  1. Re:Too drastic? on Earthlink Deploying Challenge-Response Anti-Spam System · · Score: 1
    How quickly will all of these vendors conform to Earthlink's new technology and make the needed changes in their automated systems?


    Why should they bother? I don't see any "Here's how to send to Earthlink" RFC. Suppose I order something online and request an email confirmation, delivery status, etc. and then I reject all those messages. Whose fault is that. The business? NO! They sent the message as requested. Making matters worse I may in one step be requesting a receipt from the business and delivery updates from a separate shipping company. Of course people will most likely start bitching at the company - "where's my receipt?" and rejecting those responses as well.


    I hate spam, too (I reject 55% of general inbound mail to my server) but I don't think this is the ultimate solution.


    The answer to solving SPAM resides in the current mechanisms used for the actual transmission and delivery


    Here, here! If the biggies (Earthlink, AOL, Hotmail, MSN, etc.) enforced best practices, for example reject all mail where the EHLO is not FQDN, resolvable and the primary name of the sending machine (per the RFCs) and verified by DNS check to match the connecting IP there would be a massive cleanup of misconfigured mailservers and the rest of us could add the same rejections. This has to be done by the big guys. Unfortunately operators of smaller domains have no clout in requesting repair of BigCo's screwed up server but if lots of their mail got rejected they would fix the problems (marketing or the CEO would make sure of it).


    Strict adherance to best practices would go a long way toward denying the vermin the dark hiding places they crave and force them into the light where they can be squashed.

  3. Re:Why does filtering work for me? on Spam Lawsuit Clearinghouses? · · Score: 2, Interesting

    Probably because you don't have screaming customers. It's one thing to filter mail for you or a small group of understanding people. It's quite another to deal with a large customer base.

    One batch wants all the newsletters from {fill in favorite hobby/group} but that mass mailer is blacklisted because they got an unscrubbed list from an unrelated client.

    Meanwhile the small business person is afraid that they really might miss the "BIG $1,000,000 ORDER!!!"

    A friend of mine is researching anti-spam for her company. Of course the PHBs require no false positives, quarantine everything evil for review, customize on a per user basis, etc. Outsourcing this to an ASP will probably cost them $15k+/year.

    What is AOL rejecting? Something like 1 billion messages every day and that only represents a fraction of the spam they get. Even a false positive of 1 per thousand rejects means 1,000,000 legit emails rejected every day. They have to be very careful.

    It's way easier blaming the spammers than explaining why you rejected the legit message a customer/boss needed.

    Then again look at the source...big companies who don't believe the RFCs apply to them anyway (postmaster is a required address that must go to a live person not an autoresponder but just try to reach postmaster at aol/hotmail/yahoo).

  4. Try local on Finding Decent Unix Server Hosting? · · Score: 3, Insightful

    Check your local area - I'm quite happy with my local ISP, lmi.net. They are very geek friendly (run a server? no problem. NAT? we don't care. Blocked ports? no. Static IP? that's all we offer...) but without customers the locals will disappear.

    If you don't have a local ISP that meets your needs try Pair (pair.com host of Tom's Hardware, Perl Review, etc.) or Hurricane Electric (he.net). I don't use either but have heard some good comments about both.

  5. Technical Pressure on AOL, MS & Yahoo Unite On Anti-Spam Initiative · · Score: 4, Insightful

    One thing that the big ISPs could do is exert technical pressure to help deny spammers the ability to hide. I would love to see them reject all mail in which the HELO greeting is not fully qualified and resolvable (as required by the RFCs). Same thing everywhere else a domain appears in an SMTP conversation. This would force a mass cleanup of incorrectly configured mailservers and I would be able once again to include that as a requirement on my server.

    Although perhaps exceeding the requirements of the RFCs, they might also consider refusing mail if the HELO/EHLO does not resolve back to the connecting IP.

    In addition, they could publish via DNS info records or ?? the IPs of all their outbound mail servers (no MX won't work - that's only for inbound mail). It would be great to be able to bounce all mail "from" someone at yahoo/hotmail/aol/etc. unless the connection came from a mailserver associated with that email address (sure, for some people the mail may have been legitimately relayed before arriving at their site but that has never been the case for my servers).

  7. Follow the current rules on The Case for Rebuilding The Internet From Scratch · · Score: 4, Insightful

    Before running off to change everything how about just getting people to follow the rules we have.

