SendMail CTO Sounds Off On Spam and FTC
CowboyRobot writes "Eric Allman takes his well-deserved turn in commenting on the state of spam, the dark future, and the need for intervention.
He calls spam an "arms race" where "in the long run everyone loses (except the arms dealers)."
As you might imagine, he's on our side, and he does a good job of clearly describing the current state of spam, and the possible solutions."
of the do not spam registry that they mention in the article. But it seems like a real pipe dream considering how much trouble there has been getting the do-not-call registry up and running.
Also, most telemarketing is done from in-country because of LD charges. Not so with e-mail. It's pretty hard to enforce US laws on a Taiwan spamhaus.
Ah well, every little voice against spam warms me a little at least.
lysergically yours
I am sorry to tell you that you dont understand the average internet user at all. Installing any such spam filter or tool is well beyond the capability of 95% of the users atleast. Classifying mails as "spam" and "ham" and training the bayes engine and all are good for geeks, but not for the average user.Belive me for this. For him/her, these are just unacceptable solution and spammers exploit this weak point. As long as substantial chunk of users are non-geeks, spammers can flourish.And anti-spam laws are relevent in this context.

Your last paragraph, however, shows that nevertheless you completely don't get it, and, by completely, I mean that you really sound as clueless as can be on the topic of spam.
Let's see how many standard spam-thread replies are required for your two sentences of nonsense at the end.
- SPAM is an arms race - single tools don't work, because eventually they will be beaten, as has happened to ALL tools as yet, including bayesian filters.
- SPAM tools such as you suggest are basically for the 3l337. you are basically saying "spam is not my problem if *I* can avoid it. this is a) antisocial and b) bs, because
...
- your note does not in any way address those billions of dollars of bandwidth wasted before spam gets to your personal box.
- if you stop 99% of spam now, by a rough guesstimate of what the parent article alluded to, you can roughly expect to get 100 times more spam than you currently do in 2.5 years time. ergo, problem not solved.
- you still haven't worked on the issue of spam definition.
In short, any article, post, or message that claims that Product X is an acceptable solution to SPAM just doesn't get it.All you can do is look at the spam industry itself, and ask, "why wouldn't they harvest opt-outs for future spamming?" By opting out, after all, you've just given proof that the email address in question is valuable to you. Why wouldn't they want to take advantage of that piece of information. Do you think spammers suddenly adopt scruples on this point? Given how unscrupulous spammers are in every other aspect of what they do, I think it's absurd to think they treat opt-out lists with any integrity.
That opt-out lists will be abused by spammers is common-sense. I think the burden of proof is on you to show otherwise.
I'm generally "Interesting," "Insightful," and even "Funny" here. What the hell happens to me at parties?
OK, at first you were just the usual whinging slashbot, repeating the "Sendmail is BAD" mantra that people who've never run major mailserver like to parrot. (With the usual complaints, which all sound like "Ford cars must be slow, because the Model T was slow, and they must all be broken, because the Ford Motor Co. has had recalls where they fixed cars for free".)
Then you mentioned "MS Exchange developers" in the same breath as Wietse Venema and Dan Berstein, and finished off by calling Allman a "suit".
You must be a troll, then! Or profoundly, phenomenally ignorant.
If the government would enforce the laws against fraud, deceptive advertising and some of the outwardly criminal schemes advertised via spam by following the money trail, it should put a big dent in the spamming business, perhaps enough that the trailer-court spam king seen on Slashdot lately would have to figure out something else to do.
I do not believe that a "do not spam" law would work; at worst, the law of unintended consequences guarantees we'll end up having to give John Ashcroft a sperm sample to get a license to run a mail server due to the slippery slope of regulation. At best, we'll have an empty law that punishes no one.
Instead we've got Ashcroft forming an American Schutzstuffel to protect us from ourselves, and his big anti-crime initiative is to go after people that make bongs. Gee, I feel safer already.
As long as people willing to commit fraud or other "entrepenuers" feel they can lie, cheat and steal via email with no consequences they will, and someone will be willing to deliver the message for them. Get the seller via the money trail and you stop the spam, and can probably nail the spammer as an accessory as well.
Back in the '80s, all sorts of open forwarding were great ideas. Do you remember having to put someone%domain@att.com because AT&T seemed to have better routing abilities than your local box?
Root access always was a hack, but it is a quick and easy way to get around file permissions. Back before pop/imap when everyone read directly from $MAIL, you needed a way to restrict mail to the user and the sendmail program. Who bothered with complicated groups just for that?
I agree that these justifications have gone the way of the dodo, but anyone who's been around understands where they came from.
I'm not trying to defend how sendmail works today, just to explain why those features are present. Personally, I prefer the old "trust everyone" model for mail than the insanity that we have today, but that isn't realistic. DJB's paranoia is useful thing in these modern times.

