title: Laravel Mail not sending to Log
body: <p>I am having some troubles with Laravel 5.8 and sending the Mail into the logs for testing purposes.</p>
  
  <p>Regular log level INFO gets written to the daily log without any trouble.</p>
  
  <p>What am I missing in my current config?</p>
  
  <p><strong>.ENV file has :</strong></p>
  
  <pre><code>MAIL_DRIVER=log
  BROADCAST_DRIVER=log
  CACHE_DRIVER=file
  QUEUE_CONNECTION=sync
  LOG_CHANNEL=stack
  </code></pre>
  
  <p><strong>Mail.php</strong></p>
  
  <p>'driver' => env('MAIL_DRIVER', 'smtp'),
   'log_channel' => env('MAIL_LOG_CHANNEL'),</p>
  
  <p><strong>Logging.php</strong></p>
  
  <pre><code> 'default' =&gt; env('LOG_CHANNEL', 'stack'),
  'stack' =&gt; [
              'driver' =&gt; 'stack',
              'channels' =&gt; ['daily'],
          ],
  </code></pre>
