title: Django : mail_admins() doesn't works
body: <p>I try to use mail_admins() instead of send_mail (it's works) but it doesn't works...</p>
  
  <p>My view :</p>
  
  <pre><code>...
  if request.method == "POST":
      form = contactForm(request.POST)
      if form.is_valid():
          sujet = form.cleaned_data['sujet']
          message= form.cleaned_data['message']
          try:
              mail_admins(subject=sujet, message=message)
  ...
  </code></pre>
  
  <p>My settings :</p>
  
  <pre><code>EMAIL_USE_TLS = True
  EMAIL_USE_SSL = True
  EMAIL_HOST = 'smtp.gmail.com'
  DEFAULT_FROM_EMAIL = "zor@gmail.com"
  SERVER_EMAIL = "zor@gmail.com"
  EMAIL_PORT = 587
  EMAIL_HOST_USER = "zor@gmail.com"
  EMAIL_HOST_PASSWORD = "mdp_of_zor@gmail.com"
  </code></pre>
  
  <p>Why I don't receive message in this adress (zor@gmail.com) ??</p>
