Greetings,
I am being asked to set some accounts to receive from authenticated only. That is easy. I have tested my mail server and it blocks the message but I can not find a way to have a response go back to the un-authenticated sender to notify them that their message was not received.
Is there a way to set such a message?
Thank you.
