Hi Everyone, 

We are having an issue when configurating Odoo we are using our own mail servers Exchange 2019 - And when we do the test message we get the following error message 

Invalid Operation

Close

The server refused the test recipient (noreply@odoo.com) with error b'5.7.54 SMTP; Unable to relay recipient in non-accepted domain'

Is there anyway to change so we can send the test emails 

Thank you in advance
