<b>NAME</b>
|
||
|
|
postmap - Postfix lookup table management
|
||
|
|
|
||
|
|
<b>SYNOPSIS</b>
|
||
|
|
<b>postmap</b> [<b>-Ninvw</b>] [<b>-c</b> <i>config_dir</i>] [<b>-q</b> <i>key</i>]
|
||
|
|
[<i>file_type</i>:]<i>file_name</i> ...
|
||
|
|
|
||
|
|
<b>DESCRIPTION</b>
|
||
|
|
The <b>postmap</b> command creates or queries one or more Postfix
|
||
|
|
lookup tables, or updates an existing one. The input and
|
||
|
|
output file formats are expected to be compatible with:
|
||
|
|
|
||
|
|
<b>makemap</b> <i>file_type</i> <i>file_name</i> < <i>file_name</i>
|
||
|
|
|
||
|
|
While the table update is in progress, signal delivery is
|
||
|
|
postponed, and an exclusive, advisory, lock is placed on
|
||
|
|
the entire table, in order to avoid surprises in spectator
|
||
|
|
programs.
|
||
|
|
|
||
|
|
The format of a lookup table input file is as follows:
|
||
|
|
|
||
|
|
<b>o</b> Blank lines are ignored. So are lines beginning
|
||
|
|
with `#'.
|
||
|
|
|
||
|
|
<b>o</b> A table entry has the form
|
||
|
|
|
||
|
|
<i>key</i> whitespace <i>value</i>
|
||
|
|
|
||
|
|
<b>o</b> A line that starts with whitespace continues the
|
||
|
|
preceding line.
|
||
|
|
|
||
|
|
The <i>key</i> and <i>value</i> are processed as is, except that sur-
|
||
|
|
rounding white space is stripped off. Unlike with Postfix
|
||
|
|
alias databases, quotes cannot be used to protect lookup
|
||
|
|
keys that contain special characters such as `#' or
|
||
|
|
whitespace. The <i>key</i> is mapped to lowercase to make mapping
|
||
|
|
lookups case insensitive.
|
||
|
|
|
||
|
|
Options:
|
||
|
|
|
||
|
|
<b>-N</b> Include the terminating null character that termi-
|
||
|
|
nates lookup keys and values. By default, Postfix
|
||
|
|
does whatever is the default for the host operating
|
||
|
|
system.
|
||
|
|
|
||
|
|
<b>-c</b> <i>config_dir</i>
|
||
|
|
Read the <b>main.cf</b> configuration file in the named
|
||
|
|
directory.
|
||
|
|
|
||
|
|
<b>-i</b> Incremental mode. Read entries from standard input
|
||
|
|
and do not truncate an existing database. By
|
||
|
|
default, <b>postmap</b> creates a new database from the
|
||
|
|
entries in <b>file</b><i>_</i><b>name</b>.

|
<b>-n</b> Don't include the terminating null character that
|
||
|
|
terminates lookup keys and values. By default,
|
||
|
|
Postfix does whatever is the default for the host
|
||

operating system.
|

|
|
|

|
|
<b>-q</b> <i>key</i> Search the specified maps for <i>key</i> and print the
|
||
|
|
first value found on the standard output stream.
|
||
|
|
The exit status is non-zero if the requested infor-
|
||
|
|
mation was not found.
|
||
|
|
|
||
|
|
<b>-v</b> Enable verbose logging for debugging purposes. Mul-
|
||
|
|
tiple <b>-v</b> options make the software increasingly
|
||
|
|
verbose.
|
||
|
|
|
||
|
|
<b>-w</b> Do not warn about duplicate entries; silently
|
||
|
|

Arguments:
|
||
|
|
|
||
|
|
<i>file_type</i>
|
||
|
|
The type of database to be produced.
|
||
|
|
|
||
|
|
<b>btree</b> The output file is a btree file, named
|
||
|
|
<i>file_name</i><b>.db</b>. This is available only on
|
||
|
|
systems with support for <b>db</b> databases.
|
||
|
|
|
||
|
|
<b>dbm</b> The output consists of two files, named
|
||
|
|
<i>file_name</i><b>.pag</b> and <i>file_name</i><b>.dir</b>. This is
|
||
|
|
available only on systems with support for
|
||
|
|
<b>dbm</b> databases.
|
||
|
|
|
||
|
|
<b>hash</b> The output file is a hashed file, named
|
||
|
|
<i>file_name</i><b>.db</b>. This is available only on
|
||
|
|
systems with support for <b>db</b> databases.
|
||
|
|
|
||
|
|
When no <i>file_type</i> is specified, the software uses
|
||
|
|
the database type specified via the <b>database</b><i>_</i><b>type</b>
|
||
|
|
configuration parameter.
|
||
|
|
|
||
|
|
<i>file_name</i>
|
||
|
|
The name of the lookup table source file when
|
||
|
|
rebuilding a database.
|
||
|
|
|
||
|
|
<b>DIAGNOSTICS</b>
|
||
|
|
Problems and transactions are logged to the standard error
|
||
|
|
stream. No output means no problems. Duplicate entries are
|
||
|
|
skipped and are flagged with a warning.
|
||
|
|
|
||
|
|
<b>ENVIRONMENT</b>
|
||
|
|
<b>MAIL</b><i>_</i><b>CONFIG</b>
|
||
