class OverrideUserMailRequiredValidator in Administer Users by Role 8.3

Checks if the user's email address is provided if required.

The user mail field is NOT required if account originally had no mail set and the user performing the edit has permission to set empty user mail. This allows users without email address to be edited and deleted.
