Sending Email via CakePHP's Email component

Hi! I am not able to send messages via the email component of cakephp. I used the cookbook's code:

$this->Email->from    = 'Somebody ';
$this->Email->to      = 'Somebody Else ';
$this->Email->subject = 'Test';
$this->Email->send('Hello message body!');

There seems to be no way to debug - expect of the return value of the send-Method which is basically false. Does somebody have an idea how to debug this? Ord even better - has a bulletproof solution for mails? Thank you!
