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:

       ·      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.

       ·      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.

       ·      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.
