unauthenticated senders, notification

[netjess]

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.

Sorry, I think you are out of luck there. Exchange sends a generic message to unauthenticated users.

Exchange 2010 mail moderation is actually cool!!
