I call BS. I ran sender-callout verification on my primary email server for a while (before I became convinced it was mildly abusive, and stopped) and typically blocked 2-3 spams per day. In fact, I had more FPs than legit spam blocked by that method. > If you didn't send the the email, why bother confirming it? > Aren't you also adding back to the problem? Absolutely I am. If you're going to try to offload your spam filtering to me, I want the process to cause you as much pain as possible (within ethical limits, which is why I won't forward your email > Even if you confirm your email address, that's all that spamarrest is asking > for. If the email address is valid, then it's done its job. Sender callouts will verify addresses without requiring any action from the end user. If you must [ab]use my resources to do your job, please have the common decency to use my (abundant) hardware and software resources rather than my (much more limited) wetware resources. -- Dave Pooser, ACSA Manager of Information Services Alford Media http://www.alfordmedia.com
