James Hess wrote: Preventing hosts from just SMTP'ing out just anywhere they like This sounds great, except it doesn't scale. My router says there is no noticeable difference between tcp/25 and tcp/445, or udp/134 or udp/1434 or tcp/1025, or tcp/80. It asked if we should just block all ports and force people through proxy servers. Why mitigate one vector when you can take them all out? What makes SMTP so special a vector? Yes, my router speaks. Yours doesn't? Jack
