    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,

    To know if you are using Mailflow or Gateway (two different modes), 
    Go to Central > Email Security > Settings.
    If the affected domain is in "Domain Settings/Status" page, then its a gateway mode.
    If the affected domain is in "M365 Mailflow Domain Settings/Status" page, then its a mailflow mode.

    The two example entries you presented on your original post seem to be unrelated. One seems to be an inbound issue, the other one seems to be an outbound issue. 

    We would recommend creating a support case for each in order for them to be investigated further.
