Answers.Text: I haven't confirmed but think this is still true: https://civicrm.stackexchange.com/a/16336/181. I.e. that if your rule of a given type is marked reserved then it doesn't matter what it's called or the settings, it uses an internal function. So you would need to make a NEW rule with email only that isn't the reserved one and mark it supervised. I think.

  <p>When adding a new Individual in backend, the Email only Dedupe rule doesn't work. When I enter the email address, no other data, of a known contact, it does not find the duplicate. If I enter the First Name, no other data, it finds duplicates. First and Last Names also work, but Email alone doesn't work. Using original rules. I want the de-duplication rule to work when only the Email is entered. What am I missing?</p>
