+Replacements for Deprecated Features</h1>
+
+<hr>
+
+<h2>Purpose of this document </h2>
+
+<p> This document describes Postfix features that are deprecated
+(will be removed) or that have already been removed. It also has
+tips for making an existing Postfix configuration more future-proof.
+</p>
+
+<p> Overview: </p>
+
+<ul>
+
+<li> <a href="#why"> Why deprecate? </a>
+
+<li> <a href="#process"> Deprecation process </a>
+
+<li> <a href="#features"> Deprecated features </a>
+
+</ul>
+
+<h2> <a name="why"> Why deprecate? </a> </h2>
+
+<p> Sometimes, a Postfix feature needs to be replaced with a different
+one. To give an example: </p>
+
+<ul>
+
+<li> <p> The initial Postfix TLS implementation used multiple boolean
+parameters: one parameter to enable opportunistic TLS (for example,
+"<a href="postconf.5.html#smtp_enforce_tls">smtp_enforce_tls</a> = yes") and one parameter to enable mandatory TLS
+(for example, "smtp_require_tls = yes"). </p>
+
+<li> <p> As we added support more features such as fingerprint,
+dane, and so on, we decided not to add more boolean parameters.
+Instead we introduced one configuration parameter to select from
+multiple deployment models (for example, <a href="postconf.5.html#smtp_tls_security_level">smtp_tls_security_level</a> =
+may | encrypt | dane, etc...). </p>
+
+</ul>
+
+<!--
+
+<p> Over time it has become clear that 'level' is too rigid, so this may
+have to change again. Wietse and Viktor have been discussing a way to
+specify a range with minimum properties that are required (e.g., encrypt)
+and nice-to-have properties if they are available (dane or mta-sts). </p>
+
+-->
+
+<p> Having both the "old" and "new" way to configure Postfix is
+convenient for existing Postfix installations, because their
+configuration does not break after an upgrade to a new version.
+Unfortunately, there are also disadvantages. Having multiple ways
+to do similar things is not only confusing for newcomers, it also
+makes Postfix harder to change. </p>
+
+<h2> <a name="process"> Deprecation process </a> </h2>
+
+<p> The basic process steps are: </p>
+
+<ol>
+
+<li> <p> Inform humans that a feature will be removed, and suggest
+replacements, in logging and documentation. </p>
+
+<li> <p> Remove the feature, and update logging and documentation. </p>
+
+</ol>
+
+<p> Disclaimer: it has taken 20 years for some features to be
+removed. This past is not a guarantee for the future. </p>

+<h2>MongoDB Support in Postfix</h2>
+
+<p> Postfix can use MongoDB as a source for any of its lookups:
+<a href="aliases.5.html">aliases(5)</a>, <a href="virtual.5.html">virtual(5)</a>, <a href="canonical.5.html">canonical(5)</a>, etc. This allows you to keep
+information for your mail service in a replicated noSQL database
+with fine-grained access controls. By not storing it locally on the
+mail server, the administrators can maintain it from anywhere, and
+the users can control whatever bits of it you think appropriate.
+You can have multiple mail servers using the same information,
+without the hassle and delay of having to copy it to each. </p>

+
+<h2><a name="build">Building Postfix with MongoDB support</a></h2>
+
+<p>These instructions assume that you build Postfix from source
+code as described in the <a href="INSTALL.html">INSTALL</a> document. Some modification may
+be required if you build Postfix from a vendor-specific source
+package. </p>
+
+<p>The Postfix MongoDB client requires the <b>mongo-c-driver</b>
+library. This can be built from source code from <a
+href="https://github.com/mongodb/mongo-c-driver/releases">the
+mongod-c project</a>, or this can be installed as a binary package
+from your OS distribution, typically named <b>mongo-c-driver</b>,
+<b>mongo-c-driver-devel</b> or <b>libmongoc-dev</b>.
