SPF_NONE The sender’s domain does not have an SPF record. The SPF record is a registry that is added automatically when we create a hosting account, it serves to legitimize a client. If that email was sent without SPF, it is very likely a spammer. It is a critical failure, the mail should not be sent like this, that’s why it has been scored 4 hit points.
