Laravel Gmail 不工作，“用户名和密码不被接受.了解更多..."

When I try to send an e-mail through my website running Laravel 4, I get this exception:

{"error":{"type":"Swift_TransportException","message":"Expected response code 250 but got code "535", with message "535-5.7.8 Username and Password not accepted. Learn more at
535 5.7.8 http://support.google.com/mail/bin/answer.py?answer=14257 y70sm14744455qgd.3 - gsmtp
"","file":"/var/www/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php","line":386}}

这是我的邮件配置:

return array(
  'driver' => 'smtp',
  'host' => 'smtp.gmail.com',
  'port' => 465,
  'from' => array('address' => 'mymail@gmail.com', 'name' => 'myname'),
  'encryption' => 'ssl',
  'username' => 'mymail@gmail.com',
  'password' => 'lol',
  'sendmail' => '/usr/sbin/sendmail -bs',
  'pretend' => false,
);

我已经尝试了通过谷歌搜索这个问题找到的禁用链接，但它没有任何区别.
