[1.7] Swift Mailer doesnt send message and no logs

[Kaysof]

I have problem to send test mail from localhost prestashop enviroment. Code completly doesnt show any information. I try to find out in Mail.php class and just know that this code:

/* Send mail */
$message->setFrom(array($from => $fromName));
$send = $swift->send($message);

make $send = 0. How can i verify what is the problem.
