Unusual signals are the behavior or traits of an email that look suspicious to Cloud Email Gateway
                     Protection. A single unusual signal does not mean
                  a definite threat but can indicate possible risks. When detecting one unusual signal
                  in an email message, Cloud Email Gateway
                     Protection supports taking
                  action on the message. For details about unusual signals, see Unusual signals.
|  | NoteTrend Micro recommends that you use the "Do not intercept messages" and "Insert
                                 stamp in body" actions for unusual signal detection. A default stamp "Unusual
                                 signal detection" is available for use. |
