Hello everyone --
A quick explanation about my mail environment ... I have Postfix/Dovecot authenticating off of Microsoft AD forest for multiple domains. The actual mail accounts and addresses are the same as the AD accounts -- for example, user1@corpdomain.local. The routable email addresses are domain aliases -- for example, user1@corpdomain.net from the outside internet, and user1@corpdomain.net/user1@corpdomain.local for internal use.
I currently have Postfix setup for virtual domains (specified in /etc/postfix/vhosts) and virtual mailboxes (in /home/vmail). For the user/account/mailbox aliases, I have a MySQL database that maps using a series of SQL queries. The relevant MySQL database table is called 'alias_domain', which has two columns of interest: 'alias_domain' and 'target_domain' -- alias_domain being the external domain, target_domain being the internal Active Directory domain.
My issue is that when the users log into Roundcube with their AD user/pass, the default email address that is setup in their identity is the same as their login -- for example, user1@corpdomain.local. I would like to configure Roundcube so that it supplies the alias domain to each user's account, same as I have setup in Postfix -- for example, corpdomain.local -> corpdomain.net.
While great people, my users aren't exactly the most reliable or responsible when making simple changes to their own settings. Possibly there is a setting within Roundcube that I can change, or maybe a PHP file that can be modified to achieve this functionality?
It's been a long day, so hopefully I have described my situation properly. Any help or suggestions will be greatly appreciated. Thanks!
