This is the first time I have set up exchange so I am sure I have made some really stupid error and I hoping you can help. I have set up exchange to receive mail using the pop3 connector and send through my ISP smtp server.So in the setup using CEICW under the email delivery method I selected 'forward all email to the server of my ISP' and entered mail.bigpond.com. Under retrieval method I selected only 'Use the Microsoft Connector for POP3 Mailboxes'. I set up the pop3 connector with the details and that must be ok because I can recieve email but when I try to send I get a message from system administrator saying cannot send as the address does not belong to the organisation.
I have not done any port forwarding as I was unsure what to do. I this sounds really novice and probably very stupid but I am very new to servers and especially exchange.
