title: mail address validation in python/django
body: <p>We are developing our website in django framework and with python. currently we are looking for an api/a tool to validate the physical addres the user enters. It doesn't need to be vey sophisticated. We just need to avoid spam registrations. For this step, we need to verify if country, state, city, and zipcode are belong to each other. For instance, Berkeley as a city with Zipcode 94704 is not in NY state, etc.
  Any thoughts?</p>
