Integrate Mailazy with Symfony

Symfony uses SwiftMailer to send email, read more about sending emails from Symfony. To get started you need to modify parameters.yml and add the following:

mailer:
class: sfMailer
param:
logging: %SF_LOGGING_ENABLED%
charset: %SF_CHARSET%
delivery_strategy: realtime
transport:
class: Swift_SmtpTransport
param:
host: smtp.mailazy.com
port: 587
encryption: ~
username: mailazy_apikey
api_key: mailazy_secret

After that you should be able to send emails. The following shows an example:

$message  = Swift_Message::newInstance()
->setFrom('[email protected]')
->setTo('[email protected]')
->setSubject('Subject')
->setBody('Body');
$this->getMailer()->send($message);

Another Option

If you want more flexibility, you can use partials to define the content of the emails. Add the a class such as lib/myEmail.class.php.

class myEmail
{
  /**
  * Library to facilitate email messages being sent out, sendMail deprecated in symfony 1.2
  * @param string $partial - Array with html and text partials ie array('text'=>'textPartial', 'html'=>'htmlPartial')
  * @param array $parameters - Array we will pass into the partials
  * @param string $mailFrom - Email source
  * @param string $mailTo - Email destination
  * @param string $subject - The subject of the email message
  * @param array $sgHeaders - What we will be placing in the SMTPAPI header. Must be null or a non-empty array
  * @param array $attachments - Email contains the attachments
  */
  public  static  function sendEmail($partials, $parameters, $mailFrom, $mailTo, $subject, $sgHeaders  = null, $attachments  = null)
  {
  // verify we have username/api_key to send out emails - IMPORTANT
  if (!sfconfig::has('mailazy_apikey') or  !sfconfig::has('mailazy_secret')) {
    throw  new sfException('SMTP mailazy_apikey/mailazy_secret is required to send email out');
  }

  $text  = null;
  $html  = null;
  if (is_array($partials)) {
    // load libraries
    sfContext::getInstance()->getConfiguration()->loadHelpers('Partial');
    if (isset($partials['text'])) {
      $text  = get_partial($partials['text'], $parameters);
    }
    if (isset($partials['html'])) {
      $html  = get_partial($partials['html'], $parameters);
    }
  }
  if ($text  === null &&  $html  === null) {
    throw  new sfException('A text and/or HTML partial must be given');
  }
  try {
  /*
  * Load connection for mailer
  */

    $connection  = Swift_SmtpTransport::newInstance('smtp.mailazy.com', 587, 'tls')->setUsername(sfconfig::get('mailazy_apikey'))->setPassword(sfconfig::get('mailazy_secret'));
    // setup connection/content
    $mailer  = Swift_Mailer::newInstance($connection);
    $message  = Swift_Message::newInstance()->setSubject($subject)->setTo($mailTo);
    if ($text  &&  $html) {
      $message->setBody($html, 'text/html');
      $message->addPart($text, 'text/plain');
    } else  if ($text) {
      $message->setBody($text, 'text/plain');
    } else {
      $message->setBody($html, 'text/html');
    }
    // if contains SMTPAPI header add it
    if (null !==  $sgHeaders) {
      $message->getHeaders()->addTextHeader('X-SMTPAPI', json_encode($sgHeaders));
    }

    // update the from address line to include an actual name
    if (is_array($mailFrom) and count($mailFrom) ==  2) {
      $mailFrom  =  array(
        $mailFrom['email'] =>  $mailFrom['name']
      );
    }

    // add attachments to email
    if ($attachments  !== null and is_array($attachments)) {
      foreach ($attachments  as  $attachment) {
        $attach  = Swift_Attachment::fromPath($attachment['file'], $attachment['mime'])->setFilename($attachment['filename']);
        $message->attach($attach);
      }
    }

    // Send
    $message->setFrom($mailFrom);
    $mailer->send($message);
  }
  catch (Exception $e) {
    throw  new sfException('Error sending email out - ' .  $e->getMessage());
  }
  }
}

Then configure your credentials on apps/frontend/app.yml

prod:
username: mailazy_apikey
password: mailazy_secret

Now can put your partials in a module such as apps/frontend/modules/mail. For example, to send a registration email in both text and HTML, we would have the following structure:

apps/
frontend/
modules/
mail/
_registrationHTML.php
_registrationTEXT.php

Add this to apps/frontend/modules/mail/\_registrationTEXT.php

Dear < ?php echo  $name  ?>,
Thank you for registering. Please go to http://domain.com to finish your registration.

Add this to apps/frontend/modules/mail/_registrationHTML.php

Dear < ?php echo  $name; ?>,

Thank you for registering. Please go to here to finish your registration.

And send the message as follow:

myEmail::sendEmail(array('text'=>'mail/registrationTEXT', 'html'=>'mail/registrationHTML'), array('name'=>'Recipient Name'), '[email protected]', '[email protected]', 'Registration Information');
