Bounces and Deferrals Troubleshooting:

Delivered: Messages that are sent through Proofpoint Essentials platform and are delivered.

Quarantined: Message that are quarantined by one of the filters on the platform.

  • These messages can be released from Quarantine

Blocked: Message that are blocked because of a virus or executable file. 

  • Messages that are blocked are not allowed to be released.

Deferred: Message could not be delivered to the client’s/recipients server.

  • Messages will be re-tried up to 30 days. These emails will be automatically retried once every 5min, 15min, 30min and 1 hour after that for the next 30 days.
  • These errors are temporary and normally result in 400 error codes.

Bounced: Messages did not get delivered to the Recipient/customers server.

  • Messages get sent a Non-Delivery Report (NDR).
  • These are what we call a “hard bounce” normally 500 error codes.
  • These messages will need to be resent. 

Queued: This is a placeholder for our back-end logs to update the Front-end UI logs. This normally doesn’t indicate whether the message was delivered or not. If you want to know the true status please contact support.