    For example one requirement of the SMTP RFCs is that everywhere a domain appears in an SMTP conversation it must be fully qualified AND it must resolve. Unfortunately that requirement is rather widely ignored. Just set your mailserver to reject EHLO/HELO greetings that don't conform and you will bounce lots of spam as well as tons of legit email.

    Like the cockroaches they are, spammers rely on hiding in shadows. If legit mail-server operators stuck to the RFCs detecting, filtering and tracking the shady ones out would be easier.

    No, it's not perfect, but at least I could do things like check the EHLO against the connecting IP to see if the other server is lying.

    I would be absolutely delighted if AOL, Earthlink, Hotmail, Yahoo, MSN and other large mail handlers started being very RFC picky in what they allow. This would force a mass cleanup of non-compliant servers and would make my job a lot easier.

    In a former job we totally hammered an app on our internal lan and got many times the requests rate we would need in the real world.

    Fat, dumb and happy we figured that the real world couldn't hammer us as hard as we could internally. Wrong! Slow connections require maintaining connection resources much longer than on an internal network where the response can be created and dispensed with almost instantly.

    When an expert reviewed the situation they found that she could quit. The IRS was taking a huge chunk of the incremental income and all the extra expenses made necessary by both of them working (more car usage, clothing expense, child care, housekeeping, eating out, etc.) ate what was left.

    The wife on that show broke down in tears - both in joy that she could finally stay home with their kid like she wanted and anger/sadness that they hadn't known that she could have all along.

  16. The Law on The Ethics of Stealing Wireless Bandwidth? · · Score: 1

    IANAL. That being said, In California, section 498 of the Penal Code makes theft of utility services illegal. Whether the law would apply in an individual case seems to depend on lots of things (who owns the router/bridge, who knew about the access, "intent", etc.) but it appears that you could get into criminal trouble.

    I used to work at a campus police department. We had regular problems with a street-person cranking up his boom-box in a campus parking structure late at night and annoying all the neighbors. After numberous warnings the officers just started arresting him for theft of electricity for plugging into the campus owned outlet in the structure. No, it wasn't locked - it is just an outlet. That doesn't make it legal to run a cord from it over to your apartment.

    Another consideration - what if you use an "open" wireless point. Would you be offended to find the owner of that access point was logging all your traffic and using it for whatever purpose he chose? You "plugged" into someone else's network so I don't think you have any expectation of privacy.

    Here's the law (partial - there's lots more boring stuff) on theft of utilities. (Yes, telecommunication is included in the definition of utility):

    utility services without paying the full lawful charge therefor, or

    (1) Diverts or causes to be diverted utility services, by any
    means whatsoever.
    (2) Prevents any utility meter, or other device used in

    diversion, tampering, or unauthorized connection existed at the time
    of that use, or that the use or receipt was otherwise without the

    the following objects, circumstances, or conditions on premises
    controlled by the customer or by the person using or receiving the
    direct benefit of all or a portion of utility services obtained in

They also run on 9V batteries which is ideal for me since once a year I go around and change the 9V batteries in my smoke detectors, water alarm, alarm-clock backup, etc. The batteries still have substantial life left and the PALlight about the only place I can use them. Of course the batteries last so long that it's almost impossible to use up even my used batteries. The PALlights also feature a couple of brightness modes and a strobe mode.

    Where I live in California I don't need to worry about the water heater freezing.

    Yeah, I had that crazy idea when I built my house, too. I'd fix it up and that would be that. It just ain't going to happen.

    My place is a plain old post-war home that is about 55 years old and is structurally fine but I have had to do many upgrades to it. With maintenance it should last a very long time but at some point it will probably be more economical to flatten it and build something new.

    The fact is that tastes and technology change. When I moved in the place had knob and tube wiring and no insulation at all. I rewired (hint: use 20 amp, not 15, and run plenty of circuits - I have every one of my 7 outlets in the kitchen on its own breaker - no problem with overloads here). I had insulation put in. The plumbing was updated to copper years before I moved in.

    At some point I will need a new furnace (40+ years old) and a new water heater (16+ years old) and will look into the new energy-efficient technology for those.

    The point is that the house was pretty much state-of-the art when built but as things wear out or technology changes then the place gets upgraded to newer standards. What's next? Who knows? I could have pulled lots of cat 5 and then wanted cat 6 or fiber. A friend did a full network wiring during a remodel and never used it - by the time she was done she and her husband had switched to wireless. Even my nice wiring upgrade may become obsolete with DC feeds and smart controls. Someday I may be using fuel cells and heating the place with the waste heat. I don't know. Stonehenge has lasted a long time but it doesn't have any modern upgrades.
