*
* $mailer = \OC::$server->getMailer();
* $message = $mailer->createMessage();
* $message->setSubject('Your Subject');
* $message->setFrom(array('cloud@domain.org' => 'ownCloud Notifier');

* $message->setBody('The message text');
* $mailer->send($message);
*
* This message can then be passed to send() of \OC\Mail\Mailer
