    Hello @Hassan Oumar,

    Thank you for your question.

    To set up myhostname value properly it is required to set the fully qualified domain name (FQDN) that will be used in a sender address.

    As I can see from MXToolBox report myhostname is currently set as
    This value is the correct one as it meets the fully qualified domain name (FQDN) requirement.

    If you set myhostname value as, it would be correct as well.
