I recently installed Exchange Server 2003 on a Windows 2003 OS. This mailserver is a child domain of a existing PDC. Everything is fine except that I cannot receive mails send from senders inside and outside my network. I can send emails to outside world and people inside my LAN but cannot receive any. The SMTP and POP service both r running fine under Exchange Server System Tasks.
This is my first time on Exchange Server. Can anyone help me which way to proceed to solve this issue. Thanks in advance