One of the things mumblestheclown is pointing out is that the fact that you personally are currently managing to filter out your spam is *not* sufficent evidence to prove that the software you are using will be an effective long-term solution.
The software you're using (however clever it is, however hard it tries to "learn" new types of spam), has easily exploitable flaws. The spammers haven't gotten around to exploiting them because it probably hasn't seemed worth their while--probably not enough people are using the same type of filter yet. But they will, eventually. At which point filters that take a fundamentally new approach will be required. Which the spammers will eventually figure out a way around. Etcetera.
Most spam filters are designed with the goal of filtering out spam that is similar to currently circulating spam; they make no attempt to resist an intelligent person who has spent some time thinking about how to circumvent the filter.
Bayesian filters are no exception here.

"If everyone would just ..."
I hear those words about spam and proposed solutions all the time. But the fact is, and will always remain so, that you cannot get absolutely everyone to do so (whatever that might be).
Consider the first possibility: "if everyone would just stop sending spam". Most of the spam comes from about 200 or so different spam gangs. Most of the rest comes from a few thousand naive victims that try it once or twice, get cut off, and never do it again (and thus losing their investment into the spamware and "list of millions" they paid some spamgang for). Already, 99.999% of internet users do not send spam. A solution that requires getting so close to a percet 100% just isn't possible.
Now for the second possibility: "if everyone would just stop reading the spam and buying from spammers". Spam works because the costs to spam senders is so utterly low, that even sending to every internet user is a lower cost than trying to trim the list down to those few people that really want what the spammers are peddling. This goes along with "just press delete". But it doesn't take much in response for the spammers to actually make a profit from their spam runs. And spammer's for hire are making money even if their clients lose money, so as long as there is a supply of naive vendors who are willing to part with their money to get a spam run in their name, spammers profit. Again, this is a case where closing the gap between 99.99% of people who don't even read the spam and the 100% needed to make spammers and their clients go away, is just not going to happen.
But there is a third possibility: "if everyone would stop using ISPs that permit spam". If even so much as 50% of users who are using ISPs that permit spamming were to cancel and switch to a better ISP that doesn't, that would definitely have a substantial effect on that ISP. I bet even 10% would get noticed, although I think a bit more, like 25%, might be needed to get some of the worst ISPs to act. Of course many people do whine about things like "there is only one ISP here" (not anywhere near 50% face this problem) and "it costs me money to switch" (it costs the victims of spammers even more money for you to continue to support an ISP that is able to give you a discount by accepting pink money from spammers). If we were to simply identify the top 10 worst ISPs for permitting spam to come from or through their network, and get a whopping 25% to 50% of their customers to leave (preferring to go to the top 10 best ISPs for not permitting any spam in or out), this would make a substantial impact and cause some CFOs to panic. And this doesn't require anywhere near 99% to be a successful anti-spam campaign.
The above campaign can also be pushed harder if many of us refused to accept email from those ISPs (and thus anyone in their network) as a sort of boycott against spam support. Of course there will be whiners here, too saying "You have no right to block my email since I don't send spam" (but if they are supporting a spammer anyway, guess what).
My whole point is that we need to avoid any "solutions" that make it necessary for absolutely everyone to do something. There will be plenty of people that won't. Instead, the solutions we need are the ones which only require a practical number of people to take that action. If you don't like the ones I propose, then propose your own and say how many people would have to act to make it work.
now we need to go OSS in diesel cars
