Name and Shame Spam Senders With OpenBSD

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."

Really?

Really is spam that big of a problem anymore? Ever since I've switched to Gmail all my spam has been blocked by it or blocked by a simple mail filter. Now then again, I don't give my real e-mail address to everyone and their brother, but individual spam blockers have come a long, long ways.

I could be misreading, but I think he's using the IP of the server that actually connects to his server and attempts to deliver mail, not the IP reported in the mail headers.

You're an idiot.

Wow you're an idiot and you don't understand email. He's using the TARGET address to blacklist the IP ADDRESS from the SMTP CONNECTION. That's the envelope sender, not the mail header's return address.

Do your research before you start casting wild allegations around.

You don't get spam because of a combination of anti-spam techniques similar to this one. We have to keep developing them, or else the spammers will get ahead.

YOU may not have much of a spam problem, but mail admins everywhere - including google's - most certainly do.
