NAME

       error - Postfix error mail delivery agent

SYNOPSIS

       error [generic Postfix daemon options]

DESCRIPTION

       The  Postfix  error(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 non-
       delivery, and recipient information.  This program expects  to  be  run
       from the master(8) process manager.

       The  error(8)  delivery  agent  bounces  all recipients in the delivery
       request using the "next-hop" domain or host information as  the  reason
       for  non-delivery,  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 bounce(8), defer(8) or trace(8)
       daemon as appropriate.

SECURITY

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

STANDARDS

       None.

DIAGNOSTICS

       Problems and transactions are logged to syslogd(8).

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

CONFIGURATION PARAMETERS

       Changes to main.cf 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.

       max_idle (100s)
              The maximum amount of time that an idle Postfix  daemon  process

       max_use (100)
