Hello, I created a mail cow server using steps in your documentation.
When I setup a connector in our O365 subscription and when we added mail rules, it is giving an error
The sender’s message was routed to an email server outside Office 365 that returned an error that it can’t relay the message. It’s likely that the server isn’t set up correctly to receive and relay messages sent from megooglem.com or from support.
Could you let me know how we can solve this problem or is there any additional configuration that we have to do on mail cow server side.
I am attaching a screenshot for your reference.
