and ignore the Adwords on the right side, they're trying to charge $30 for mostly the same info.
