Answer 1

You can write your own clean functions for the form:

class RegistrationForm(ModelForm):
    username = forms.CharField(label=(u'User Name'))
    email = forms.EmailField(label = (u'Email Adress'))

    def clean_email(self):
        data = self.cleaned_data['email']
        if "@gmail.com" not in data:   # any check you need
            raise forms.ValidationError("Must be a gmail address")
        return data

    class Meta:
        model = UserProfile
        exclude = ('user',)

Answer 2

You can achieve the same via HTML5 input tag attribute (pattern). Say for example your domain is foo.com, then the code will be:

<input id="email" type="email" pattern="[a-z.]*[@]\bfoo.com" required>

Also you can change the error message by using the setCustomValidity of the DOM element.

document.getElementById('email').setCustomValidity("Please use an @foo.com email address.");
