NISPLUS_TABLE(5) File Formats Manual NISPLUS_TABLE(5)

nisplus_table - Postfix NIS+ client

postmap -q "string" "nisplus:[name=%s];name.name."
postmap -q - "nisplus:[name=%s];name.name." <inputfile


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.


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:


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.
