The input and output file for- + mats are expected to be compatible with Sendmail version 8, and are + expected to be suitable for use as NIS alias maps. + + If the result files do not exist they will be created with the same + group and other read permissions as their source file. + + While a database update is in progress, signal delivery is postponed, + and an exclusive, advisory, lock is placed on the entire database, in + order to avoid surprises in spectator processes. + + The format of Postfix alias input files is described in <a href="aliases.5.html"><b>aliases</b>(5)</a>. + + 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. + + Options: + + <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>-i</b> Incremental mode. Read entries from standard input and do not + truncate an existing database. By default, <a href="postalias.1.html"><b>postalias</b>(1)</a> creates + a new database from the entries in <i>file</i><b>_</b><i>name</i>. + + <b>-N</b> Include the terminating null character that terminates lookup + keys and values. By default, <a href="postalias.1.html"><b>postalias</b>(1)</a> does whatever is the + default for the host operating system. + + <b>-n</b> Don't include the terminating null character that terminates + lookup keys and values. By default, <a href="postalias.1.html"><b>postalias</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="postalias.1.html"><b>postalias</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 in the <a href="aliases.5.html">aliases(5)</a> manual page. + + 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>-v</b> Enable verbose logging for debugging purposes. Multiple <b>-v</b> + options make the software increasingly verbose. + + <b>-w</b> When updating a table, do not complain about attempts to update + existing entries, and ignore those attempts. + + Arguments: + + <i>file</i><b>_</b><i>type</i> + The database type. To find out what types are supported, use the + "<b>postconf -m</b>" command. + + The <a href="postalias.1.html"><b>postalias</b>(1)</a> command can query any supported file type, but + it can create only the following file types: + + <b>btree</b> The output 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> databases. + + <b>cdb</b> The output is 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> databases. + + <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>. This is available on systems with support + for <b>dbm</b> databases. + + <b>fail</b> A table that reliably fails all requests. The lookup ta- + ble name is used for logging only. This table exists to + simplify Postfix error tests. + + <b>hash</b> The output is a hashed file, named <i>file</i><b>_</b><i>name</i><b>.db</b>. This is + available on systems with support for <b>db</b> databases. + + <b>lmdb</b> The output is a btree-based file, named <i>file</i><b>_</b><i>name</i><b>.lmdb</b>. + <b>lmdb</b> supports concurrent writes and reads from different + processes, unlike other supported file-based tables. + This is available on systems with support for <b>lmdb</b> data- + bases. + + <b>sdbm</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>. This is available on systems with support + for <b>sdbm</b> databases. + + When no <i>file</i><b>_</b><i>type</i> is specified, the software uses the database + type specified via the <b><a href="postconf.5.html#default_database_type">default_database_type</a></b> configuration + parameter. The default value for this parameter depends on the + host environment. + + <i>file</i><b>_</b><i>name</i> + The name of the alias database source file when creating a data- + base. + +<b>DIAGNOSTICS</b> + Problems are logged to the standard error stream and to <b>syslogd</b>(8) or + <a href="postlogd.8.html"><b>postlogd</b>(8)</a>.