+Installing the mongo-c-driver library may also install <b>libbson</b>
+as a dependency. </p>
+
+<p> To build Postfix with mongodb map support, add to the CCARGS
+environment variable the options -DHAS_MONGODB and -I for the
+directory containing the mongodb headers, and specify the <a href="MONGODB_README.html">AUXLIBS_MONGODB</a>
+with the libmongoc and libbson libraries, for example:</p>
+
+<blockquote>
+<pre>
+% make tidy
+% make -f Makefile.init makefiles \
+ CCARGS="$CCARGS -DHAS_MONGODB -I/usr/include/libmongoc-1.0 \
+ -I/usr/include/libbson-1.0" \
+ <a href="MONGODB_README.html">AUXLIBS_MONGODB</a>="-lmongoc-1.0 -lbson-1.0"
+</pre>
+</blockquote>
+
+<p>The 'make tidy' command is needed only if you have previously
+built Postfix without MongoDB support. </p>
+
+<p>If your MongoDB shared library is in a directory that the RUN-TIME
+linker does not know about, add a "-Wl,-R,/path/to/directory" option
+after "-lbson-1.0". Then, just run 'make'.</p>
+
+<h2><a name="config">Configuring MongoDB lookups</a></h2>
+
+<p> In order to use MongoDB lookups, define a MongoDB source as a
+table lookup in <a href="postconf.5.html">main.cf</a>, for example: </p>
+
+<blockquote>
+<pre>
+<a href="postconf.5.html#alias_maps">alias_maps</a> = <a href="DATABASE_README.html#types">hash</a>:/etc/aliases, <a href="proxymap.8.html">proxy</a>:<a href="mongodb_table.5.html">mongodb</a>:/etc/postfix/mongo-aliases.cf
+</pre>
+</blockquote>
+
+<p> The file /etc/postfix/mongo-aliases.cf can specify a number of
+parameters. For a complete description, see the <a href="mongodb_table.5.html">mongodb_table(5)</a>
+manual page. </p>
+
+<h2><a name="example_virtual">Example: virtual(5) alias maps</a></h2>
+
+<p> Here's a basic example for using MongoDB to look up <a href="virtual.5.html">virtual(5)</a>
+aliases. Assume that in <a href="postconf.5.html">main.cf</a>, you have: </p>
+
+<blockquote>
+<pre>
+<a href="postconf.5.html#virtual_alias_maps">virtual_alias_maps</a> = <a href="DATABASE_README.html#types">hash</a>:/etc/postfix/virtual_aliases,
+ <a href="proxymap.8.html">proxy</a>:<a href="mongodb_table.5.html">mongodb</a>:/etc/postfix/mongo-virtual-aliases.cf
+</pre>
+</blockquote>
+
+<p> and in <a href="mongodb_table.5.html">mongodb</a>:/etc/postfix/mongo-virtual-aliases.cf you have: </p>
+
+<blockquote>
+<pre>
+uri = mongodb+srv://user_name:password@some_server
+dbname = mail
+collection = mailbox
+query_filter = {"$or": [{"username":"%s"}, {"alias.address": "%s"}], "active": 1}
+result_attribute = username
+</pre>
+</blockquote>
+
+<p>This example assumes mailbox names are stored in a MongoDB backend,
+in a format like:</p>
+
+<blockquote>
+<pre>
+{ "username": "user@example.com",
+ "alias": [
+ {"address": "admin@example.com"},
+ {"address": "abuse@example.com"}
+ ],
+ "active": 1
+}
+</pre>
+</blockquote>
+
+<p>Upon receiving mail for "admin@example.com" that isn't found in the
+/etc/postfix/virtual_aliases database, Postfix will search the
+MongoDB server/cluster listening at port 27017 on some_server. It
+will connect using the provided credentials, and search for any
+entries whose username is, or alias field has "admin@example.com".
