You're proposing revoking a server's certificate for spamming. Based on what level? What level of fault? Would Gmail get its certificate revoked because 1% of the email it sends is spam? > I'm just proposing a system that allows the identification of organisations > that inject and relay spam. That then allows enforcement of accountability. We can already do this via IP addresses and sender domains and SPF/DKIM authentication. Yes, its just a proxy and sometimes its wrong, but it works fairly well. >> How about spam sent from a hijacked account?

Do you know how many spam messages are sent a day? How large an enforcement organization do you propose to go after them all? And how long do you think that would take? Not to mention that multiple people and governments have different definitions of spam. When we see a new spam campaign, we need to be able to shut it down in less than hours. A recent time that we helped the US government go after a malware operation, it took them a year before the first arrests. A year where we had to leave the botnets and operations alone so they could gather the evidence necessary to make the arrests. Police action doesn't scale the same way that spammers do. >> Or how much money do you think a spammer is willing to spend to buy an >> account, even on a free service?

Weee, now we're talking about extra-governmental authorities making the rules. Its always great to argue with an RBL maintainer about whether or not something is spam. Or maybe what you're proposing is more like SOPA/PIPA, we can have an organization like the RIAA deciding what's good. Even better, the government of Iran can just prevent their providers from accepting any mail certified by other governments. Or here's an even more fun one: We just emailed all of our users about the changes to our privacy policy, a move we made at the request of the US government. And we had RBL organizations complaining that it was spam. Who wins? Our answer is simple: the user decides what is spam, not someone else. Our job is to make our spam filter match each user's expectations. > Revokation of certificates would be a function of government after due > process.

Not as much as you'd think, turns out spam is much smaller than regular mail at this point, at least for consumers. A large percentage of mail, but on the order of 40x smaller in size (on average). And email in general is not generally a large user of network capacity. How many email messages, even at 100k average, does it take to equal a single iphone app download? Or a streamed video from Youtube? > How many opportunities are lost due to false > positives? Personally I believe the real economic costs of spam are > astronomical.

Regardless of those costs, your proposal would cost more and still not solve the problem. > Otherwise we should just all join FB and just use that for communication and > ditch mail altogether. We have the stats on what percentage of our users receiving mail mark messages as spam or not spam. Its tiny. For most people, they don't see the spam, and maybe they don't see enough to actually check their spam label, but its just not an issue. As to where the kids are going these days, who knows. Email is certainly not the only game in town. Brandon _______________________________________________ imap5 mailing list [email protected] https://www.ietf.org/mailman/listinfo/imap5
