I'm trying to sends mails in PHP. The code I used for sending a mail in CakePHP is given below. I get the message 'Simple Email Sent' in my web page but the mail is not delivered to my inbox. Am I missing something?

The values in the to, subject and link fields are set with the values entered in the user interface.

    $this->set('to',$this->params['form']['to']);
    $this->set('subject',$this->params['form']['subject']);
    $this->set('link',$this->params['form']['link']);
    $this->Email->to      = to;
    $this->Email->subject = subject;
    $this->Email->from    = '[email protected]';
    $this->Email->delivery= 'mail';
    $this->Email->sendAs='text';
    $this->Email->template = 'simple_message';
    //$this->Email->send(link);
    if ( $this->Email->send(link) ) {

        $this->Session->setFlash('Simple email sent');
    } else {
        $this->Session->setFlash('Simple email not sent');
    }
