Perfect Server - Ubuntu 15.04 (Vivid Vervet) with Apache, PHP, MySQL, PureFTPD, BIND, Postfix, Dovecot Ispconfig. I have /var/www/clients/client0/domain.eu/web and /var/www/domain.eu/web what is the difference since the domains are the same.
Both are symlinks for easier shell navigation and point to the real directory /that Florian referred to) /var/www/clients/client0/webID/web
