But, that's a rosey concept! John: That happened to us, this week. I was unable to use the SMTP on my web site for somewhere between 48-67 hours, because of Spamhaus. Apparently, this morning, when my wife powered things up, we got a clean IP address. When I went to the Spamhaus web site, it showed the IP numbers clear, but, on other lists. Supposedly, if one uses SMTP Authentication, this problem goes away. However, I have always used SMTP Authentication. I do not want to change to another web hosting ISP, because this problem might follow me. And, I've been with them for almost 6 years. Also, Spamhaus says the problem should go away, in 1 or 2 hours, and in the past that was true, but not this time. Good for you, to want to handle this in a better way for your clients! Lanny
