FTC vs. Open SMTP Relays

HighOrbit writes "Cnet reports on news.com.com that The U.S. Federal Trade Commission, several state Attorneys General, and Australia, Canada and Japan are sending this letter (pdf) to operators of open relay mail servers to educate them on the dangers of open relays and how they help spread spam. Although the letter does not threaten direct law enforcement action, it does let open relayers know that they have been noticed and warned. The threat of being blacklisted has not worked yet, so will this finally convince mail server admins to shut down those open relays?"

    I remember (fondly) a few years ago when open SMTP relays were still considered a standard setup and not a major security risk. The FTC is definitely doing the right thing in alerting admins to the risks they are taking and helping them to learn how to better protect their infrastructure, as well as the burden it inevitably places on the rest of the internet community when a spammer eventually finds their open relay and shares it with others. Kudos...

    I think that the open relay problem requires a multi-facited approach. IMHO, the open relays break down into several categories that require different solutions.

    1. Legitimate mail servers that are open because of old software installs that haven't been updated, perhaps because that's a low priority. Here, education is a good first step, but threatening to blacklist them and actually following through if necessary will do the trick.

    2. Legitimate mail servers that are open because they're running very old software that's difficult to patch because of its age. Here, the admin may know that there's a problem, but he or she doesn't have the time to dig around for hard-to-find fixes, and retiring the old machine might not be an immediate option. MAPS has a good idea with its list of patches for various MTAs. I tended to get more successful communications with admins when I told them that MAPS had these resources for them to use. FYI, here's the link.

    http://www.mail-abuse.org/tsi/ar-fix.html

    3. Machines that are running MTAs but aren't an organization's real mail servers. These would be around because someone did an OS install that didn't really need a mail server, but they put it in anyway, then promptly forgot about it. They may not even know what they did. In this case, blacklisting that server doesn't mean much. Whoever administers the official mail servers could care less because that isn't a machine that is their official server, so why should they care? This could be a problem in a large organization, where you may have a bunch of uninformed bozos setting these things up faster than you can blacklist them. In this case, the only way to get results is to just blacklist the organization's entire IP space. Yes, I know that this would impact the real mail servers, which may be secure, but it'd also get the admins to take note and apply a clue-stick to the ones throwing insecure machines onto the network.

    4. Servers with admins who don't speak English. Having informative material available in different languages would be a good thing. The Chinese admin you e-mail might actually care about the problem if he could understand the issue a little better. If nothing else, having the info in various languages negates the argument that these admins don't have resources to fall back on.

    5. Servers on networks where the admins just don't give a damn. We've discussed this on Slashdot before, especially regarding Korean and Chinese networks that are getting blanket-blacklisted. I hate to see siginifican't chunks of the Internet being walled off, but if that's what it takes, then so be it.
