title: Send email on GAE using Django module (django.core.mail)
body: <p>Before the migration of my app to GAE, I was using the following code to send emails and it worked pretty good:</p>
  
  <pre><code>from django.core.mail import send_mail
  
  subject = 'Hello!'
  msg = '\n \n Hello World!'
  sender = settings.DEFAULT_FROM_EMAIL
  to = ['xx@xx.com']
  
  send_mail(subject,msg,sender,to,fail_silently=False)
  </code></pre>
  
  <p>Now, after the migration to GAE (on Python 2.7) it doesn't work. It just throw the following error:</p>
  
  <pre><code>Exception Type: NotImplementedError
  Exception Location: C:\Program Files(x86)\Google\google_appengine\google\appengine\api\remote_socket\_remote_socket.py in gethostbyaddr, line 256
  </code></pre>
  
  <p>I have the settings.py file configured as follo</p>
  
  <pre><code>EMAIL_USE_TLS = True
  EMAIL_HOST = 'xxx.yyy.com'
  EMAIL_HOST_USER = 'my.account@yy.com'
  EMAIL_HOST_PASSWORD = 'zzzzzzzzz'
  EMAIL_PORT = 587
  </code></pre>
  
  <p>Does anyone send e-mails with Django module on GAE and know something about that error?</p>
