<b>DESCRIPTION</b>
By default, the <a href="postconf.1.html"><b>postconf</b>(1)</a> command displays the values of
<a href="postconf.5.html"><b>main.cf</b></a> configuration parameters, and warns about possible
mis-typed parameter names (Postfix 2.9 and later). It can
also change <a href="postconf.5.html"><b>main.cf</b></a> configuration parameter values, or
display other configuration information about the Postfix
mail system.
Options:
<b>-a</b> List the available SASL server plug-in types. The
SASL plug-in type is selected with the
<b><a href="postconf.5.html#smtpd_sasl_type">smtpd_sasl_type</a></b> configuration parameter by specify-
ing one of the names listed below.
<b>cyrus</b> This server plug-in is available when Post-
fix is built with Cyrus SASL support.
<b>dovecot</b>
This server plug-in uses the Dovecot authen-
tication server, and is available when Post-
fix is built with any form of SASL support.
This feature is available with Postfix 2.3 and
later.
<b>-A</b> List the available SASL client plug-in types. The
SASL plug-in type is selected with the
<b><a href="postconf.5.html#smtp_sasl_type">smtp_sasl_type</a></b> or <b><a href="postconf.5.html#lmtp_sasl_type">lmtp_sasl_type</a></b> configuration
parameters by specifying one of the names listed
below.
<b>cyrus</b> This client plug-in is available when Post-
fix is built with Cyrus SASL support.
This feature is available with Postfix 2.3 and
later.
<b>-b</b> [<i>template</i><b>_</b><i>file</i>]
Display the message text that appears at the begin-
ning of delivery status notification (DSN) mes-
sages, replacing $<b>name</b> expressions with actual val-
ues as described in <a href="bounce.5.html"><b>bounce</b>(5)</a>.
To override the built-in templates, specify a tem-
plate file name at the end of the <a href="postconf.1.html"><b>postconf</b>(1)</a> com-
mand line, or specify a file name in <a href="postconf.5.html"><b>main.cf</b></a> with
the <b><a href="postconf.5.html#bounce_template_file">bounce_template_file</a></b> parameter.
To force selection of the built-in templates, spec-
ify an empty template file name on the <a href="postconf.1.html"><b>postconf</b>(1)</a>
command line (in shell language: "").
This feature is available with Postfix 2.3 and
later.
<b>-c</b> <i>config</i><b>_</b><i>dir</i>
The <a href="postconf.5.html"><b>main.cf</b></a> configuration file is in the named
directory instead of the default configuration
directory.
<b>-C</b> <i>class,...</i>
When displaying <a href="postconf.5.html"><b>main.cf</b></a> parameters, select only
parameters from the specified class(es):
<b>builtin</b>
Parameters with built-in names.
<b>service</b>
Parameters with service-defined names (the
first field of a <a href="master.5.html"><b>master.cf</b></a> entry plus a
Postfix-defined suffix).
<b>user</b> Parameters with user-defined names.
<b>all</b> All the above classes.
The default is as if "<b>-C all</b>" is specified.
<b>-d</b> Print <a href="postconf.5.html"><b>main.cf</b></a> default parameter settings instead of
actual settings. Specify <b>-df</b> to fold long lines
for human readability (Postfix 2.9 and later).
<b>-e</b> Edit the <a href="postconf.5.html"><b>main.cf</b></a> configuration file, and update
parameter settings with the "<i>name</i>=<i>value</i>" pairs on
the <a href="postconf.1.html"><b>postconf</b>(1)</a> command line. The file is copied to
a temporary file then renamed into place. Specify
quotes to protect special characters and whitespace
on the <a href="postconf.1.html"><b>postconf</b>(1)</a> command line.
The <b>-e</b> is no longer needed with Postfix version 2.8
and later.
<b>-f</b> Fold long lines when printing <a href="postconf.5.html"><b>main.cf</b></a> or <a href="master.5.html"><b>master.cf</b></a>
configuration file entries, for human readability.
This feature is available with Postfix 2.9 and
later.
<b>-h</b> Show <a href="postconf.5.html"><b>main.cf</b></a> parameter values without the "<i>name</i> = "
label that normally precedes the value.
<b>-l</b> List the names of all supported mailbox locking
methods. Postfix supports the following methods:
<b>flock</b> A kernel-based advisory locking method for
local files only. This locking method is
available on systems with a BSD compatible
library.
<b>fcntl</b> A kernel-based advisory locking method for
local and remote files.
<b>dotlock</b>
An application-level locking method. An
application locks a file named <i>filename</i> by
creating a file named <i>filename</i><b>.lock</b>. The
application is expected to remove its own
lock file, as well as stale lock files that
were left behind after abnormal termination.
<b>-m</b> List the names of all supported lookup table types.
In Postfix configuration files, lookup tables are
specified as <i>type</i><b>:</b><i>name</i>, where <i>type</i> is one of the
types listed below. The table <i>name</i> syntax depends
on the lookup table type as described in the <a href="DATABASE_README.html">DATA</a>-
<a href="DATABASE_README.html">BASE_README</a> document.
<b>btree</b> A sorted, balanced tree structure. This is
available on systems with support for Berke-
ley DB databases.
<b>cdb</b> A read-optimized structure with no support
for incremental updates. This is available
on systems with support for CDB databases.
<b>cidr</b> A table that associates values with Class-
less Inter-Domain Routing (CIDR) patterns.
This is described in <a href="cidr_table.5.html"><b>cidr_table</b>(5)</a>.
<b>dbm</b> An indexed file type based on hashing. This
is available on systems with support for DBM
databases.
