What is the best way to send Django 500 error email on Google App Engine?

I'm using the latest tools provided by the latest Google App Engine (GAE) environment, i.e. Django 1.3 via

libraries:
- name: django
  version: "1.3"

as instructed by the GAE docs here.

Still, although I found a lot of links discussing how to send the blessed HTTP500 email using the powerful GAE-Django combo, all of them are outdated because they are either simply too old or use "additional" tools like AppEngineHelper or django-nonrel.

Back to my problem: I set up my settings.py to follow the Django docs instructions here, and since on GAE opening sockets is restricted I end up with this traceback:

ERROR    2012-03-21 23:11:15,855 base.py:209] Internal Server Error: /contact/
Traceback (most recent call last):
  File "/home/josvic/dev-tools/google_appengine/lib/django_1_3/django/core/handlers/base.py", line 111, in get_response
    response = callback(request, *callback_args, **callback_kwargs)
  File "/home/josvic/dev/qdsa/gae/apputil/decorators.py", line 14, in wrapper
    output = func(request, *args, **kw)
  File "/home/josvic/dev/qdsa/gae/qdcom/views/contact.py", line 26, in __call__
    return self.f(request, *args, **kwargs)
  File "/home/josvic/dev/qdsa/gae/qdcom/views/contact.py", line 59, in contact_page
    msg.send()
  File "/home/josvic/dev-tools/google_appengine/lib/django_1_3/django/core/mail/message.py", line 251, in send
    return self.get_connection(fail_silently).send_messages([self])
  File "/home/josvic/dev-tools/google_appengine/lib/django_1_3/django/core/mail/backends/smtp.py", line 79, in send_messages
    new_conn_created = self.open()
  File "/home/josvic/dev-tools/google_appengine/lib/django_1_3/django/core/mail/backends/smtp.py", line 42, in open
    local_hostname=DNS_NAME.get_fqdn())
  File "/home/josvic/dev-tools/google_appengine/lib/django_1_3/django/core/mail/utils.py", line 16, in get_fqdn
    self._fqdn = socket.getfqdn()
AttributeError: 'module' object has no attribute 'getfqdn'

So that is the problem. Do we have a standard way of circumventing this?

The only thing I can think of to bypass this problem is to resort to a custom 500error handler that uses GAE's standard mail API.

Two options I can think of are:

  1. Custom logging handler that uses GAE standard mail API, not too different from a 500 error handler, but you don't have to rewrite the view: https://docs.djangoproject.com/en/dev/topics/logging/

  2. Replace the email backend. I'm not 100% certain this works, but I suspect it will. There's already one in the Django-nonrel project (which incidentally, is still maintained) https://github.com/django-nonrel/djangoappengine look in mail.py
