Name

double_bounce_sender

Possible values:

email address

Default:

double-bounce

A double bounce is produced when the original sender of a message cannot be notified that the message was not delivered. The double_bounce_sender parameter specifies the sender address Postfix uses for mail that should be discarded if it cannot be delivered. The specified address should not be used for anything else since all messages addressed to it are silently discarded.

Example:

double_bounce_sender = double-bounce
