<b><a name="description">DESCRIPTION</a></b>
|
|
The Postfix mail system uses optional lookup tables. These tables are
|
|
usually in <b>dbm</b> or <b>db</b> format. Alternatively, lookup tables can be spec-
|
|
ified as NIS+ databases.
|
|
|
|
To find out what types of lookup tables your Postfix system supports
|
|
use the "<b>postconf -m</b>" command.
|
|
|
|
To test Postfix NIS+ lookup tables, use the "<b>postmap -q</b>" command as
|
|
described in the SYNOPSIS above.
|
|
|
|
<b><a name="query_syntax">QUERY SYNTAX</a></b>
|
|
Most of the NIS+ query is specified via the NIS+ map name. The general
|
|
format of a Postfix NIS+ map name is as follows:
|
|
|
|
<b><a href="nisplus_table.5.html">nisplus</a>:[</b><i>name</i><b>=%s];</b><i>name.name.name</i><b>.:</b><i>column</i>
|
|
|
|
Postfix NIS+ map names differ from what one normally would use with
|
|
commands such as <b>niscat</b>:
|
|
|
|
<b>o</b> With each NIS+ table lookup, "<b>%s</b>" is replaced by a version of
|
|
the lookup string. There can be only one "<b>%s</b>" instance in a
|
|
Postfix NIS+ map name.
|
|
|
|
<b>o</b> Postfix NIS+ map names use "<b>;</b>" instead of "<b>,</b>", because the lat-
|
|
ter character is special in the Postfix <a href="postconf.5.html">main.cf</a> file. Postfix
|
|
replaces "<b>;</b>" characters in the map name by "<b>,</b>" before making
|
|
NIS+ queries.
|
|
|
|
<b>o</b> The ":<i>column</i>" part in the NIS+ map name is not part of the
|
|
actual NIS+ query. Instead, it specifies the number of the table
|
|
column that provides the lookup result. When no ":<i>column</i>" is
|
|
specified the first column (1) is used.
|
|
|
|
<b><a name="example">EXAMPLE</a></b>
|
|
A NIS+ aliases map might be queried as follows:
|
|
|
|
<a href="postconf.5.html#alias_maps">alias_maps</a> = <a href="DATABASE_README.html#types">dbm</a>:/etc/mail/aliases,
|
|
<a href="nisplus_table.5.html">nisplus</a>:[alias=%s];mail_aliases.org_dir.$<a href="postconf.5.html#mydomain">mydomain</a>.:1
|
|
|
|
This queries the local aliases file before the NIS+ file.
