Postfix NIS+ client
"SYNOPSIS"
postmap -q "string" "nisplus:[name=%s];name.name." postmap -q - "nisplus:[name=%s];name.name." <inputfileThe 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.DESCRIPTION
"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:
\(bu
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.
\(bu
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.
\(bu
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.:1This queries the local aliases file before the NIS+ file.
