The 'results of your email commands' message in response to a message to a list's -join address can be wrong.
If a list's subscribe policy is Moderate, a message to the list's -join address produces a 'results of your email commands' response that says
- Results:
Confirmation email sent to Display Name <user@example.com>
Where Display Name <user@example.com>
is the user requesting subscription. This is not correct. It should say the request has been forwarded to a moderator for approval.
