A line that + starts with whitespace continues a logical line. + + The <i>key</i> and <i>value</i> are processed as is, except that surrounding white + space is stripped off. Whitespace in lookup keys is supported in Post- + fix 3.2 and later, by surrounding the key with double quote characters + `"'. Within the double quotes, double quote `"' and backslash `\' char- + acters can be included by quoting them with a preceding backslash. + + When the <b>-F</b> option is given, the <i>value</i> must specify one or more file- + names separated by comma and/or whitespace; <a href="postmap.1.html"><b>postmap</b>(1)</a> will concatenate + the file content (with a newline character inserted between files) and + will store the base64-encoded result instead of the <i>value</i>. + + When the <i>key</i> specifies email address information, the localpart should + be enclosed with double quotes if required by <a href="https://tools.ietf.org/html/rfc5322">RFC 5322</a>. For example, an + address localpart that contains ";", or a localpart that starts or ends + with ".". + + By default the lookup key is mapped to lowercase to make the lookups + case insensitive; as of Postfix 2.3 this case folding happens only with + tables whose lookup keys are fixed-case strings such as <a href="DATABASE_README.html#types">btree</a>:, <a href="DATABASE_README.html#types">dbm</a>: or + <a href="DATABASE_README.html#types">hash</a>:. With earlier versions, the lookup key is folded even with tables + where a lookup field can match both upper and lower case text, such as + <a href="regexp_table.5.html">regexp</a>: and <a href="pcre_table.5.html">pcre</a>:. This resulted in loss of information with $<i>number</i> + substitutions. + +<b>COMMAND-LINE ARGUMENTS</b> + <b>-b</b> Enable message body query mode. When reading lookup keys from + standard input with "<b>-q -</b>", process the input as if it is an + email message in <a href="https://tools.ietf.org/html/rfc5322">RFC 5322</a> format. Each line of body content + becomes one lookup key. + + By default, the <b>-b</b> option starts generating lookup keys at the + first non-header line, and stops when the end of the message is + reached. To simulate <a href="header_checks.5.html"><b>body_checks</b>(5)</a> processing, enable MIME + parsing with <b>-m</b>. With this, the <b>-b</b> option generates no + body-style lookup keys for attachment MIME headers and for + attached message/* headers. + + NOTE: with "<a href="postconf.5.html#smtputf8_enable">smtputf8_enable</a> = yes", the <b>-b</b> option disables UTF-8 + syntax checks on query keys and lookup results. Specify the <b>-U</b> + option to force UTF-8 syntax checks anyway. + + This feature is available in Postfix version 2.6 and later. + + <b>-c</b> <i>config</i><b>_</b><i>dir</i> + Read the <a href="postconf.5.html"><b>main.cf</b></a> configuration file in the named directory + instead of the default configuration directory. + + <b>-d</b> <i>key</i> Search the specified maps for <i>key</i> and remove one entry per map. + The exit status is zero when the requested information was + found. + + If a key value of <b>-</b> is specified, the program reads key values + from the standard input stream. The exit status is zero when at + least one of the requested keys was found. + + <b>-f</b> Do not fold the lookup key to lower case while creating or + querying a table. + + With Postfix version 2.3 and later, this option has no effect + for regular expression tables. There, case folding is controlled + by appending a flag to a pattern. + + <b>-F</b> When querying a map, or listing a map, base64-decode each value. + When creating a map from source file, process each value as a + list of filenames, concatenate the content of those files, and + store the base64-encoded result instead of the value (see INPUT + FILE FORMAT for details). + + This feature is available in Postfix version 3.4 and later. + + <b>-h</b> Enable message header query mode. When reading lookup keys from + standard input with "<b>-q -</b>", process the input as if it is an + email message in <a href="https://tools.ietf.org/html/rfc5322">RFC 5322</a> format. Each logical header line + becomes one lookup key. A multi-line header becomes one lookup + key with one or more embedded newline characters. + + By default, the <b>-h</b> option generates lookup keys until the first + non-header line is reached. To simulate <a href="header_checks.5.html"><b>header_checks</b>(5)</a> pro- + cessing, enable MIME parsing with <b>-m</b>. With this, the <b>-h</b> option + also generates header-style lookup keys for attachment MIME + headers and for attached message/* headers. + + NOTE: with "<a href="postconf.5.html#smtputf8_enable">smtputf8_enable</a> = yes", the <b>-b</b> option option dis- + ables UTF-8 syntax checks on query keys and lookup results. + Specify the <b>-U</b> option to force UTF-8 syntax checks anyway. + + This feature is available in Postfix version 2.6 and later. + + <b>-i</b> Incremental mode.

