Re: anti-spam vs network abuse

Why is probing networks wrong?

i guess it's a last ditch scaling thing. i won't complain to an isp when their customer probes my host as a result of me sending them e-mail -- but i will drop in a local blackhole route so that i won't get any more traffic from or to the prober's network. (if the isp thinks this is too draconian they are welcome to contact me, which is how jon and i wound up talking a couple of months ago.) on the other hand if they probe my network looking for relays to see whether any of those relays are open, then i will complain to their isp. there's an active prober in asia right now who actually *is* an ISP, though, and so, there's really no basis for discussion. -- Paul Vixie
