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.
