NISPLUS_TABLE(5)						File Formats Manual						  NISPLUS_TABLE(5)

NAME

       nisplus_table - Postfix NIS+ client

SYNOPSIS

       postmap -q "string" "nisplus:[name=%s];name.name."

       postmap -q - "nisplus:[name=%s];name.name." <inputfile

DESCRIPTION

       The  Postfix  mail  system uses optional lookup tables.	These tables are usually in dbm or db format.  Alternatively, lookup tables can be
       specified as NIS+ databases.

       To find out what types of lookup tables your Postfix system supports use the "postconf -m" command.

       To test Postfix NIS+ lookup tables, use the "postmap -q" command as described in the SYNOPSIS above.

QUERY SYNTAX

       Most of the NIS+ query is specified via the NIS+ map name. The general format of a Postfix NIS+ map name is as follows:

	   nisplus:[name=%s];name.name.name.:column

       Postfix NIS+ map names differ from what one normally would use with commands such as niscat:

       o      With each NIS+ table lookup, "%s" is replaced by a version of the lookup string.	There can be only one "%s" instance in	a  Postfix
	      NIS+ map name.

       o      Postfix  NIS+  map  names  use  ";"  instead  of	",", because the latter character is special in the Postfix main.cf file.  Postfix
	      replaces ";" characters in the map name by "," before making NIS+ queries.

       o      The ":column" 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 ":column" is specified the first column (1) is used.

EXAMPLE

       A NIS+ aliases map might be queried as follows:

	   alias_maps = dbm:/etc/mail/aliases,
	       nisplus:[alias=%s];mail_aliases.org_dir.$mydomain.:1

       This queries the local aliases file before the NIS+ file.
