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
