That's right. It stops the practice of using a sacrificial account, from AOL or netcom, to spam for a web-site that is otherwise protected. Does it make a difference that they didn't spam from their own ISP? That customer is *still* a spammer whether they did it from your site or not. Maybe you're of the "It's alright as long as they don't do it here" crowd? Well, that's one of the things that the RBL was built for. The rest of us don't have to put up with your negligence.
I don't see it as "it's alright as long as they don't do it here". I see it as "I have control over my network, but not over anyone elses". I have an AUP that specifically states spamming is not allowed. I have kicked off users who have spammed. However, I do not have an AUP that says "If you ever spam anyone ever in the world on any network anywhere I will disconnect whatever service you have". I don't control the entire internet, just my little piece of it. :-) Sheryl Chapin Senior Network Engineer CommTel Internet 207.377.3508 Winthrop, Maine schapin@ctel.net
