SwiftMailer + Gmail - 无法发送电子邮件

I can't connect with Gmail SMTP server.

看:

$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);

然后我得到了这个:

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

有人经历过吗?
