Postfix discard mail delivery agent
discard [generic Postfix daemon options]
The Postfix discard
(8) delivery agent processes
delivery requests from
the queue manager. Each request specifies a queue file, a sender
address, a domain or host name that is treated as the reason for
discarding the mail, and recipient information.
The reason may be prefixed with an RFC 3463-compatible detail code.
This program expects to be run from the master
The discard(8) delivery agent pretends to deliver all recipients
in the delivery request, logs the "next-hop" domain or host
information as the reason for discarding the mail, updates the
queue file and marks recipients as finished or informs the
queue manager that delivery should be tried again at a later time.
Delivery status reports are sent to the trace(8)
daemon as appropriate.

to the network, and can be run chrooted at fixed low privilege.
