Just have a quick questions about MX Records needed to set up two different email domains on an Exchange 2010 Server.
We have an SBS 2011 Server with Exchange 2010. At the minute we have a single domain (company.ie) and need to add a second (company.co.uk). Adding the second domain is simple enough. I was just wondering how to setup the MX record for the second domain. We already have one MX (remote.company.ie). We are working on the third party SSL cert also. We are using DNS for the Exchange but will be moving to a Smart Host early in the new year.
Just wondering do I need something like a CNAME record or do I just create a new A Record and MX record and point it to the Public IP of the Exchange Server.
