Set a different SMTP for Newsletter in Magento - magento

Question

i was wondering if it's possible to set two different SMTP server on Magento:
one for the Newsletter and one for the Magento System emails.
I saw around that is possible to set SMTP in template.php but that will affect all the emails. Is then possible two different ones?
Thank you all !!
Ps:
I tried to modify the file /app/code/core/Mage/Newsletter/Model/Template.php
as suggested on post :
Magento - How enable SMTP server authentication and secure transport?
and used the code in this way:
public function getMail()
{
if (is_null($this->_mail)) {
/*Start of added code to specify config*/
$my_smtp_host = 'smtp.mysmtp.com'; // Take it from Magento backoffice or you can specify it here
$my_smtp_port = '587'; // Take it from Magento backoffice or you can specify it here
$config = array(
'port' => $my_smtp_port, //optional - default 25
'auth' => 'login',
'username' => 'mylogin#email.it',
'password' => 'mypassword'
);
$transport = new Zend_Mail_Transport_Smtp($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;
}
Unfortunatly is taking the system smtp instead of using this one.
I also commented the two lines:
ini_set('SMTP', Mage::getStoreConfig('system/smtp/host'));
ini_set('smtp_port', Mage::getStoreConfig('system/smtp/port'));
Any idea why is still using the system one?

Answer 1

Mail transport is set up and executed from these two functions
Mage_Core_Model_Email_Template -> send() in /app/code/core/Mage/Core/Model/Email/Template.php for Transactional Emails
Mage_Newsletter_Model_Template -> send() in /app/code/core/Mage/Newsletter/Model/Template.php for Newsletters
Here's the working module code I created to direct transactional emails through our email service provider. It is not a paste-in for the newsletter send() function!
Note that you will need to hard code the extra config items for your purposes as this code sample is missing the setup to add the fields to system config, but it should give you an idea of how the send() function needs to be changed for the Newsletter module. I personally don't use the Newsletter module as we have a service provider for promotional emails to keep from poisoning our domain by false flagging as a spam source.
public function send($email, $name = null, array $variables = array())
{
if (!$this->isValidForSend()) {
Mage::logException(new Exception('This letter cannot be sent.')); // translation is intentionally omitted
return false;
}
/* Set up mail transport to Email Hosting Provider SMTP Server via SSL/TLS */
$config = array(
'ssl' => Mage::getStoreConfig('system/smtp/ssl'), // option of none, ssl or tls
'port' => Mage::getStoreConfig('system/smtp/port'), // TLS 587 - SSL 465 - default 25
'auth' => Mage::getStoreConfig('system/smtp/auth'), // Auth type none, login, plain, CRAM-MD5
'username' => Mage::getStoreConfig('system/smtp/username'),
'password' => Mage::getStoreConfig('system/smtp/password')
);
/* Set up transport package to host */
$transport = new Zend_Mail_Transport_Smtp(Mage::getStoreConfig('system/smtp/host'), $config);
/* End transport setup */
$emails = array_values((array)$email);
$names = is_array($name) ? $name : (array)$name;
$names = array_values($names);
foreach ($emails as $key => $email) {
if (!isset($names[$key])) {
$names[$key] = substr($email, 0, strpos($email, '#'));
}
}
$variables['email'] = reset($emails);
$variables['name'] = reset($names);
// ini_set('SMTP', Mage::getStoreConfig('system/smtp/host'));
// ini_set('smtp_port', Mage::getStoreConfig('system/smtp/port'));
$mail = $this->getMail();
$setReturnPath = Mage::getStoreConfig(self::XML_PATH_SENDING_SET_RETURN_PATH);
switch ($setReturnPath) {
case 1:
$returnPathEmail = $this->getSenderEmail();
break;
case 2:
$returnPathEmail = Mage::getStoreConfig(self::XML_PATH_SENDING_RETURN_PATH_EMAIL);
break;
default:
$returnPathEmail = null;
break;
}
if ($returnPathEmail !== null) {
$mailTransport = new Zend_Mail_Transport_Sendmail("-f".$returnPathEmail);
Zend_Mail::setDefaultTransport($mailTransport);
}
foreach ($emails as $key => $email) {
$mail->addTo($email, '=?utf-8?B?' . base64_encode($names[$key]) . '?=');
}
$this->setUseAbsoluteLinks(true);
$text = $this->getProcessedTemplate($variables, true);
if($this->isPlain()) {
$mail->setBodyText($text);
} else {
$mail->setBodyHTML($text);
}
$mail->setSubject('=?utf-8?B?' . base64_encode($this->getProcessedTemplateSubject($variables)) . '?=');
$mail->setFrom($this->getSenderEmail(), $this->getSenderName());
try {
/* Send Transport, empty and log success */
$mail->send($transport); //transport object
$this->_mail = null;
Mage::log('Mailed to: ' . $this->getSenderEmail() . ' ' . $this->getSenderName() . ' ' .$this->getProcessedTemplateSubject($variables), null, 'email.log');
/* End */
}
catch (Exception $e) {
/* Or empty and log failure */
$this->_mail = null;
Mage::log('Failure: ' . $e, null, 'email.log');
Mage::logException($e);
return false;
/* End */
}
return true;
