Have you checked out NiX Spam?

Marcel Lohmann, one of the admins behind the NiX Spam DNSBL, reached out to me to ask me if I would review this DNSBL. I haven't published any new blacklist reviews in a couple of years (and that's not likely to change any time soon), but I am happy to link to his Spamhunter blog post that talks about why you should consider using the NiX Spam DNSBL.

What say you, good readers? Do any of you use this DNSBL? What do you think of it?


  1. I've been eyeballing this one, I like the idea but haven't had the time to do a proper analysis.

    I do know that it would hit nearly 50% of the younger-than-24-hour not-already-flagged-as-spam spam in one spamtrap right now so that alone justifies further investigation.

    I'm more concerned about false positive rates, so pulling a list of IPs that have sent wanted mail and running it against NiX over the course of several days (due to the rapid listing/delisting) will be the next step.

    Due to the extremely dynamic nature of NiX reviewing performance against spam more than a few minutes old is probably not going to give as useful results as a real world test.

    All in all it certainly looks like there is some potential here.
