title: Laravel 5.1 Mail::send .env configuration doesn't work
body: <p>I have a queued job that is supposed to send emails. I keep getting an error:</p>
  
  <blockquote>
    <p>Swift_TransportException(code: 530): Expected response code 250 but
    got code \"530\", with message \"530 5.7.1 Authentication
    required\r\n\" at
    /my/project/path/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/AbstractSmtpTransport.php:383</p>
  </blockquote>
  
  <p>I tried using <code>mail</code>, <code>sendmail</code> and <code>smtp</code> drivers. However if I set config values directly via <code>mail.php</code> in <code>config</code> dir it seems to work fine.</p>
  
  <p>Once I get back to <code>.env</code> configuration it's the same problem again.</p>
  
  <p>I tried outputting <code>.env</code> and <code>config</code> values in my templates - they all seem fine.</p>
  
  <p>Any ideas what might be causing this?</p>
