IETF to Look at Spam
m00nun1t writes "CNET has an article about the Internet Engineering Task Force (IETF) looking at what they can do about spam. According to the article, many of the proposals seems to "require changes in basic e-mail technology", which presumably means SMTP (and about time!). Maybe they are looking beyond just SMTP - anyone have any insights here?"
A man has been jailed for six months after a trainload of commuters saw him having sex with a goat.
Rob Malda, 23, of Kensington Road, Hull, pleaded guilty to one charge of buggery with an animal after the assault on the female goat in August last year.
Sentencing HIV-positive Hall, Judge Michael Mettyear, at Hull Crown Court, described the incident as "bizarre and disgusting". Hall had a previous conviction for indecent assault against a six-year-old girl.
The judge expressed frustration at being unable to order that Hall be banned from working with children in the future, adding: "You have pleaded guilty to buggery with an animal, a goat. It was committed in open air with people about, with people who could see.
"You were acting in an indecent manner, indeed, there was an seven-year-old boy in a position to see, although he was protected by his grandfather."
The court was earlier told how Hall had been returning from his sister's home on August 14 when the assault took place at the Argyle Street allotments.
A seven-year-old boy out walking with his grandfather had witnessed the attack together with a train-load of commuters on board a Hull to Bridlington service that had stopped at nearby signals.
Hall was seen holding on to a belt that had been put around the nanny goat's neck with one hand, while masturbating with the other. He was then seen with his trousers around his ankles having "penetrative sexual intercourse" with the animal.
Forensic tests matched semen taken from Hall's clothing to that found at the scene and samples of the goat's hairs were also found in his underwear.
Reading from the pre-sentence report, Mr Mettyear said Hall had shown evidence of being "preoccupied with sex", having "emotional instability" and problems maintaining relationships. It added that he targets "vulnerable" victims - "a child in the first instance and now an animal".

Almost all spam goes through open relays. To stop spam, stop the open relays.
:/
If all users ran a small script that mailed the last 100 spams they received to the last server they got spam from through the next to last server they got spam from with a return address of the next to next to last server they got spam from then we have real fun.
1. Open relay #1, gets your messages: "Here is some mail for you to relay". Please send these 100 messages to this other open relay #2. Open relay stores and attempts to delivery 100 messages, eatting up its resources.
2. Open relay #2. gets is contacted by open relay #1 100 times. Consuming some resources. It says "I don't have this mailbox." You should tell the sender. So, open relay #1, consumes more resources, making the 100 messages into 100 bounce messages.
3. Open relay #1, now tries to deliver the 100 bounce messages to "the sender", open relay #3.
3. Open relay #3 gets contacted by open relay #1. And consumes some resources responding to 100 "No such user here." Open relay #1 drops the messages.
The point is, spamees, can perform a distributed DOS that shuts down the open relays, by having them talk to each other. After all, the open relays have told the spamees: "Hey, I will try to send mail to anyone: as proof here is some spam for you." The spamee is saying: "Thanks! Here are 100 messages for you to deliver to another open relay that sent me spam."
The only one who really is really penalized are the ISPs who carry the traffic. However, the ISPs who allow open relays on customer networks deserve the traffic and more. Any upstream ISP should not sell service to ISPs who allow open relays...
Hell, send 1000 messages instead of 100 to the open relay. Also, have the servers to contact send bounce messages selected at random. This forces open relay #1 to open 2000 connections.
BTW, the messages looks like this: "Dear postmaster, please do not spam me. You are receiving this messages because you opted into my sent-me-spam mailling list, by sending me spam. Attached is a spam from another list member."

Spam is highly redundant commercial advertisement. And we don't want it. So the basic approach would be to exploit this redundancy to filter from the original message streams. However highly localized approaches like personal mail filters will always fail due to the high variety of spam.
How would your personal mail filter know Japanese or Chinese spam ? Not at all, it would just let the spam mails through.
So we can only solve this problem by a worlwide highly sophisticed effort. And the key component will be again the identification of redundancy.
The idea is to build up redundancy signatures of email messages. The global network of SMTP servers exchange these signatures by a grid orientated P2P network. When the distribution of a special signature is worldwide too high then it's identificated as spam and destroyed everywhere [1]. Note that a distributed annealing algorithm can do this in O(log(log(n)))+theta(n) operations (theta(n) a blotzmann distribution due to the annealing process).
Building up these signatures is a little more complicated, something like MD5 checksum won't be sufficient. After some preparsing we have to project the text into a suitable banach space for further operations. Cleckerson and Allman have proposed an infinite dimensional Lie group for this task, surely any Diffeomorphism group over a Hardy space will do [2]. In this space we can build unique (!) singnatures using a simple frequency domain transformation. However we can't of course exchange an infinite amount of data, so an approximation will have to do it. Reseach any Valdpornik and Rosé has shown that there are decent approximations for this task [3]. So we can use these thing to build up our signatures and the whole stuff works indeed.
However the highly numerical approach requires DSP coprocessors in mail servers. But I think that Intel and AMD will throw in a DSP core to their server processors in a few years anyway, so that's not a big issue.

My regular mailbox has 0 spam mails. My spamprobe account has 756 spam mails.
If everyone simply filtered it out of the way and didn't read it, spam would go away. The only conclusion I can come to on this is that those who do receive spam are people who want to receive spam.
