Silex + Swift Mailer not working

Question

I have a Silex application with Swift Mailer, but it looks like the configuration was not loaded from $app['swiftmailer.options'].

I registered the service in my boot file

$app->register(new SwiftmailerServiceProvider());

And in my configuration file

$app['swiftmailer.options'] = array(
    'host' => 'smtp.mandrillapp.com',
    'port' => '587',
    'username' => 'MY_USERNAME',
    'password' => 'MY_PASSWORD',
    'encryption' => null,
    'auth_mode' => null
);

And then I send my email address using

$message = \Swift_Message::newInstance()
    ->setSubject($this->app['forum_name'] . ' Account Verification')
    ->setFrom(array('[e-mail]'))
    ->setTo(array('[e-mail]'))
    ->setBody('My email content')
    ->setContentType("text/html");

$this->app['mailer']->send($message);

The send function returns 1, but the message was never sent. But when I try to manually create an instance Swift_SmtpTransport, an email will be sent.

$transport = \Swift_SmtpTransport::newInstance('smtp.mandrillapp.com', 587)
    ->setUsername('MY_USERNAME')
    ->setPassword('MY_PASSWORD');
...
$mailer = \Swift_Mailer::newInstance($transport);
$mailer->send($message);

So the problem is that it $app['swiftmailer.options']does not read and does not load. Did I miss something?

I follow the instructions here .

Answer 1

SwiftmailerServiceProvider TERMINATE ( ). Application->run(), . .

Silex,

if ($app['mailer.initialized']) {
    $app['swiftmailer.spooltransport']
        ->getSpool()
        ->flushQueue($app['swiftmailer.transport']);
}

SwiftmailerServiceProvider.

$app['swiftmailer.use_spool'] = false;

Answer 2

:

$app->register(new \Silex\Provider\SwiftmailerServiceProvider(), array(
   'swiftmailer.options' => array(
        'sender' => 'sender',
        'host' => 'host',
        'port' => 'port',
        'username' => 'username',
        'password' => 'password'
   )
));
