I just got a project and I need help. I recently install two servers, one is my DC and the other is an exchange. Everything is workin, so now I need to configure the exchange server to retrieve and send email from the company. I have read most of the forum and found that you need to open port 25 and then call your ISP to forward your xm record to your public IP. Also that you need to nate your public IP to your Internal IP. Now my situation is that I do not have Nate on my Linksys router, what can I do to get the exchange server to work?
If you can give me a step by step to configure the email server, thank you.
