Send confirmation email when changing the email in Django

I'm currently using django-registration, and it is working well (with some tricks). When the user registers, he has to check his/her mail and click on the activation link. That's fine, but...

What if the user changes the email? I would like to send him/her an email in order to confirm that he is the owner of the email address...

Is there an application, snippet, or something that would save me the time of writing it by myself?

I've faced the same issue recently. And I didn't like the idea of having another app/plugin for just that.

You can achieve that by, listening to User model's singles(pre_save, post_save) and using RegistrationProfile:

signals.py: 

from django.contrib.sites.models import Site, RequestSite
from django.contrib.auth.models import User
from django.db.models.signals import post_save, pre_save
from django.dispatch import receiver
from registration.models import RegistrationProfile


# Check if email change
@receiver(pre_save,sender=User)
def pre_check_email(sender, instance, **kw):
    if instance.id:
        _old_email = instance._old_email = sender.objects.get(id=instance.id).email
        if _old_email != instance.email:
            instance.is_active = False

@receiver(post_save,sender=User)
def post_check_email(sender, instance, created, **kw):
    if not created:
        _old_email = getattr(instance, '_old_email', None)
        if instance.email != _old_email:
            # remove registration profile
            try:
                old_profile = RegistrationProfile.objects.get(user=instance)
                old_profile.delete()
            except:
                pass

            # create registration profile
            new_profile = RegistrationProfile.objects.create_profile(instance)

            # send activation email
            if Site._meta.installed:
                site = Site.objects.get_current()
            else:
                site = RequestSite(request)
            new_profile.send_activation_email(site)

So whenever a User's email is changed, the user will be deactivated and an activation email will be send to the user.
