Use custom email server for Magento based ecommerce shops

You will need to change code on the file : app/code/core/Mage/Core/Model/Email/Template.php

Comment out the existing getMail() method.

And replace the method with the following code.

Remember: changing the core Magento code is not the greatest idea as upgrade of Magento will eventually become a big issue at a later time (if you keep doing this).

You can consider this as a quick test if you can make external mail server working with magento. However, ideally you need to take a better approach.

public function getMail()
    {
        if (is_null($this->_mail)) {

            /*Start of added code to specify config*/
            $my_smtp_host = Mage::getStoreConfig('system/smtp/host');
            $my_smtp_port = Mage::getStoreConfig('system/smtp/port'); 

            $config = array(
                    'ssl' => 'tls',
                    'port' => $my_smtp_port,
                    'auth' => 'login',
                    'username' => 'account@gmail.com',
                    'password' => 'secret'
            );

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

            Zend_Mail::setDefaultTransport($transport);
            /*End of added code to specify config*/

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