title: Laravel 5.0 configuration file mail.php not loaded
body: <p>I have a problem with the configuration in Laravel 5.0</p>
  
  <p>I configured an environment <code>local</code> from an <code>.env</code> file. The machine is a homestead machine and i removed the <code>APP_ENV</code> from the <code>Homestead.yaml</code> just to be sure.</p>
  
  <p>Environment is set to local and i confirmed by prompting <code>$app-&gt;environment()</code></p>
  
  <p>I added a few configuration files to the local config directory (local/filesystems.php, local/mail.php, local/services.php). The interesting thing is the filesystems.php gets loaded but the mail one not. If i dump the <code>getConfigurationFiles()</code> from <code>Illuminate\Foundation\Bootstrap\LoadConfiguration</code> i get</p>
  
  <pre><code>array:11 [▼
    "app" =&gt; "/home/vagrant/Code/molkerei/config/app.php"
    "auth" =&gt; "/home/vagrant/Code/molkerei/config/auth.php"
    "cache" =&gt; "/home/vagrant/Code/molkerei/config/cache.php"
    "compile" =&gt; "/home/vagrant/Code/molkerei/config/compile.php"
    "database" =&gt; "/home/vagrant/Code/molkerei/config/database.php"
    "filesystems" =&gt; "/home/vagrant/Code/molkerei/config/local/filesystems.php"
    "mail" =&gt; "/home/vagrant/Code/molkerei/config/mail.php"
    "services" =&gt; "/home/vagrant/Code/molkerei/config/services.php"
    "queue" =&gt; "/home/vagrant/Code/molkerei/config/queue.php"
    "session" =&gt; "/home/vagrant/Code/molkerei/config/session.php"
    "view" =&gt; "/home/vagrant/Code/molkerei/config/view.php"
  ]
  </code></pre>
  
  <p>I already tried to clean the cache with <code>php artisan cache:clear</code> but there is not even a cache file (it is set to filesystem)</p>
  
  <p>Any idea why the configuration is not loaded properly?</p>
