title: Django email validator language
body: <p>I'm developing a Django website in Spanish and using the email field. If the string typed in the form is not an email, it show a built-in error message in English. How can I change it to Spanish?</p>
  
  <p>In my settings.py I have set the language to spanish:</p>
  
  <pre><code>LANGUAGE_CODE = 'es' 
  </code></pre>
  
  <p>I also tried adding the following code to views.py:</p>
  
  <pre><code>from django.utils.translation import activate
  
  activate('es')
  </code></pre>
