Hello there, 
 Thank you for contacting the Sophos Community. 
 Are you using Mail Flow? If so, the only time I have seen that error is when a customer just configured the Connectors and test right away; this happens because the connector hasn't fully been created. 
 If you have waited for more than 15 minutes, or you are not using Email Flow, I would recommend you to open a case with support to get this investigated. 
 As per your second comment, I am not sure what you meant. Where is not accepted? 
 Regards,
