I have exchange 2003 in an AD enviroment. I am trying to send out an e-mail from a POP account (not through exchange just using outlook) I set up in Outlook. I get an error saying 550 relaying mail to ......... not allowed. This happens when I send to any mail address with this POP account. I can recieve mail but can't send. I there a policy setting in exchange I need to set up?
