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.
