Hi, We have a domain setup couple of years back its something like company.co.uk our HQ has the address company.com and we wish to add support for the .com domain in our server. The company.com has an exchange server and we plan to route mails received from their server to our server. All users should have the company.com address. For this, we plan to add the users on the ex server and say that for these users route mails to smart host which will be our server ip. The smart host should accept mails for company.com this I plan to do so by adding this domain as an alias in my virtual domains. For all users from my sode sending mail I will create smptproutes to point to the ex server. We have more than 5000 users as a whole.
Please provide some input on whether this approach is correct. Any othr solution most welcome. Regards
