Name and Shame Spam Senders With OpenBSD

Posted by timothy on from the sounds-like-a-cool-infomercial dept.

Peter N. M. Hansteen writes "Once you've identified spam senders, OpenBSD provides all the tools you need to take one step further: exporting their addresses and publishing the evidence. You can even trap them yourself using known bad addresses. It's easy, fun and good netizenship."

  1. the known bad addresses part seems dangerous by Trepidity · · Score: 5, Interesting

    I agree the vast majority of email sent to "known bad" addresses will be sent by spambots, and that'll probably be the exclusive source for never-published addresses. But in the case where they publish these known-bad addresses on a page that they hope spambots will index, it seems blacklisting based on them is vulnerable to abuse. If I want to get some server blacklisted, and I have any sort of access to send mail from it, I can just send mail to the known-bad addresses. For example, good way for mischievous students to cause mayhem by getting their university's mail servers blacklisted.

    I think someone tried the latter approach already and it didn't end up helping her much
