Among the speakers are: Paul Graham (of "a plan for spam" fame), ESR, John Graham-Cumming (of "POPFile" fame), and Matt Sergeant from MessageLabs. According to the homepage, this conference will be very informal: "no fees, sponsorships, proceedings, luncheons, contests, etc. Just a series of quick, concentrated talks, and then we all go off and get Chinese food." Slashdotters who are peeved about spam can register here."

      Well that is pretty much how conferences start. They begin as a technical session with 5 experts talking and 50 people in the audience, then the next year there are more people and the program gets longer. The year after that there is an exhibition which the year after becomes an exhibition floor. After that the whole thing goes downhill and turns into a trade show.

      That is exactly how the RSA Conference and Interop began.

      I am somewhat disappointed by the means of choosing the papers, basically the first people to propose a talk. As a result the spam conference will only be discussing filtering approaches based on identifying the spam. The alternative approaches based on authenticating the genuine signal simply won't get a hearing.

      The problem with filtering approaches is that they only work as long as the attacker does not have access to the filter. If the attacker does have access to the filter they can repeatedly test and modify their spam until it gets through. That is why the filtering built into Outlook fails, the attackers have access to the filter and can use countermeasures.

      Filtering techniques are a hacker solution, they only solve the problem for the small community of hackers that use them. Once they are used generally they fail.

I don't care about the bandwidth issues; doesn't affect my home connection much, and doesn't affect my server's connection at all. It's my time.

      My solution? Well, I haven't found a perfect solution, but (given that bandwidth isn't my main concert) Mozilla's bayessian (sp?) filtering is working well so far. Hopefully the next major Moz release will handle this better.

      Currently (1.3a) it marks SPAM as "Junk" mail automatically. After only a few days it easily recognized SPAM. After a week there have been NO false positives. After 2 weeks it seems to be dead-on accurate.

      Hopefully the next Moz release will let me do more with it (such as NOT playing my "New Mail" sound, marking them read, moving them to a Junk folder, etc). So far 1.3a is showing serious promise, at least in the filtering part. It uses Bayessian filtering (based on the Plan for Spam article linked above -- a good read if you haven't seen it), and is quite good so far. I would personally be happy if, using the Mozilla current implementation, I could never see mail Mozilla sees as "Junk" mail.

      My point was simply that for me, bandwidth isn't the problem -- and I run several (not open-relay) mail servers -- rather, the problem is the time I spend manually filtering SPAM from real mail (running several domains). Bayessian filtering is perfect, as it's based on the individual user. It's what got me to try Mozilla mail again in the first place (first time since M12), and already, just having it mark them as "Junk", it's saved me a ton of time.

      Mozilla mail, OTOH (version 1.3a) with Bayesian filtering has been flawless. The first few days I tried it, it had a few false positives. After a week, no false positives but a couple missed SPAMs. Now (a month later) it seems to be about 100% accurate. Because it learns what *I* consider to be SPAM, and only I.

      It's so simple it's pathetic. See the "Plan for Spam" link, it's a good read if you haven't read it. Now, hopefully the next Moz release will actually mark the Spam as "read", and move it to a "Junk" folder (now it only marks it as Junk -- it still plays the new mail notification, etc). I would trust it to move my SPAM to a Junk folder, where perhaps once a day I would verifiy that no false positives were found. After a while, I'd probably just trust it's judgement.

      Key being that it's based on *you* -- it finds word patterns in what you consider to be SPAM, and bases it on noone else's judgement; it's completely personalized, and IMO the only solution (as far as client-side filtering goes anyway). For me, it's the solution I've been looking for. Now I just hope the Moz team completes the feature nicely (which I trust they will).

If you're a human being, you either reply to the confirmation request (if the message was important) or you ignore it (if the message wasn't important, in which case I'm happy not to hear from you).

    The only problem is those damn Nigerian bank scammers. They actually read their replies. i've heard from two of them in the six or seven months I've been running this whitelist contraption.

But, I'm so glad to be free of spam... Every time I check my email and find no spam, it feels like victory.

      I don't claim that it's a permanent solution (hence the note about "for now"), but "fundamentally broken" radically overstates the magnitude of the trivial potential problem that you bring up.

      First, the human problem: When one bit of spam gets through the whitelist, the spam victim removes the 'from' address from the whitelist, and the spammer needs to find or create a new whitelisted address for each of the million+ target addresses. It wouldn't be enough to sell CDs with millions of addresses, they would need to be address pairs (one target address, one or more whitelisted 'from' address). While destination email addresses are long-lived, the whitelisted addresses would be shortlived and all but useless.

      Then there's the technical problem: most spam is sent with a single 'from' address and multiple 'rcpt to' addresses. This is how relay abuse gets done - the message data gets transmitted once (or relatively few times) with MANY recipient addresses, so as to reduce the spammer's need for bandwidth. (It fucks over the relay owner, but who do spammers care?) Sending large amounts of spam with from addresses customized on a per-recipient basis would require spammers to acquire and maintain huge amounts of bandwidth - an amount roughly equal to the amount that they currently steal. Possible, but unlikely.

      Call it "fundamentally broken" if you wish, but the bottom line is the signal:noise ratio in my inbox... it's approaching NaN. That makes me happy.

      Yes, spammers can pretend to be whoever they want, but that takes work, and spammers and fundamentally lazy, so I'm not worried.

      If whitelisting catches on in a very big way, spammers might start working on ways to get around it, and if they have any significant success I will to what it takes to stay one step ahead of them in the inbox arms race. But if whitelisting doesn't, spammers won't, and I'll continue to ignore the spam problem while I enjoy my spam-free inbox.
