I am running magento 1.9.1 website on AWS EC2 Ubuntu machine. Customer registration emails are going out but transnational emails are not going.

I configure SMTP by AWS SES service with SMTP Pro extension. I got below error on email sending

cron_schedule table is also empty

Described config is functional, for viewing changes in scripts is
needed to turn off Magento compiler an clean /includes/folder.

There is changed email function supporting Google Gmail or Google
Apps:

1 copy file "app/code/core/Mage/Core/Model/Email/Template.php" to
"app/code/local/Mage/Core/Model/Email/Template.php"

2 In file app/code/local/Mage/Core/Model/Email/Template.php change
function:

public function getMail()

{

    if (is_null($this->_mail)) {

    $my_smtp_host = Mage::getStoreConfig('system/smtp/host');

    $my_smtp_port = Mage::getStoreConfig('system/smtp/port');

    $config = array(

              'port' => $my_smtp_port,

              'auth' => 'login',

              'ssl' => 'tls',

              'username' => 'youremail@gmail.com',

              'password' => 'Abc'

              );

     $transport = new Zend_Mail_Transport_Smtp($my_smtp_host,$config);

     Zend_Mail::setDefaultTransport($transport);         











        $this->_mail = new Zend_Mail('utf-8');

    }

    return $this->_mail;

}

Disable compiler, rename folder /includes/ in magento root and clear
cache

Another solution try this:-

> Try to disabled TLS Support or add valid certificate into smtp mail
program.
