POSTCONF(1)							   POSTCONF(1)

NAME
       postconf - Postfix configuration utility

SYNOPSIS
       postconf [-dhnv] [-c config_dir] [parameter ...]

       postconf [-aAmlv] [-c config_dir]

       postconf [-ev] [-c config_dir] [parameter=value ...]

       postconf [-#v] [-c config_dir] [parameter ...]

       postconf [-btv] [-c config_dir] [template_file]

DESCRIPTION
       The  postconf(1)	 command  displays  the actual values of configuration
       parameters, changes configuration parameter values, or  displays	 other
       configuration information about the Postfix mail system.

       Options:

       -a     List  the available SASL server plug-in types.  The SASL plug-in
	      type is selected with the smtpd_sasl_type configuration  parame‐
	      ter by specifying one of the names listed below.

	      cyrus  This  server  plug-in  is available when Postfix is built
		     with Cyrus SASL support.

	      dovecot
		     This  server  plug-in  uses  the  Dovecot	authentication
		     server,  and  is available when Postfix is built with any
		     form of SASL support.

	      This feature is available with Postfix 2.3 and later.

       -A     List the available SASL client plug-in types.  The SASL  plug-in
	      type  is selected with the smtp_sasl_type or lmtp_sasl_type con‐
	      figuration parameters by specifying  one	of  the	 names	listed
	      below.

	      cyrus  This  client  plug-in  is available when Postfix is built
		     with Cyrus SASL support.

	      This feature is available with Postfix 2.3 and later.

       -b [template_file]
	      Display the message text that appears at the beginning of deliv‐
	      ery  status  notification (DSN) messages, with $name expressions
	      replaced by actual values.  To  override	the  built-in  message
	      text, specify a template file at the end of the command line, or
	      specify a template file in main.cf with the bounce_template_file
	      parameter.  To force selection of the built-in message text tem‐
	      plates, specify an empty template file name (in shell  language:
	      "").

	      This feature is available with Postfix 2.3 and later.

       -c config_dir
	      The main.cf configuration file is in the named directory instead
	      of the default configuration directory.

       -d     Print default parameter settings instead of actual settings.

       -e     Edit the main.cf configuration file. The file  is	 copied	 to  a
	      temporary	 file  then  renamed into place. Parameters and values
	      are specified on the command line. Use quotes in order  to  pro‐
	      tect shell metacharacters and whitespace.

	      With Postfix version 2.8 and later, the -e is no longer needed.

       -h     Show  parameter  values  only, not the "name = " label that nor‐
	      mally precedes the value.

       -l     List the names of all supported mailbox locking methods.	 Post‐
	      fix supports the following methods:

	      flock  A	kernel-based  advisory	locking method for local files
		     only.  This locking method is available on systems with a
		     BSD compatible library.

	      fcntl  A	kernel-based  advisory	locking	 method	 for local and
		     remote files.

	      dotlock
		     An application-level locking method. An application locks
		     a	file  named  filename  by  creating a file named file‐
		     name.lock.	 The application is expected to remove its own
		     lock  file,  as  well  as stale lock files that were left
		     behind after abnormal termination.

       -m     List the names of all supported lookup table types.  In  Postfix
	      configuration  files,  lookup tables are specified as type:name,
	      where type is one of the types listed below. The table name syn‐
	      tax  depends  on the lookup table type as described in the DATA‐
	      BASE_README document.

	      btree  A sorted, balanced tree structure.	 This is available  on
		     systems with support for Berkeley DB databases.

	      cdb    A	read-optimized structure with no support for incremen‐
		     tal updates.  This is available on systems	 with  support
		     for CDB databases.

	      cidr   A	table  that  associates	 values	 with Classless Inter-
		     Domain Routing (CIDR)  patterns.  This  is	 described  in
		     cidr_table(5).

	      dbm    An indexed file type based on hashing.  This is available
		     on systems with support for DBM databases.

	      environ
		     The UNIX process environment array. The lookup key is the
		     variable  name. Originally implemented for testing, some‐
		     one may find this useful someday.

	      hash   An indexed file type based on hashing.  This is available
		     on systems with support for Berkeley DB databases.

	      internal
		     A	non-shared, in-memory hash table. Its content are lost
		     when a process terminates.

	      ldap (read-only)
		     Perform  lookups  using  the  LDAP	 protocol.   This   is
		     described in ldap_table(5).

	      mysql (read-only)
		     Perform   lookups	using  the  MYSQL  protocol.  This  is
		     described in mysql_table(5).

	      pcre (read-only)
		     A lookup table based on Perl Compatible  Regular  Expres‐
		     sions. The file format is described in pcre_table(5).

	      pgsql (read-only)
		     Perform  lookups  using  the PostgreSQL protocol. This is
		     described in pgsql_table(5).

	      proxy (read-only)
		     A lookup table that is implemented via the Postfix	 prox‐
		     ymap(8) service. The table name syntax is type:name.

	      regexp (read-only)
		     A	lookup	table  based  on regular expressions. The file
		     format is described in regexp_table(5).

	      sdbm   An indexed file type based on hashing.  This is available
		     on systems with support for SDBM databases.

	      sqlite (read-only)
		     Perform  lookups  from  SQLite  database  files.  This is
		     described in sqlite_table(5).

	      static (read-only)
		     A table that always returns its name  as  lookup  result.
		     For example, static:foobar always returns the string foo‐
		     bar as lookup result.

	      tcp (read-only)
		     Perform lookups using  a  simple  request-reply  protocol
		     that is described in tcp_table(5).

	      texthash (read-only)
		     Produces  similar results as hash: files, except that you
		     don't need to run the postmap(1) command before  you  can
		     use  the  file, and that it does not detect changes after
		     the file is read.

	      unix (read-only)
		     A limited way to query the UNIX authentication  database.
		     The following tables are implemented:

		     unix:passwd.byname
			    The	 table	is the UNIX password database. The key
			    is a login name.  The result is  a	password  file
			    entry in passwd(5) format.

		     unix:group.byname
			    The table is the UNIX group database. The key is a
			    group name.	 The result is a group file  entry  in
			    group(5) format.

	      Other table types may exist depending on how Postfix was built.

       -n     Print  parameter	settings  that	are not left at their built-in
	      default value, because they are explicitly specified in main.cf.

       -t [template_file]
	      Display the templates for	 delivery  status  notification	 (DSN)
	      messages. To override the built-in templates, specify a template
	      file at the end of the command line, or specify a template  file
	      in  main.cf  with	 the bounce_template_file parameter.  To force
	      selection of the built-in templates, specify an  empty  template
	      file name (in shell language: "").

	      This feature is available with Postfix 2.3 and later.

       -v     Enable  verbose  logging	for  debugging	purposes.  Multiple -v
	      options make the software increasingly verbose.

       -#     Edit the main.cf configuration file. The file  is	 copied	 to  a
	      temporary file then renamed into place. The parameters specified
	      on the command line are commented-out, so that  they  revert  to
	      their  default  values.  Specify	a list of parameter names, not
	      name=value pairs.	 There is no postconf command to  perform  the
	      reverse operation.

	      This feature is available with Postfix 2.6 and later.
