# NAME

|
# nisplus_table 5
|
|
# SUMMARY
|
|
# Postfix NIS+ client
|
|
# SYNOPSIS
|
|
# \fBpostmap -q "\fIstring\fB" "nisplus:[\fIname\fB=%s];\fIname.name.\fB"\fR
|
|
#
|
|
# \fBpostmap -q - "nisplus:[\fIname\fB=%s];\fIname.name.\fB"\fR <\fIinputfile\fR
|
|
# DESCRIPTION
|
|
# The Postfix mail system uses optional lookup tables.
|
|
# These tables are usually in \fBdbm\fR or \fBdb\fR format.
|
|
# Alternatively, lookup tables can be specified as NIS+
|
|
# databases.
|
|
#
|
|
# To find out what types of lookup tables your Postfix system
|
|
# supports use the "\fBpostconf -m\fR" command.
|
|
#
|
|
# To test Postfix NIS+ lookup tables, use the "\fBpostmap -q\fR"
|
|
# command as described in the SYNOPSIS above.
|
|
# QUERY SYNTAX
|
|
# .ad
|
|
# .fi
|
|
# Most of the NIS+ query is specified via the NIS+ map name. The
|
|
# general format of a Postfix NIS+ map name is as follows:
|
|
#
|
|
# .ti +4
|
|
# \fBnisplus:[\fIname\fB=%s];\fIname.name.name\fB.:\fIcolumn\fR
|
|
#
|
|
# Postfix NIS+ map names differ from what one normally
|
|
# would use with commands such as \fBniscat\fR:
|
|
# .IP \(bu
|
|
# With each NIS+ table lookup, "\fB%s\fR" is replaced by a
|
|
# version of the lookup string. There can be only one
|
|
# "\fB%s\fR" instance in a Postfix NIS+ map name.
|
|
# .IP \(bu
|
|
# Postfix NIS+ map names use "\fB;\fR" instead of "\fB,\fR",
|
|
# because the latter character is special in the Postfix
|
|
# main.cf file. Postfix replaces "\fB;\fR" characters in
|
|
# the map name by "\fB,\fR" before making NIS+ queries.
|
|
# .IP \(bu
|
|
# The ":\fIcolumn\fR" 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 ":\fIcolumn\fR" is specified the first column (1) is used.
|
|
# EXAMPLE
|
|
# A NIS+ aliases map might be queried as follows:
|
|
#
|
|
# .ti +4
|
|
# alias_maps = dbm:/etc/mail/aliases,
|
|
# .ti +2
|
|
# nisplus:[alias=%s];mail_aliases.org_dir.$mydomain.:1
|
|
# .ad
|
|
# .fi
|
|
#
|
|
# This queries the local aliases file before the NIS+ file.
