NAME

6       error - Postfix error/retry mail delivery agent
7

SYNOPSIS

9       error [generic Postfix daemon options]
10

DESCRIPTION

12       The  Postfix  error(8)  delivery agent processes delivery requests from
13       the queue manager. Each  request  specifies  a  queue  file,  a  sender
14       address,  the reason for non-delivery (specified as the next-hop desti‐
15       nation), and recipient information.  The reason may be prefixed with an
16       RFC  3463-compatible  detail code; if none is specified a default 4.0.0
17       or 5.0.0 code is used instead.  This program expects to be run from the
18       master(8) process manager.
19
20       Depending  on the service name in master.cf, error or retry, the server
21       bounces or defers all recipients in  the  delivery  request  using  the
22       "next-hop"  information  as the reason for non-delivery. The retry ser‐
23       vice name is supported as of Postfix 2.4.
24
25       Delivery status reports are sent to the bounce(8), defer(8) or trace(8)
26       daemon as appropriate.
27

SECURITY

29       The  error(8) mailer is not security-sensitive. It does not talk to the
30       network, and can be run chrooted at fixed low privilege.
31

STANDARDS

33       RFC 3463 (Enhanced Status Codes)
34

DIAGNOSTICS

36       Problems and transactions are logged to syslogd(8).
37
38       Depending on the setting of the notify_classes parameter, the  postmas‐
39       ter is notified of bounces and of other trouble.
40

CONFIGURATION PARAMETERS

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