<b>environ</b>
The UNIX process environment array. The
lookup key is the variable name. Originally
implemented for testing, someone may find
this useful someday.
<b>fail</b> A table that reliably fails all requests.
The lookup table name is used for logging.
This table exists to simplify Postfix error
tests.
<b>hash</b> An indexed file type based on hashing. This
is available on systems with support for
Berkeley DB databases.
<b>internal</b>
A non-shared, in-memory hash table. Its con-
tent are lost when a process terminates.
<b>ldap</b> (read-only)
Perform lookups using the LDAP protocol.
This is described in <a href="ldap_table.5.html"><b>ldap_table</b>(5)</a>.
<b>memcache</b>
Perform lookups using the memcache protocol.
This is described in <a href="memcache_table.5.html"><b>memcache_table</b>(5)</a>.
<b>mysql</b> (read-only)
Perform lookups using the MYSQL protocol.
This is described in <a href="mysql_table.5.html"><b>mysql_table</b>(5)</a>.
<b>pcre</b> (read-only)
A lookup table based on Perl Compatible Reg-
ular Expressions. The file format is
described in <a href="pcre_table.5.html"><b>pcre_table</b>(5)</a>.
<b>pgsql</b> (read-only)
Perform lookups using the PostgreSQL proto-
col. This is described in <a href="pgsql_table.5.html"><b>pgsql_table</b>(5)</a>.
<b>proxy</b> A lookup table that is implemented via the
Postfix <a href="proxymap.8.html"><b>proxymap</b>(8)</a> service. The table name
syntax is <i>type</i><b>:</b><i>name</i>.
<b>regexp</b> (read-only)
A lookup table based on regular expressions.
The file format is described in <a href="regexp_table.5.html"><b>regexp_ta-</b></a>
<a href="regexp_table.5.html"><b>ble</b>(5)</a>.
<b>sdbm</b> An indexed file type based on hashing. This
is available on systems with support for
SDBM databases.
<b>sqlite</b> (read-only)
Perform lookups from SQLite database files.
This is described in <a href="sqlite_table.5.html"><b>sqlite_table</b>(5)</a>.
<b>static</b> (read-only)
A table that always returns its name as
lookup result. For example, <b><a href="DATABASE_README.html#types">static</a>:foobar</b>
always returns the string <b>foobar</b> as lookup
result.
<b>tcp</b> (read-only)
Perform lookups using a simple request-reply
protocol that is described in <a href="tcp_table.5.html"><b>tcp_table</b>(5)</a>.
<b>texthash</b> (read-only)
Produces similar results as hash: files,
except that you don't need to run the
<a href="postmap.1.html"><b>postmap</b>(1)</a> command before you can use the
file, and that it does not detect changes
after the file is read.
<b>unix</b> (read-only)
A limited way to query the UNIX authentica-
tion database. The following tables are
implemented:
<b>unix:passwd.byname</b>
The table is the UNIX password data-
base. The key is a login name. The
result is a password file entry in
<b>passwd</b>(5) format.
<b>unix:group.byname</b>
The table is the UNIX group database.
The key is a group name. The result
is a group file entry in <b>group</b>(5)
format.
Other table types may exist depending on how Post-
fix was built.
<b>-M</b> Show <a href="master.5.html"><b>master.cf</b></a> file contents instead of <a href="postconf.5.html"><b>main.cf</b></a>
file contents. Specify <b>-Mf</b> to fold long lines for
human readability.
If <i>service ...</i> is specified, only the matching ser-
vices will be output. For example, "<b>postconf -Mf</b>
<b>inet</b>" will output all services that listen on the
network.
Specify zero or more arguments, each with a <i>ser-</i>
<i>vice-type</i> name (<b>inet</b>, <b>unix</b>, <b>fifo</b>, or <b>pass</b>) or with
a <i>service-name.service-type</i> pair, where <i>service-</i>
<i>name</i> is the first field of a <a href="master.5.html">master.cf</a> entry.
This feature is available with Postfix 2.9 and
later.
<b>-n</b> Print <a href="postconf.5.html"><b>main.cf</b></a> parameter settings that are explic-
itly specified in <a href="postconf.5.html"><b>main.cf</b></a>. Specify <b>-nf</b> to fold
long lines for human readability (Postfix 2.9 and
later).
<b>-t</b> [<i>template</i><b>_</b><i>file</i>]
Display the templates for text that appears at the
beginning of delivery status notification (DSN)
messages, without expanding $<b>name</b> expressions.
To override the built-in templates, specify a tem-
plate file name at the end of the <a href="postconf.1.html"><b>postconf</b>(1)</a> com-
mand line, or specify a file name in <a href="postconf.5.html"><b>main.cf</b></a> with
the <b><a href="postconf.5.html#bounce_template_file">bounce_template_file</a></b> parameter.
To force selection of the built-in templates, spec-
ify an empty template file name on the <a href="postconf.1.html"><b>postconf</b>(1)</a>
command line (in shell language: "").
This feature is available with Postfix 2.3 and
later.
<b>-v</b> Enable verbose logging for debugging purposes. Mul-
tiple <b>-v</b> options make the software increasingly
verbose.
<b>-#</b> Edit the <a href="postconf.5.html"><b>main.cf</b></a> configuration file, and comment
out the parameters given on the <a href="postconf.1.html"><b>postconf</b>(1)</a> command
line, so that those parameters revert to their
default values. The file is copied to a temporary
file then renamed into place. Specify a list of
parameter names, not <i>name</i>=<i>value</i> pairs. There is no
<a href="postconf.1.html"><b>postconf</b>(1)</a> command to perform the reverse opera-
tion.
