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.
