Messages will be re-tried up to 30 days. See https://help.proofpoint.com/Proofpoint_Essentials/Email_Security/Administrator_Topics/110_logs/Deferred_message_redelivery_attempt_intervals for specific retry intervals
|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.|

In order to get a clear understanding of why an email was deferred or bounced, the easiest way is to locate the email in the Proofpoint Essentials log, Click on details under the Actions column, and then scroll down to Per-Recipient Classification & Delivery Status. This will include the server error from the attempted delivery to help diagnose why emails are being rejected when Proofpoint attempts to deliver them.
