One of my customers has two offices.
Each office runs SBS 2003 using Exchange 2003.
Both have their own domain names and can send/recieve mail directly (DNS).
Less than 15 users in total.
Customer has now introduced a single mail address (different to that on either of the SBS domains). MX for the new mail address points to a smarthost.
We need a system that allows the new mail address to be used on both servers.
At the moment I have it working at Office 1 by:
Adding the new email address in AD and making it Primary.
Unticking - automatically update email addresses based on reciepient policy.
Incoming mail is collected by a smart host and forwarded on to the original domain addesss on a per user basis.
Office 2 was set up by a different IT company who added the new domain name to reciepient policies.
They recieve mail by polling the smart host mailboxes using pop.
The setup works but is complicated and confusing to troubleshoot and manage.
I would like suggestions as to a better alternative.
All suggestions appreciated.
