title: Django Email Backend Setting Not Working
body: <p>I have a unit test with a test-specific settings file, which includes:</p>
  
  <pre><code>EMAIL_BACKEND = 'django.core.mail.backends.filebased.EmailBackend'
  EMAIL_FILE_PATH = '/my/file/path'
  </code></pre>
  
  <p>This wasn't working, so I dropped into the debugger to check the settings in the middle of running my test:</p>
  
  <pre><code>ipdb&gt; from django.conf import settings
  ipdb&gt; settings.EMAIL_BACKEND
  'django.core.mail.backends.locmem.EmailBackend'
  ipdb&gt; settings.EMAIL_FILE_PATH
  '/my/file/path'
  </code></pre>
  
  <p>The file path setting worked, but the backend setting didn't!</p>
  
  <p>Does anyone know why? </p>
  
  <p>What else could I check/configure?</p>
  
  <p>Is this something for a bug report?</p>
  
  <p>Django 1.11</p>
