[support] Hosting services shuts off mail from user nobody

I am managing several Drupal sites, and the hosting service has shut off email from 'nobody' as a security risk. This breaks registration, password resets, notify, contact, and any other feature that sends email. There are a variety of confusing and possibly conflicting recommendations on the Drupal site about this problem. Most involve multi-step patches to each site, which becomes very difficult if you are managing multiple sites. Is the an "approved" way to deal with this problem?
