✅

Here is how to do it (the right way).

Create a subclass of registration.forms.RegistrationForm:

class EmailDomainFilterRegistrationForm(RegistrationForm):

    def clean_email(self):
        submitted_data = self.cleaned_data['email']

        if not ALLOWED_DOMAINS: # If we allow any domain
            return submitted_data

        domain = submitted_data.split('@')[1]
        logger.debug(domain)
        if domain not in ALLOWED_DOMAINS:
            raise forms.ValidationError(
                u'You must register using an email address with a valid '
                'domain ({}). You can change your email address later on.'
                .format(', '.join(self.allowed_domains))
            )
        return submitted_data

Re-use django-registration‘s urls.py from whichever django-registration backend you’re using and change the registration_register url with

url(r'^register/$',
    RegistrationView.as_view(form_class=EmailDomainFilterRegistrationForm),
    name='registration_register'),

RegistrationView above depends on which of django-registration‘s backends you’re using. Don’t import it from the top level views.py. Import it from the applicable backend using ONE of the following statements:

from registration.backends.hmac.views import RegistrationView
from registration.backends.model_activation.views import RegistrationView
from registration.backends.simple.views import RegistrationView
