if you are using postfix like I am, you can set up a list called relay_recipients with all your users in it in this format: [email protected] OK add the line to your postfix main.cf file like this relay_recipient_maps = hash:/etc/postfix/relay_recipients pointing to where ever your file is. Then after you compile the list, run postmap /etc/postfix/relay_recipients run that any time you edit the list. You can pull your AD users and export them to the list also. Follow point 17 of this tutorial: http://www.howtoforge.com/the-perfect-spamsnake-ubuntu-jeos-12.04-lts-precise-pangolin-p4
You can set this to run as a script to keep this list updated and automatically "postmapped". I imagine you can use a similar setup for exim or whatever mail you are using.
