Description
Most of the time, you will receive a delivery-error message when a message has been sent to an invalid address or one that is not reachable. These error notification messages, if correctly formatted, contain a collection of data called DSN (delivery Status Notification) that contains information about the type of error (temporary or permanent).
The Bounce extension analyzes these messages to determine if they were sent from an email address stored in your database. The message will then be marked “bounced”, and you won’t hear from it again.
