Exchange Server and DNS - Point old company name to new company
Posted on 2011-03-10
Our company bought another company recently and we are to the stage that we are going to shut down their mail server and we would like to have all mail for the old mail domain to come to our mail server and be processed correctly. For the sake of making this easier:
a.com = Our company with existing Exchange Server 2003 Enterprise Edition on Windows 2003 Standard Edition server. DNS on Windows 2003 Standard Edition Domain Controller.
b. com = Company we bought.
What I have already done:
1) Contacted my external DNS provider and had b.com mail pointed to my mail server address.
What I need to do:
1) Make the DNS and Exchange Server entries necessary to bring this mail in.
2) We have gone to the individuals that used to work for b.com and manually added a email@example.com address in their individual accounts so we don't have and don't want to make policy changes that would give everyone in our orginization b.com addresses.
3) On my current Exchange server my connector brings all mail inside, it is not domain specific.
