My company mail server is a QMail on Linux co-located in a data centre. The company has 5 different companies in the group and each one has a minimum of one domain name. In my QMail I have 7 active domain names which works fine. Now my question is if I want to build such a setup in an Exchange Server (2003 or 2007) how should I go about it. Can anyone please suggest me some guide or something to configure exchange server 2007 to handle multiple domains seperately. There may be users who have mail accounts in more than one domain (e.g firstname.lastname@example.org, email@example.com).
I tried searching alot on this subject but couldnt find any absolute q\guide or anything.
Looking forward for your assistance.
