MONGODB_TABLE(5) MONGODB_TABLE(5)
<b><a name="name">NAME</a></b>
mongodb_table - Postfix MongoDB client configuration
<b><a name="synopsis">SYNOPSIS</a></b>
<b>postmap -q "</b><i>string</i><b>" <a href="mongodb_table.5.html">mongodb</a>:/etc/postfix/</b><i>filename</i>
<b>postmap -q - <a href="mongodb_table.5.html">mongodb</a>:/etc/postfix/</b><i>filename</i> <<i>inputfile</i>
<b><a name="description">DESCRIPTION</a></b>
The Postfix mail system uses optional tables for address rewriting or
mail routing. These tables are usually in <b>dbm</b> or <b>db</b> format.
Alternatively, lookup tables can be specified as MongoDB databases. In
order to use MongoDB lookups, define a MongoDB source as a lookup table
in <a href="postconf.5.html">main.cf</a>, for example:
<a href="postconf.5.html#alias_maps">alias_maps</a> = <a href="mongodb_table.5.html">mongodb</a>:/etc/postfix/mongodb-aliases.cf
In this example, the file /etc/postfix/mongodb-aliases.cf has the same
format as the Postfix <a href="postconf.5.html">main.cf</a> file, and can specify the parameters
described below. It is also possible to have the configuration in
<a href="postconf.5.html">main.cf</a>; see "OBSOLETE MAIN.CF PARAMETERS" below.
It is strongly recommended to use <a href="proxymap.8.html">proxy</a>:mongodb, in order to reduce the
number of database connections. For example:
<a href="postconf.5.html#alias_maps">alias_maps</a> = <a href="proxymap.8.html">proxy</a>:<a href="mongodb_table.5.html">mongodb</a>:/etc/postfix/mongodb-aliases.cf
Note: when using <a href="proxymap.8.html">proxy</a>:<a href="mongodb_table.5.html">mongodb</a>:/<i>file</i>, the file must be readable by the
unprivileged postfix user (specified with the Postfix <a href="postconf.5.html#mail_owner">mail_owner</a> con-
figuration parameter).
<b><a name="mongodb_parameters">MONGODB PARAMETERS</a></b>
<b>uri</b> The URI of mongo server/cluster that Postfix will try to connect
to and query from. Please see
<a href="https://www.mongodb.com/docs/manual/reference/connection-string/">https://www.mongodb.com/docs/manual/reference/connection-string/</a>
Example:
uri = mongodb+srv://user:pass@loclhost:27017/mail
<b>dbname</b> Name of the database to read the information from. Example:
dbname = mail
<b>collection</b>
Name of the collection (table) to read the information from.
Example:
collection = mailbox
<b>query_filter</b>
The MongoDB query template used to search the database, where <b>%s</b>
is a substitute for the email address that Postfix is trying to
resolve. Please see:
<a href="https://www.mongodb.com/docs/manual/tutorial/query-documents/">https://www.mongodb.com/docs/manual/tutorial/query-documents/</a>
Example:
query_filter = {"$or": [{"username": "%s"}, {"alias.address": "%s"}], "active": 1}
This parameter supports the following '%' expansions:
<b>%%</b> This is replaced by a literal '%' character.
<b>%s</b> This is replaced by the input key. The %s must appear in
quotes, because all Postfix queries are strings contain-
ing (parts from) a domain or email address. Postfix makes
no numerical queries.
<b>%u</b> When the input key is an address of the form user@domain,
<b>%u</b> is replaced by the local part of the address. Other-
wise, <b>%u</b> is replaced by the entire search string.
<b>%d</b> When the input key is an address of the form user@domain,
<b>%d</b> is replaced by the domain part of the address.
<b>%[1-9]</b> The patterns %1, %2, ... %9 are replaced by the corre-
sponding most significant component of the input key's
domain. If the input key is <i>user@mail.example.com</i>, then
%1 is <b>com</b>, %2 is <b>example</b> and %3 is <b>mail</b>.
In the above substitutions, characters will be quoted as
required by <a href="https://tools.ietf.org/html/rfc4627">RFC 4627</a>. For example, each double quote or back-
slash character will be escaped with a backslash characacter.
