DNS MX records
Posted on 2008-10-22
I have an exchange 2003 2 node cluster that I want to take off line. I also have an exchnage 2003 back end server that is online and all of the mail boxes have been transfered to it. As it stands right now I am unable to take the exchange cluster offline because incoming mail (mail from outside of our domain) is not delivered to the back end server when I turn it (exchnage cluster) off. What I need to know is how do I manipulate DNS so that I can leave the currently advertised MX record (cluster node) in place and have mail forwarded to the back end server MX record and ultimately into the appropriate mailstore on the back end exchange server. I know there is a CNAME record involved in this and I have tried a couple of configurations to no avail. Any help will be much appreciated. Remember, I want to be able to turn off the currently advertised Exchange server and still have mail delivered to the unadvertised mail server.
