django. - -z Does not check properly if the DATABASE_URL is defined or not. It evaluates to True if it is not set or set to '' - Remove SECURE_SSL_REDIRECT in the django settings because this deployment is meant to behind Nginx which decrypts SSL packets. - Force mailman to start even with a lock. This _may_ not be the best idea but for now if everything is followed according to this guide.
