## Postfix master process configuration file. Each logical line # describes how a Postfix daemon program should be run. ## A logical line starts with non-whitespace, non-comment text.# Empty lines and whitespace-only lines are ignored, as are comment # lines whose first non-whitespace character is a `#'. # A line that starts with whitespace continues a logical line.## The fields that make up each line are described below. A "-" field# value requests that a default value be used for that field.## Service: any name that is valid for the specified transport type# (the next field). With INET transports, a service is specified as# host:port. The host part (and colon) may be omitted. Either host# or port may be given in symbolic form or in numeric form. Examples# for the SMTP server: localhost:smtp receives mail via the loopback# interface only; 10025 receives mail on port 10025.## Transport type: "inet" for Internet sockets, "unix" for UNIX-domain# sockets, "fifo" for named pipes.## Private: whether or not access is restricted to the mail system.# Default is private service. Internet (inet) sockets can't be private.## Unprivileged: whether the service runs with root privileges or as# the owner of the Postfix system (the owner name is controlled by the# mail_owner configuration variable in the main.cf file). Only the# pipe, virtual and local delivery daemons require privileges.## Chroot: whether or not the service runs chrooted to the mail queue# directory (pathname is controlled by the queue_directory configuration# variable in the main.cf file). Presently, all Postfix daemons can run# chrooted, except for the pipe, virtual and local delivery daemons.# The proxymap server can run chrooted, but doing so defeats most of# the purpose of having that service in the first place.# The files in the examples/chroot-setup subdirectory describe how# to set up a Postfix chroot environment for your type of machine.## Wakeup time: automatically wake up the named service after the# specified number of seconds. A ? at the end of the wakeup time# field requests that wake up events be sent only to services that# are actually being used. Specify 0 for no wakeup. Presently, only# the pickup, queue manager and flush daemons need a wakeup timer.## Max procs: the maximum number of processes that may execute this# service simultaneously. Default is to use a globally configurable# limit (the default_process_limit configuration parameter in main.cf).# Specify 0 for no process count limit.## Command + args: the command to be executed. The command name is# relative to the Postfix program directory (pathname is controlled by# the daemon_directory configuration variable). Adding one or more# -v options turns on verbose logging for that service; adding a -D# option enables symbolic debugging (see the debugger_command variable# in the main.cf configuration file). See individual command man pages# for specific command-line options, if any.## General main.cf options can be overridden for specific services.# To override one or more main.cf options, specify them as arguments# below, preceding each option by "-o". There must be no whitespace# in the option itself (separate multiple values for an option by# commas).## In order to use the "uucp" message tranport below, set up entries# in the transport table.## In order to use the "cyrus" message transport below, configure it# in main.cf as the mailbox_transport.## SPECIFY ONLY PROGRAMS THAT ARE WRITTEN TO RUN AS POSTFIX DAEMONS.# ALL DAEMONS SPECIFIED HERE MUST SPEAK A POSTFIX-INTERNAL PROTOCOL.## DO NOT SHARE THE POSTFIX QUEUE BETWEEN MULTIPLE POSTFIX INSTANCES.## ==========================================================================# service type private unpriv chroot wakeup maxproc command + args# (yes) (yes) (yes) (never) (100)# ==========================================================================# JRD smtp inet n - n - 300 smtpdsmtp inet n - n - 150 smtpd#submission inet n - n - - smtpd# -o smtpd_etrn_restrictions=reject#628 inet n - n - - qmqpdpickup fifo n - n 60 1 pickupcleanup unix n - n - 0 cleanupqmgr fifo n - n 300 1 qmgr#qmgr fifo n - n 300 1 oqmgrrewrite unix - - n - - trivial-rewritebounce unix - - n - 0 bouncedefer unix - - n - 0 bouncetrace unix - - n - 0 bounceverify unix - - n - 1 verifyflush unix n - n 1000? 0 flushproxymap unix - - n - - proxymap# JRD smtp unix - - n - 150 smtpsmtp unix - - n - 75 smtpslow unix - - n - 1 smtprelay unix - - n - - smtp# -o smtp_helo_timeout=5 -o smtp_connect_timeout=5showq unix n - n - - showqerror unix - - n - - error# JRD local unix - n n - 60 locallocal unix - n n - 30 localvirtual unix - n n - - virtuallmtp unix - - n - - lmtpanvil unix - - n - 1 anvil## Interfaces to non-Postfix software.
