E-Mail System

Getting email validation straightened out for successful email transmissions (DKIM, SPF and PTR, oh my!)

One of the things Drupal does is generate emails for a variety of reasons. For example new account registrations include a step to validate the account, by sending an email containing a validation link. On the large online community website I run, a long-running problem has been that the validation email does not always get delivered. This shows up as a user registration that never gets validated.
