Infinitely Getting: Delivery Status Notification (Failure)

[kalungia]

Hello,
When I send an email and it fails i get these Delivery Status Notification (Failure) or Undelivery that will not stop showing up in the communication, they don't stop being created, at a time i through it may be our mail server but i disconnect the email account and after some time we couldn't get them in our mail box, does anyone know how to stop this in frappe communication if email account fails or delivery failed no need to infinitely create the Delivery Status Notification (Failure) or Undelivery in the communication doctype.
