POSTCONF(1)                                                        POSTCONF(1)




NAME

       postconf - Postfix configuration utility


SYNOPSIS

       postconf [-dhmlnv] [-c config_dir] [parameter ...]

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


DESCRIPTION

       The  postconf  command  prints the actual value of parameter (all known
       parameters by default) one parameter per line, changes  its  value,  or
       prints other information about the Postfix mail system.

       Options:

       -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.

       -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 only  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.  Postfix
              lookup  tables  are specified as type:name, where type is one of
              the types listed below. The table name  syntax  depends  on  the
              lookup table type.

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

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

              ldap (read-only)
                     Perform  lookups  using  the  LDAP  protocol.   This   is
                     described in an LDAP_README file.

              mysql (read-only)
                     Perform   lookups  using  the  MYSQL  protocol.  This  is
                     described in a MYSQL_README file.

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

              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.

              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 non-default parameter settings only.

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