title: fwrite() ssl broken pipe in swiftmailer while sending email
body: <p>I am using Laravel 5.2. I am using Mail queue for sending email. Following is email queue syntax.</p>
  
  <pre><code>$mailArr = array();
  $mailArr['subject'] = 'testing mail';
  $mail_body = 'testing mail';
  $mailArr['description'] =  $mail_body;
  Mail::to($email)-&gt;queue(new CustomMail($mailArr));
  </code></pre>
  
  <ul>
  <li>If I use "send" instead of "queue" then successfully receiving email.</li>
  <li>Queue emails are going in Job table and attempting 3 times and then it is going in failed_jobs table.</li>
  <li>In failed_jobs table, I am getting error ErrorException: fwrite(): SSL: Broken pipe in vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php:231</li>
  <li>I am processing queue with dispatcher and supervisor.</li>
  <li>If I manually hit php artisan queue:work even then email is going but automatically with schedule:run written in cron job, is not working.</li>
  </ul>
  
  <p>So any suggestions please what could be the reason?</p>
