.SH DESCRIPTION
.ad
.fi
The \fBpostconf\fR(1) command prints the actual value of
\fIparameter\fR (all known parameters by default) one
parameter per line, changes its value, or prints other
information about the Postfix mail system.

Options:
.IP "\fB-c \fIconfig_dir\fR"
The \fBmain.cf\fR configuration file is in the named directory
instead of the default configuration directory.
.IP \fB-d\fR
Print default parameter settings instead of actual settings.
.IP \fB-e\fR
Edit the \fBmain.cf\fR 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 protect shell metacharacters and whitespace.
.IP \fB-h\fR
Show parameter values only, not the ``name = '' label
that normally precedes the value.
.IP \fB-l\fR
List the names of all supported mailbox locking methods.
Postfix supports the following methods:
.RS
.IP \fBflock\fR
A kernel-based advisory locking method for local files only.
This locking method is available on systems with a BSD
compatible library.
.IP \fBfcntl\fR
A kernel-based advisory locking method for local and remote files.
.IP \fBdotlock\fR
An application-level locking method. An application locks a file
named \fIfilename\fR by creating a file named \fIfilename\fB.lock\fR.
The application is expected to remove its own lock file, as well as
stale lock files that were left behind after abnormal termination.
.RE
.IP \fB-m\fR
List the names of all supported lookup table types. In Postfix
configuration files,
lookup tables are specified as \fItype\fB:\fIname\fR, where
\fItype\fR is one of the types listed below. The table \fIname\fR
syntax depends on the lookup table type as described in the
DATABASE_README document.
.RS
.IP \fBbtree\fR
A sorted, balanced tree structure.
This is available on systems with support for Berkeley DB
databases.
.IP \fBcdb\fR
A read-optimized structure with no support for incremental updates.
This is available on systems with support for CDB databases.
.IP \fBcidr\fR
A table that associates values with Classless Inter-Domain Routing
(CIDR) patterns. This is described in \fBcidr_table\fR(5).
.IP \fBdbm\fR
An indexed file type based on hashing.
This is available on systems with support for DBM databases.
.IP \fBenviron\fR
The UNIX process environment array. The lookup key is the variable
name. Originally implemented for testing, someone may find this
useful someday.
.IP \fBhash\fR
An indexed file type based on hashing.
This is available on systems with support for Berkeley DB
databases.
.IP "\fBldap\fR (read-only)"
Perform lookups using the LDAP protocol. This is described
in \fBldap_table\fR(5).
.IP "\fBmysql\fR (read-only)"
Perform lookups using the MYSQL protocol. This is described
in \fBmysql_table\fR(5).
.IP "\fBpcre\fR (read-only)"
A lookup table based on Perl Compatible Regular Expressions. The
file format is described in \fBpcre_table\fR(5).
.IP "\fBpgsql\fR (read-only)"
Perform lookups using the PostgreSQL protocol. This is described
in \fBpgsql_table\fR(5).
.IP "\fBproxy\fR (read-only)"
A lookup table that is implemented via the Postfix
\fBproxymap\fR(8) service. The table name syntax is
\fItype\fB:\fIname\fR.
.IP "\fBregexp\fR (read-only)"
A lookup table based on regular expressions. The file format is
described in \fBregexp_table\fR(5).
.IP \fBsdbm\fR
An indexed file type based on hashing.
This is available on systems with support for SDBM databases.
.IP "\fBstatic\fR (read-only)"
A table that always returns its name as lookup result. For example,
\fBstatic:foobar\fR always returns the string \fBfoobar\fR as lookup
result.
.IP "\fBtcp\fR (read-only)"
Perform lookups using a simple request-reply protocol that is
described in \fBtcp_table\fR(5).
This feature is not included with Postfix 2.2.
.IP "\fBunix\fR (read-only)"
A limited way to query the UNIX authentication database. The
following tables are implemented:
.RS
. IP \fBunix:passwd.byname\fR
The table is the UNIX password database. The key is a login name.
The result is a password file entry in \fBpasswd\fR(5) format.
.IP \fBunix:group.byname\fR
The table is the UNIX group database. The key is a group name.
The result is a group file entry in \fBgroup\fR(5) format.

.RE
.sp
Other table types may exist depending on how Postfix was built.
.IP \fB-n\fR
Print parameter settings that are not left at their built-in
default value, because they are explicitly specified in main.cf.
.IP \fB-v\fR
Enable verbose logging for debugging purposes. Multiple \fB-v\fR
options make the software increasingly verbose.