By default, <a href="postmap.1.html"><b>postmap</b>(1)</a> creates a + new database from the entries in <b>file_name</b>. + + <b>-m</b> Enable MIME parsing with "<b>-b</b>" and "<b>-h</b>". + + This feature is available in Postfix version 2.6 and later. + + <b>-N</b> Include the terminating null character that terminates lookup + keys and values.

By default, <a href="postmap.1.html"><b>postmap</b>(1)</a> does whatever is + the default for the host operating system. + + <b>-o</b> Do not release root privileges when processing a non-root input + file. By default, <a href="postmap.1.html"><b>postmap</b>(1)</a> drops root privileges and runs as + the source file owner instead. + + <b>-p</b> Do not inherit the file access permissions from the input file + when creating a new file. Instead, create a new file with + default access permissions (mode 0644). + + <b>-q</b> <i>key</i> Search the specified maps for <i>key</i> and write the first value + found to the standard output stream. The exit status is zero + when the requested information was found. + + Note: this performs a single query with the key as specified, + and does not make iterative queries with substrings of the key + as described for <a href="access.5.html">access(5)</a>, <a href="canonical.5.html">canonical(5)</a>, <a href="transport.5.html">transport(5)</a>, <a href="virtual.5.html">vir-</a> + <a href="virtual.5.html">tual(5)</a> and other Postfix table-driven features. + + If a key value of <b>-</b> is specified, the program reads key values + from the standard input stream and writes one line of <i>key value</i> + output for each key that was found. The exit status is zero when + at least one of the requested keys was found. + + <b>-r</b> When updating a table, do not complain about attempts to update + existing entries, and make those updates anyway. + + <b>-s</b> Retrieve all database elements, and write one line of <i>key value</i> + output for each element. The elements are printed in database + order, which is not necessarily the same as the original input + order. + + This feature is available in Postfix version 2.2 and later, and + is not available for all database types. + + <b>-u</b> Disable UTF-8 support. UTF-8 support is enabled by default when + "<a href="postconf.5.html#smtputf8_enable">smtputf8_enable</a> = yes". It requires that keys and values are + valid UTF-8 strings. + + <b>-U</b> With "<a href="postconf.5.html#smtputf8_enable">smtputf8_enable</a> = yes", force UTF-8 syntax checks with the + <b>-b</b> and <b>-h</b> options. + + <b>-v</b> Enable verbose logging for debugging purposes.

To find out what types are supported, use the + "<b>postconf -m</b>" command. + + The <a href="postmap.1.html"><b>postmap</b>(1)</a> command can query any supported file type, but it + can create only the following file types: + + <b>btree</b> The output file is a btree file, named <i>file</i><b>_</b><i>name</i><b>.db</b>. + This is available on systems with support for <b>db</b> data- + bases. + + <b>cdb</b> The output consists of one file, named <i>file</i><b>_</b><i>name</i><b>.cdb</b>. + This is available on systems with support for <b>cdb</b> data- + bases. + + <b>dbm</b> The output consists of two files, named <i>file</i><b>_</b><i>name</i><b>.pag</b> and + <i>file</i><b>_</b><i>name</i><b>.dir</b>.
