I have an exchange 2007 server installed, with all roles except the edge transport role. This is a simple mail server for a company of 10 people, and we only have one physical server to use for email. I know its not recommended but how do I make it so this exchange server is the only email server and handles incoming and outgoing emails? Incoming email works fine, but outgoing does not work.
From what i've read I need to subscribe it to an edge transport server, which would require another Exchange 2007 License and another physical server. This might be incorrect, but that's where I'm at right now.
I will look into a smtp filter or some other sort of protection for the server once its up and running, but the companies old email server (not windows) crashed and I need to get this email server up asap.
