Outsider send email to our company email but it doesnt get deliver to exchange server.
I have check logs in D:\Program Files\Microsoft\Exchange Server\V15\TransportRoles\Logs\FrontEnd\ProtocolLog\SmtpReceive
it is showing Unable to relay recipient in non-accepted domain
Is there a receive / send connector i need to configure?
However, i try to send email from my personal hotmail to exchange, the email is received.
How can i resolve this? why is this happening?
