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.
