Not utterly pointless. They allow users to get information that would
otherwise require an administrator to search the logs. Why do they want
that information? Because it allows them to determine whether their
organisation has discharged its responsibility in sending a communication.

This legal case was won because it was possible to demonstrate that an
email (serving notice of arbitration, in accordance with a contract) had
been delivered to the recipient's mail system.
