wsj ed page oddness

Honestly I haven’t read enough of the WSJ’s editorial page to pass judgment, but this article definitely doesn’t fit the picture that had been painted for me by others. It’s a happy dissonance for me, though I do have to say that the headline is really misleading. The casual observer will not take away the same message that someone reading the entire article will.

Oh well… I left this as a draft long enough that TPM already beat me to it.

stuck

I’m stuck and I don’t have a good way out. I’ll paint the picture for you: I’m responsible for a mail server that handles mail for about 50 domains. We get joe jobbed pretty much constantly, and recently spammers have started picking on not-so-tech-savvy individuals who do their mail with us. Eg. “Poor User”<p.user@example.net> gets inundated with bounces. Why?

  1. Spammer forges From: “Poor User” <p.user@example.net>
  2. Spammer sends mail to a misconfigured MTA (not us).
  3. misconfigured MTA accepts the forged mail, realizes the final To: address is invalid.
  4. misconfigured MTA generates a DSN (Delivery Status Notification).
  5. DSN goes to”Poor User” <p.user@example.net>.
  6. Poor User files a ticket with me.

Now, there are circumstances when the original recipient MTA of the spam is not “misconfigured” when it sends the DSN. Example: somebody has set up a mail alias, say joe.user@example.org (note .ORG instead of .NET here), that points to TriLUG mail address, but joe does something silly and kills the TriLUG address without notifying the example.org mail admin. Over the weekend, spam sent to the example.org address will generate bounces.

Anyway, part of the solution would seem to be deploying something like SPF or DKIM. This would cut down on the number of servers that accept mail that claims to be from us but isn’t. Great! Let’s delpoy one of them! But….

    • Suddenly we’re forcing all our (hundreds of) active users to reconfigure their mail clients to use us when sending mail outbound with a From: that claims to be from our domain. That’s a big flood of tickets, given the number of MUAs that aren’t configured that way by default.
    • We don’t do DNS in-house. We’re dependent on $UNIVERSITY for DNS, and they’ve told me flatly they won’t do SPF or DKIM until they’ve finishd migrating to a new IPAM. Oh, and I’m the first person ever to have asked them about either.

    So I’m stuck. I’d welcome any suggestions that will help mitigate the problem. This is a bit of a pickle.

    a coherent argument

    A day of spam evil and various upgrade headaches (not to mention end-of-semester woes) makes this sound downright logical:

    Orange Politics, audio of the call

    That robocall I posted about earlier also got posted on Orange Politics, where it got a lot of reads and a lot of comments fairly quickly. I started a tumblr blog to be able to easily post the audio of the robocall.

    robocall from a realtor

    I just got a robocall from a group calling itself “Citizens for a better Orange County” that opposes the Transfer Tax. It calls the tax the “Home Tax,” which is clearly wrong on two levels. Firstly, the proposed tax is on all land sales, and secondly it is an attempt to falsely personalize this tax for local homeowners. Oh, and it fails to mention an important detail: the tax rate would be 0.4%. That’s right: four tenths of a percent. That’s one thousand dollars on a $250k hypothetical home. Sounds like too much money? Well, what are the alternatives? If this is defeated, the only two alternatives that have been seriously discussed are a sales tax (the most regressive tax possible) and a property tax increase. A property tax increase would be a home tax. Everything about the robocall was misleading and dishonest.

    The call directs people to a website that I won’t link to here. The website refers to “Tom Holt” as their treasurer and “Mark Zimmerman” as their spokesperson. A bit of googling gives:

    Mark Zimmerman (919) 942-9150

    so that might be one way to get more info about this if anyone is interested. The website also lists a toll-free number: 866-275-1129. Also, a visit to the Internet Archive’s Wayback Machine shows us that Mr. Zimmerman was chair of the Chapel Hill/Carrboro Chamber of Commerce in 2005, and is… drumroll… a realtor with Remax.

    So, to recap: a realtor is the spokesperson for a shady group that is using shady tactics (including robocalls and dishonest “home tax” verbiage) to try to shoot down the Transfer Tax. A good question for Mr. Zimmerman might be, “How much money have you personally spent on trying to defeat the Transfer Tax?” Or maybe, “Why do you feel it’s necessary to resort to dishonest tactics to defeat a tax that might have a small impact on your business?”

    voicethread of recent pictures

    Monte is in my Network Protocols class at UNC, and we went out for pizza and beer after class. He started talking about what it is that eats up all his time, and it absolutely blew me away. Check out my feeble attempt to use his website below, or jump right to making your own.

    So… mirroring scripts are having trouble. I’m not a network expert, but this looks slightly problematic.

    changes in the sidebar, COSI calendar

    Most of you get this via planet TriLUG or feedburner, but for those of you that actually visit the site, you’ll notice that I’ve made a bunch of changes to the sidebar recently. The most recent and most important is that I made a page for the COSI calendar. I’m going to get off my rear and actually start planning events and otherwise making sure that COSI continues to be an active group that’s contributing to the Open Source community in one way or another.

    And now, time for Lunch.
