Exchange 2016 error 530 validating sender

Relaying email is not one of those granted permissions. Exchange, by default will not all unauthenticated users to relay mail through your server.

Message traces show no record of the affected emails existing on our end.To understand and see the your mail server response , you will need to open telnet session to your mail server and use standard SMTP commands to see the mail server response and what is going on so you can remedy the problems.For the past several months, my organization has been experiencing a strange issue with incoming mail to Exchange Online/Office 365.I tried creating a new receive connector for "Internet (For example, to receive internet mail)" But it gives me error that port and ip bindings must be unique. Based on that assumption here is my answer: Your Exchange server is already configured to your requirements by default.Here is how: Exchange 2013 receives email through "Receive Connectors".

Meaning, email received on this connector by an anonymous client must be destined for a mailbox inside your Exchange organization or it will be rejected.

I was thinking about that the other night when I went to sleep.
