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.
