  • Internal namespace and external.

    Hi All,

    Need professional advice ->

    1. I am running a Windows 2003 AD enviornment -> ABC.local (not the real)

    2. I have a external domain hosted by ISP ABC.com and they have created a mx record called mx.abc.com

    3.I installed an exchange 2003 in the environment , users are having an email of [email protected]l

    My doubt is how do I get my exchange to point to my external namespace and my users to see [email protected] when sending mails and so on?

    Please advise.

      When you are creating the MX record in Internet, Root DNS Servers would be knowing the mail alias to your domain. In this case abc.local. When ever you are crea ting the MX record, you need to give the external IP address of your exchange server. Normally company's provide the Firewall IP and they open 25 port on this and NAT the same to your internal Exchange Server.

      So From Internet => MX Records => External IP of your exchange => Internal IP of your exchange Server => Interanal SMTP Message routing engine.

      Finally mail come to your mail box.

        and also you can create a recipient policy which can assign abc.com email ID to the users when ever you are creating an user in exchange.
