PortalConfig
Mail notification
Requirement : the postfix daemon must be running on port 25.
Log in as an admin user, go to the "Control Panel", and in the vertical menu on the left, in section "Portal", click on "Portal settings". In the menu on the right, click on "Email Notifications", and then change the email address of the sender (by default it is test@liferay.com, put a real valid email from VUB instead).
