POSTLOGD(8)                 System Manager's Manual                POSTLOGD(8)

NAME
       postlogd - Postfix internal log server
SYNOPSIS
       postlogd [generic Postfix daemon options]
DESCRIPTION
       This program logs events on behalf of Postfix programs when the maillog
       configuration parameter specifies a non-empty value.
BUGS
       Non-daemon Postfix programs don't know that  they  should  log  to  the
       internal  logging  service  before  they  have  processed  command-line
       options and main.cf parameters. These programs still log earlier events
       to the syslog service.
       If  Postfix  is down, the non-daemon programs postfix(1), postsuper(1),
       postmulti(1), and postlog(1), will log directly to $maillog_file. These
       programs expect to run with root privileges, for example during Postfix
       start-up, reload, or shutdown.
       Other non-daemon Postfix programs will never write directly  to  $mail-
       log_file (also, logging to stdout would interfere with the operation of
       some of these programs). These programs can log to postlogd(8) if  they
       are run by the super-user, or if their executable file has set-gid per-
       mission. Do not set this permission on programs other than  postdrop(1)
       and postqueue(1).
CONFIGURATION PARAMETERS
       Changes  to  main.cf  are  picked up automatically, as postlogd(8) pro-
       cesses run for only a limited amount of time. Use the command  "postfix
       reload" to speed up a change.
       The  text  below provides only a parameter summary. See postconf(5) for
       more details including examples.
       config_directory (see 'postconf -d' output)
              The default location of the Postfix main.cf and  master.cf  con-
              figuration files.
       maillog_file (empty)
              The  name  of an optional logfile that is written by the Postfix
              postlogd(8) service.
       process_id (read-only)
              The process ID of a Postfix command or daemon process.
       process_name (read-only)
              The process name of a Postfix command or daemon process.
       syslog_name (see 'postconf -d' output)
              A prefix that  is  prepended  to  the  process  name  in  syslog
              records, so that, for example, "smtpd" becomes "prefix/smtpd".
       service_name (read-only)
              The master.cf service name of a Postfix daemon process.
       postlogd_watchdog_timeout (10s)
              How  much  time  a  postlogd(8)  process  may  take to process a
              request before it is terminated by a built-in watchdog timer.
