Networks

In the example "sami@balfakih.com", do you own "balfakih.com" and have publicly hosted DNS records for this domain?

Does this mail currently go to an email provider, and you just want to pull the email from the providers servers, or do you want the Exchange server to receive mail directly from the internet? All popcon seems to do is to set up the former for you. If that's all you want, the Outlook clients can do this themselves. I wouldn't know how to make Exchange do that.
