send mails via sendgrid

Question

I'm trying to send mails via sendgrid, here my code :

// Setup Swift mailer parameters
        $transport = Swift_SmtpTransport::newInstance('smtp.sendgrid.net', 25);
        $transport->setUsername($username);
        $transport->setPassword($password);
        $swift = Swift_Mailer::newInstance($transport);

        // Create a message (subject)
        $message = new Swift_Message($subject);

        // attach the body of the email
        $message->setFrom($from);
        $message->setBody($html, 'text/html');
        $message->setTo($to);
        $message->addPart($text, 'text/plain');

        // send message
        if ($recipients = $swift->send($message, $failures))
        {              
          // This will let us know how many users received this message
          echo 'Message sent out to '.$recipients.' users';exit;
        }

I got this error : Swift_TransportException

Expected response code 250 but got code "", with message ""

...\swiftMailer\lib\classes\Swift\Transport\AbstractSmtpTransport.php(422)

please help me !

Please contact the vendor of the library for support questions. — hakre

Try to send the message in one line to see if that works or returns another error. If it returns an error, it's probably a server or authentication issue.

$result = $swift->send($message);

If that works, you could try the code below and if it works tweak it so it shows your recipients instead of failures.

if (!$swift->send($message, $failures))
{
  echo "Failures:";
  print_r($failures);
}

Other than that, check if all variables are not empty.

For more examples see: http://swiftmailer.org/docs/sending.html#quick-reference-for-sending-a-message

UPDATE

Sendmail code:

//Create the Transport
$transport = Swift_MailTransport::newInstance();

//Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);

//Create a message
$message = Swift_Message::newInstance('Subject')
  ->setFrom(array('[email protected]' => 'John Doe'))
  ->setTo(array('[email protected]', '[email protected]' => 'A name'))
  ->setBody('Here is the message itself')
  ;

//Send the message
$numSent = $mailer->send($message);

printf("Sent %d messages\n", $numSent);
