I'm a newbie, so please bear with me. I am running a server with MS Server 2003 and Exchange. One of the users has recently been unable to receive e-mails from users outside of the domain (and it's hit and miss from with the domain as well). He can send without a problem, and none of the other users are having trouble at all. The received e-mails are appearing on our e-mail providers web-based site, but they are not being sent to our server. Our pop connector seems to be functioning just fine. Does anyone have any suggestions?
