NAMEnisplus_table - Postfix NIS+ client
postmap -q "string" "nisplus:[name=%s];name.name." postmap -q - "nisplus:[name=%s];name.name." <inputfile
DESCRIPTIONThe 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.
QUERY SYNTAXMost of the NIS+ query is specified via the NIS+ map name. The general format of a Postfix NIS+ map name is as follows:
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.
EXAMPLEA NIS+ aliases map might be queried as follows:
alias_maps = dbm:/etc/mail/aliases, nisplus:[alias=%s];mail_aliases.org_dir.$mydomain.:1
