I have a problem with my exchange server. It all started when my ISP changed my IP address and I had to reconfigure my DNS records and my router configuration to accomodate the chane. Initially my exchange was working fine but all of a sudden all remote mails started bouncing back. We can only send and receive mails locally. We cannot send remote mails but we can receive them. I've checked System administrator to see if there is any peculiarities but there seems to be none. Pls help. __________________________________________________ Do You Yahoo!?
