So I'm thinking that, if joomla is already able to connect to my Exchange Server 2007 and send to me (mailfrom) the system notification, there is only a problem with the configuration related to Recipient (mailto), but don't have idea witch line on Controller.php I'll need to change (and if is on joomla\components\com_mailto or joomla\components\com_contact folder).
