    It can bounce through a bunch of relays anyway.

    MUA -> Local server -> central corporate server -> outbound gateway -> MX as firewall -> delivery server.

    Just that most of these are either internal, or carefully control who can use them for relaying.

    You know what though, you know what the immigrants who were welcomed by the Statue of Liberty did? They stopped at Ellis Island to register and apply for residency.

    And the ancestors of the people who were manning the registration desks at Ellis Island had distributed infected blankets to American Indians, amongst other things. The new ones merely take away jobs and distribute money more efficiently.

    I suggest that you go for as broad a spectrum of skills as possible. Any good administrator should be able to write code, debug applications, set up a network...

    These aren't separate skills, they are part of a spectrum. If you do things right, don't worry about the first job you get. I suggest trying for a small shop where you get to be the jack of all trades. Take it for the first couple of years. Then with _that_ experience, go for a bigger company.

    While you are at it, join your local LUG (or other IT group(s)). If you answer questions regularly and politely, you will have a history on that list. Also, you might be able to find work on that list itself.

  11. Re:Perspectives on Perspectives on Spamhaus's Dilemma · · Score: 1

    That said, I think the best approach is the one used by SpamAssassin, of associating different scores to each of the tests that can be used to distinguish spam from ham. The scores are found using neural networks. While this has the minor disadvantage of requiring the message to be transported to your server (instead of being able to reject it as part of the SMTP transaction), it should have the highest reliability as far as picking spam from ham does. Usually I drop messages with a really high score, store messages with a high score in a separate per-user "Spam" folder and store the rest in the users' regular inbox.

    First off, filtering on the content is wrong. Spam is about CONSENT, not CONTENT. The only possible value you can give for CONSENT is a reputation based on the initial components of the SMTP transaction (the envelope). Client IP, HELO, sender domain, sender address, recipient domain, recipient address. Given that the recipient address (and domain) aren't useful in doing anything other than blocking open relay probes, the only trustworthy way to check for consent is to use the reputation of the client IP.

    If you think that using SA is right, you haven't understood the spam problem.

    Humans actually have more false positives than software. Finding the one false opsitive in a full spam folder is more difficult.

    We don't DROP email. We reject inline in the SMTP transaction. There is no data phase for most SMTP tranactions which we reject . We don't lose mail. Filtering can, and does, lose email.

    The traditional use of a DNSBL was in BGP, and you were expected to block all traffic from that network. Currently that is restricted to SMTP only. Think of it like this "if your IP is in the sbl-xbl, we don't want your email at all" is a 100% spam scoring reputation check.

    Spamhaus method of fighting spam dont stops 3/4 of the spam of the world. Probably graylists, bayesian analisys, and other methods stops far more.

    You obviously don't run a mail server with > 1 user. The sbl-xbl list stops ~ 80% of our spam. That's for a small email service provider, defending only about 75 million email addresses.

    Bayesian doesn't stop spam. It just flags stuff as possible spam. Humans are worse filters than any software. If you have to look for false positives in a spam folder, don't even bother to filter stuff. That is just a waste of CPU cycles.

    On the smaller servers I run, recipient validation handles ~ 50% of the spam, the sbl-xbl stops ~ 80% of the rest, dynamic IP blocks and hostname checks stop the remaining.

    Why not tariff goods from China? Are you in favor of buying goods made by unpaid slaves in Chinese prisons?

    Please do. I want to see electronics become cheaper here (I don't live in the USA).

    The US is going to have to deal with the fact that access to Indian and Chinese markets requires that they also buy from there. And right now, people are cheaper in India and China than in the US.

    Labour is cheap, technology is expensive. Call centre jobs are highly desirable in India. They offer a chance at a lifestyle which was previously enjoyed only by people in senior management. The alternatives to the wages you term as slave labour are worse (A call centre job for 200 USD/mth against a regular, blue collar job for 60 USD/mth, if you can get it, there _is_ a lot of competition. If you are one in a million, there are over a thousand people like you.).

    What I would really like to see is compensatory tariffs imposed by governments globally to compensate for subsidies (including fixed exchange rates). It would work something like this (random numbers):
    1 Yuan should be close to 2 USD now. However, China is holding the rate at 4 Yuan = 1 USD. Hence, there will be a tariff of 200%.
