I`d like to integrate Active Directory (Windows Server 2008r2) users with a Postfix/Dovecot email server (Centos 6.3).
But, from a simple test I've made, I can only have one box per user. I'd like to be able to have more than one email box per user, not an alias, a separate email box. Also I need to have institutional email addresses not linked to AD users.
I've read something about exchange tabs. Do I need to install Exchange between AD and Postfix to manage email boxes?
