Exchange 2016 Unable to relay recipient in non-accepted domain

Hi expert,

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?
Thanks.

I am not clear
The outsider has to use their own mail server and not use your mail server to send mail.
