I was actually able to resolve the issue. Basically, since I am using sendmail by masquerading through my isp, an undelivered email bounces to my isp and not to me. Since the login for my local machine is different from that of my isp, my isp does not know to send the bounced email on to me. The way around this problem was to have sendmail rewrite your address using the login for the isp. __________________________________________________ Do You Yahoo!?
