Ben (bu basit bir script özetliyor) ZendMail bir e-posta göndermek için çalışıyorum

<?php
require_once 'Zend/Mail.php';

$mail = new Zend_Mail();
$mail->setBodyText('My Nice Test Text');
$mail->setBodyHtml('My Nice Test Text');
$mail->setFrom('test@example.com', 'Mr Example');
$mail->addTo('contact@mypage.com', 'Mr Test');
$mail->setSubject('TestSubject');
$mail->send();
?>

Ancak ben bu yığın iz olsun:

Fatal error: Uncaught exception 'Zend_Mail_Transport_Exception' with message 'Unable to send mail. ' in /usr/share/php/libzend-framework-php/Zend/Mail/Transport/Sendmail.php:137 Stack trace: #0 /usr/share/php/libzend-framework-php/Zend/Mail/Transport/Abstract.php(348): Zend_Mail_Transport_Sendmail->_sendMail() #1 /usr/share/php/libzend-framework-php/Zend/Mail.php(1178): Zend_Mail_Transport_Abstract->send(Object(Zend_Mail)) #2 /var/www/hexreaction/mail/index2.php(11): Zend_Mail->send() #3 {main} thrown in /usr/share/php/libzend-framework-php/Zend/Mail/Transport/Sendmail.php on line 137

EDIT:

Bir sorun hala benim e-posta göndermek için SMTP kullanmaya çalışıyorum değilim ve ben daha az korkunç bir sorunu yaşıyorum ama.

<?php
require_once 'Zend/Mail.php';
$config = array('auth' => 'login',
                'username' => 'contact@mypage.com',
                'password' => 'secretpass');

$transport = new Zend_Mail_Transport_Smtp('smtp.gmail.com', $config);

$mail = new Zend_Mail();
$mail->setBodyText('This is the text of the mail.');
$mail->setFrom('contact@mypage.com', 'Some Sender');
$mail->addTo('contact@mypage.com', 'Some Recipient');
$mail->setSubject('TestSubject');
$mail->send($transport);
?>

Bu atımı bu hata, ben gerçekten alamadım neden:

Fatal error: Class 'Zend_Mail_Transport_Smtp' not found in /var/www/hexreaction/mail/index3.php on line 7

EDIT 2:

Bu benim son çalışma kodu

require_once('Zend/Mail/Transport/Smtp.php');
require_once 'Zend/Mail.php';
$config = array('auth' => 'login',
                'username' => 'somemail@mysite.com',
                'password' => 'somepass',
                'ssl' => 'tls');

$transport = new Zend_Mail_Transport_Smtp('smtp.gmail.com', $config);

$mail = new Zend_Mail();
$mail->setBodyText('This is the text of the mail.');
$mail->setFrom('somemail@mysite.com', 'Some Sender');
$mail->addTo('somemail@mysite.com', 'Some Recipient');
$mail->setSubject('TestSubject');
$mail->send($transport);
