# 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" <\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:
#
# .fi
# \fBnisplus:[\fIname\fB=%s];\fIname.name.name\fB.:\fIcolumn\fR
# .fi
#
# 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
# .ad
# .fi
# A NIS+ aliases map might be queried as follows:
#
# .nf
# alias_maps = dbm:/etc/mail/aliases,
# nisplus:[alias=%s];mail_aliases.org_dir.$mydomain.:1
# .fi
#
# This queries the local aliases file before the NIS+ file.
# SEE ALSO
# postmap(1), Postfix lookup table manager
# README FILES
# .ad
# .fi
# Use "\fBpostconf readme_directory\fR" or
# "\fBpostconf html_directory\fR" to locate this information.
