       error - Postfix error/retry mail delivery agent


       error [generic Postfix daemon options]


       The  Postfix  error(8)  delivery agent processes delivery requests from the queue manager.
       Each request specifies a queue  file,  a  sender  address,  the  reason  for  non-delivery
       (specified  as  the  next-hop  destination), and recipient information.  The reason may be
       prefixed with an RFC 3463-compatible detail code; if none is specified a default 4.0.0  or
       5.0.0  code  is  used  instead.  This program expects to be run from the master(8) process

       Depending on the service name in, error or retry, the server bounces  or  defers
       all  recipients in the delivery request using the "next-hop" information as the reason for
       non-delivery. The retry service name is supported as of Postfix 2.4.

       Delivery status reports are  sent  to  the  bounce(8),  defer(8)  or  trace(8)  daemon  as


       The error(8) mailer is not security-sensitive. It does not talk to the network, and can be
       run chrooted at fixed low privilege.


       RFC 3463 (Enhanced Status Codes)


       Problems and transactions are logged to syslogd(8) or postlogd(8).

       Depending on the setting of the notify_classes parameter, the postmaster  is  notified  of
       bounces and of other trouble.


       Changes  to  are  picked  up  automatically  as error(8) processes run for only a
       limited amount of time. Use the command "postfix reload" to speed up a change.
