Thank a lot for your reply. Now, it works, what i done : All users (firstorg,2ndcom,thirdnet are members of users) cd /var/www/domains chown -R firstorg www.first.org chown -R 2ndcom www.2nd.com chown -R third.net www.third.net chgrp -R users * chmod -R 745 *
Now, user "2ndcom" can only view, modify only his folder "www.2nd.com" ** And for MTA choice, i will try to install postfix ;-)
