[TYPO3-mvc] MailMessage class in TYPO3 7.2 How to use it?

[Dmitry]

Hi all,
In my extension in TYPO3 6.2.x I sent mail through the function.

protected function sendMail($senderEmail, $recipientEmail, $subject, $message) {
    $this->view->assign('settings', $this->settings);   
    $mail = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Core\\Mail\\MailMessage');
    $mail->setFrom(array($this->settings['fromEmail']));
    $mail->setTo(array($this->settings['toEmail']));
    $mail->setSubject($this->settings['subject']);
    $mail->setBody(htmlspecialchars_decode($message), 'text/html');
    if($this->settings['debugMail'] == 1) {
        $this->debug($message);
    } else {
        $mail->send();
    }
}

It worked good. But in TYPO3 7.2 it's not working. How to use it?
