Hi All, I have installed SBS with service pack 3 and Exchange 2000 bundled. I have successfully configured exchange so that inter-office mail can be sent and recieved and on the server I can send e-mail to my ISP. However, when I send a message from one of the client computers to an external address, The message goes but is not recieved at its destination. I then tried to access the Internet Mail Service from with Exchange Administrator but all I can find in the connections tab is an SMTP connector. When I try to install a new Internet Mail Service, I receive an error saying that an Internet Mail Service is already installed on this Server. I can't seem to find it in Administrator though. Please advise as to how I can configure Exchange to forward messages to my ISP's SMTP server. Thanks BIM
