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 spec-
       ified 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 lat-
              ter 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.
