django-mailtestfield

Drop-in replacement for Django's forms.EmailField. Uses http://mailtest.in to validate email addresses against a number of factors. Caches results and fails silently should anything go wrong.

MailTest

http://mailtest.in is a free email domain validation API. Reject email addresses from invalid domains (i.e. the domain is unregistered or has no MX records). Optionally reject disposable email addresses and monetized bounce services.

Installation

You can install django-mailtestfield with pip by typing:

pip install django-mailtestfield

Or with easy_install by typing:

easy_install django-mailtestfield

Or manually by downloading a tarball and typing:

python setup.py install

Usage

Simply import the form field and use it:

from django import forms
from mailtest.fields import EmailMailTestField

class MyForm(forms.Form):
    email = EmailMailTestField()

Testing

See the dummy subdomains on the MailTest website. E.g. to test for a disposable email address response, use the email address "hello@disposable.mailtest.in".
