I have a windows 2008 server which is the DC and MS 2010 Exchange Server. The AD domain name is abc.net, but the email domains i wish to host are 123.com and xzy.com. I have setup separate OU's and UPN suffixes in the AD for 123.com and xyz.com and also created two accepted domains in EMC and set up rules. I am a bit confused with the way I need to setup the MX records. When I navigate to my DNS Server -> Forward Lookup Zones, i only see abc.net and the A record for it. When i try to create new A records, MX records or CNAME it all points only to abc.net. What is the correct way to setup the A, MX and CNAMEs for 123.com and xyz.com
Thanks
