Hello, everyone.
I'm relatively new to the world of server management. Our current network was set up by the previous IT team, none of which are with the company any more. I had a question about the way our current mail server is set up. We only have one mail server, but we have two different email domain names. For example, we have someone@company1.com and someoneelse@company2.com, and both @company1.com and @company2.com are managed by the same Exchange server. There is only one domain for the computers. I was just wondering how something like this is set up and accomplished, because we are looking to upgrade to Exchange Server 2013 sometime in the next few months.
Also, is there a way that I can confirm that this is in fact how it's set up? Thank you in advance for your help.
