We have an Exchange Server that we host at our company. We have many sub-divisions in our firm through mergers, etc. Recently we added a new email Domain to our company.
The server name for out mail is mx1.sixls.com. We added a new DOMAIN for mail named lipmanproduce.com. "In the World" outside DNS we placed a MX record that directs lipmanproduce.com mail to our mx1.sixls.com mail server. The problem we are having now is that some of our employes are having their mail bounced by recieving mail servers because they are looking back at the mail server and seeing mx1.sixls.com and not a lipmanproduce.com name. What do I have to do to properly add the DNS (and where) so that recieving mail servers will accept the mail from our mail server.?
I have a pic attached as well.
