We run a website that has got a news subscribe feature, this subscribe feature sends emails of the news to the subscribers. It works in conjunction with Coldfusion and runs on Windows NT Server and runs Microsoft Exchange. The problem that I want to get over is when people enter an email address incorrectly. If the email that the server automatically sends out bounces back, I want to be automatically notified, so that I can then remove that email from the mailing list. Is there any way that I could be sent this bouncing back email, by the server so that I can achieve this ??