<b>projection</b>
Advanced MongoDB query projections. Please see:
<a href="https://www.mongodb.com/docs/manual/tutorial/project-fields-from-query-results/">https://www.mongodb.com/docs/manual/tutorial/project-fields-from-query-results/</a>
<b>o</b> If <b>projection</b> is non-empty, then <b>result_attribute</b> must be
empty.
<b>o</b> This implementation can extract information only from
result fields that have type <b>string</b> (UTF8), <b>integer</b>
(int32, int64) and <b>array</b>. Other result fields will be
ignored with a warning. Please see:
<a href="https://mongoc.org/libbson/current/bson_type_t.html">https://mongoc.org/libbson/current/bson_type_t.html</a>
<b>o</b> As with <b>result_attribute</b>, the top-level _id field (type
OID) is automatically removed from projection results.
<b>result_attribute</b>
Comma or whitespace separated list with the names of fields to
be returned in a lookup result.
<b>o</b> If <b>result_attribute</b> is non-empty, then <b>projection</b> must be
empty.
<b>o</b> As with <b>projection</b>, the top-level _id field (type OID) is
automatically removed from lookup results.
<b>result_format (default: %s</b>)
Format template applied to the result from <b>projection</b> or
<b>result_attribute</b>. Most commonly used to append (or prepend) text
to the result. This parameter supports the following '%' expan-
sions:
<b>%%</b> This is replaced by a literal '%' character.
<b>%s</b> This is replaced by the value of the result attribute.
When result is empty it is skipped.
<b>%u</b> When the result attribute value is an address of the form
user@domain, <b>%u</b> is replaced by the local part of the
address. When the result has an empty localpart it is
skipped.
<b>%d</b> When a result attribute value is an address of the form
user@domain, <b>%d</b> is replaced by the domain part of the
attribute value. When the result is unqualified it is
skipped.
<b>%[SUD1-9]</b>
The upper-case and decimal digit expansions interpolate
the parts of the input key rather than the result. Their
behavior is identical to that described with <b>query_fil-</b>
<b>ter</b>, and in fact because the input key is known in
advance, lookups whose key does not contain all the
information specified in the result template are sup-
pressed and return no results.
For example, using "result_format = <a href="smtp.8.html">smtp</a>:[%s]" allows one to use
a mailHost attribute as the basis of a <a href="transport.5.html">transport(5)</a> table. After
applying the result format, multiple values are concatenated as
comma separated strings. The expansion_limit parameter explained
below allows one to restrict the number of values in the result,
which is especially useful for maps that should return a single
value.
The default value <b>%s</b> specifies that each attribute value should
be used as is.
NOTE: DO NOT put quotes around the result format! The result is
not a JSON string.
<b>domain (default: no domain list)</b>
This is a list of domain names, paths to files, or "<a href="DATABASE_README.html">type:table</a>"
databases. When specified, only fully qualified search keys with
a *non-empty* localpart and a matching domain are eligible for
lookup: 'user' lookups, bare domain lookups and "@domain"
lookups are not performed. This can significantly reduce the
query load on the backend database. Example:
domain = postfix.org, <a href="DATABASE_README.html#types">hash</a>:/etc/postfix/searchdomains
<b>expansion_limit (default: 0)</b>
A limit on the total number of result elements returned (as a
comma separated list) by a lookup against the map. A setting of
zero disables the limit. Lookups fail with a temporary error if
the limit is exceeded. Setting the limit to 1 ensures that
lookups do not return multiple values.
<b>OBSOLETE MAIN.CF PARAMETERS</b>
MongoDB parameters can also be defined in <a href="postconf.5.html">main.cf</a>. Specify as MongoDB
source a name that doesn't begin with a slash or a dot. The MongoDB
parameters will then be accessible as the name you've given the source
in its definition, an underscore, and the name of the parameter. For
example, if a map is specified as "<a href="mongodb_table.5.html">mongodb</a>:<i>mongodb</i><b>_</b><i>source</i>", the "uri"
parameter would be defined in <a href="postconf.5.html">main.cf</a> as "<i>mongodb</i><b>_</b><i>source</i>_uri".
Note: with this form, passwords are written in <a href="postconf.5.html">main.cf</a>, which is nor-
mally world-readable, and '$' in a mongodb parameter setting needs to
be written as '$$'.
