Exchange FQDN Scenario

[kathanon]

I wonder if anyone can help with this scenario.

We have recently registered a new domain name (newdomain.com) and at present, have our A and MX records pointing to our external web hosting company.

Our internal network is set up with the new domain - newdomain.com - however....

At present the virtual SMTP server in Exchange is set with the FQDN of olddomain.com and only receives mail for user@olddomain.com

Email addressed to user@newdomain.com is forwarded by our web hosting company to user@olddomain.com, which is not ideal now. I would like to receive mail for newdomain.com directly into Exchange.

What I was hoping to do, was the following:

1. Change the MX records for newdomain.com to point to Exchange Server

2. Continue receiving the mail for olddomain.com as well

My question regards whether I need separate virtual SMTP servers for each domain. Also if I set up an additional virtual server using newdomain.com as the FQDN, can it use the same IP address and port as the existing virtual server?

I am not sure what the best way to do this is and would welcome some information before I change the MX records.

Many thanks

No you don't need separate virtual SMTP servers, just the additional domain added to the receipient policy. This is what I do since we own .com .net and .org.

Thank you, well that seems a lot simpler, I will add it in recipient policies

At present we have the old FQDN in the virtual server, I am assuming that I just change this to the new name as well.

That works. Or you can keep it, add another, and have both.
