SwiftMailer + Gmail - Cannot send email

Question

I can't connect with Gmail SMTP server.

Look:

$transport = Swift_SmtpTransport::newInstance()
            ->setHost('smtp.gmail.com')
            ->setPort(465)
            ->setEncryption('ssl')
            ->setUsername('email@gmail.com')
            ->setPassword('mypasss');

    $mailer = Swift_Mailer::newInstance($transport);

    $message = Swift_Message::newInstance('Contato via Site')
            ->setFrom(array($email => $de))
            ->setTo(array($destinatario => 'Agência Linka'))
            ->setBody($corpo_mensagem, 'text/html')
            ->setCharset('UTF-8');

    $mailer->send($message);

And then I get this:

Fatal error: Uncaught exception 'Swift_TransportException' with message 'Connection could not be established with host smtp.gmail.com [ #0]' in ...

Anyone has experienced this?

You can send mail by using tls instead of ssl certificate like below:

    $transport =  Swift_SmtpTransport::newInstance('smtp.gmail.com', 587,'tls')
                            ->setUsername('email@gmail.com')
                            ->setPassword('mypasss');

    $mailer = Swift_Mailer::newInstance($transport);

    $message = Swift_Message::newInstance('Contato via Site')
            ->setFrom(array($email => $de))
            ->setTo(array($destinatario => 'Agência Linka'))
            ->setBody($corpo_mensagem, 'text/html')
            ->setCharset('UTF-8');

    $mailer->send($message);