+It will return the username attribute of those found, and build a
+list of their email addresses. </p>
+
+<p> Notes: </p>
+
+<ul>
+
+<li><p> As with <b>projection</b> (see below), the Postfix mongodb
+client automatically removes the top-level '_id' field from a
+result_attribute result. </p> </li>
+
+<li><p> The Postfix mongodb client will only parse result fields
+with data types UTF8, INT32, INT64 and ARRAY. Other fields will be
+ignored, with a warning in the logs. </p> </li>
+
+</ul>
+
+<h2><a name="example_mailing_list">Example: Mailing lists</a></h2>
+
+<p>When it comes to mailing lists, one way of implementing one would
+be as below:</p>
+
+<blockquote>
+<pre>
+{ "name": "dev@example.com", "active": 1, "address":
+ [ "hamid@example.com", "wietse@example.com", "viktor@example.com" ] }
+</pre>
+</blockquote>
+
+<p>using the filter below, will result in a comma separated string
+with all email addresses in this list. </p>
+
+<blockquote>
+<pre>
+query_filter = {"name": "%s", "active": 1}
+result_attribute = address
+</pre>
+</blockquote>
+
+<p> Notes: </p>
+
+<ul>
+
+<li><p> As with <b>projection</b> (see below), the Postfix mongodb
+client automatically removes the top-level '_id' field from a
+result_attribute result. </p> </li>
+
+<li><p> The Postfix mongodb client will only parse result fields
+with data types UTF8, INT32, INT64 and ARRAY. Other fields will be
+ignored, with a warning in the logs. </p> </li>
+
+</ul>
+
+<h2><a name="example_projections">Example: advanced projections</a></h2>
+
+<p>This module also supports the use of more complex MongoDB
+projections. There may be some use cases where operations such as
+concatenation are necessary to be performed on the data retrieved
+from the database. Although it is encouraged to keep the database
+design simple enough so this is not necessary, postfix supports the
+use of MongoDB projections to achieve the goal. </p>
+
+<p>Consider the example below:</p>
+
+<blockquote>
+<pre>
+{ "username": "user@example.com",
+ "local_part": "user",
+ "domain": "example.com",
+ "alias": [
+ {"address": "admin@example.com"},
+ {"address": "abuse@example.com"}
+ ],
+ "active": 1
+}
+</pre>
+</blockquote>
+
+<p><a href="postconf.5.html#virtual_mailbox_maps">virtual_mailbox_maps</a> can be created using below parameters in a
+<a href="mongodb_table.5.html">mongodb</a>:/etc/postfix/mongo-virtual-mailboxes.cf file:</p>
+
+<blockquote>
+<pre>
+uri = mongodb+srv://user_name:password@some_server
+dbname = mail
+collection = mailbox
+query_filter = {"$or": [{"username":"%s"}, {"alias.address": "%s"}], "active": 1}
+projection = { "mail_path": {"$concat": ["$domain", "/", "$local_part"]} }
+</pre>
+</blockquote>
+
+<p>This will return 'example.com/user' path built from the database fields. </p>
+
+<p>A couple of considerations when using projections:</p>
+
+<ul>
+
+<li><p>As with <b>result_attribute</b>, the Postfix mongodb client
+automatically removes the top-level '_id' field from a projection
+result. </p></li>
+
+<li><p> The Postfix mongodb client will only parse fields with data
+types UTF8, INT32, INT64 and ARRAY. Other fields will be ignored,
+with a warning in the logs. It is suggested to exclude any unnecessary
+fields when using a projection. </p></li>
+
+</ul>
+
+<h2><a name="feedback">Feedback</a></h2>
+
+<p> If you have questions, send them to postfix-users@postfix.org.
+Please include relevant information about your Postfix setup:
+MongoDB-related output from postconf, which libraries you built
+with, and such. If your question involves your database contents,
+please include the applicable bits of some database entries. </p>
+
+<h2><a name="credits">Credits</a></h2>

<b>SYNOPSIS</b>

+
<b>DESCRIPTION</b>
The Postfix SMTP+LMTP client implements the SMTP and LMTP mail delivery
protocols. It processes message delivery requests from the queue man-
ager. Each request specifies a queue file, a sender address, a domain
or host to deliver to, and recipient information. This program expects
- to be run from the <a href="master.8.html"><b>master</b>(8)</a> process manager.
+ to be run from the <a href="master.8.html"><b>master</b>(8)</a> process manager. The process name, <b>smtp</b> or
+ <b>lmtp</b>, controls the protocol, and the names of the configuration parame-
+ ters that will be used.
The SMTP+LMTP client updates the queue file and marks recipients as
finished, or it informs the queue manager that delivery should be tried
again at a later time. Delivery status reports are sent to the
<a href="bounce.8.html"><b>bounce</b>(8)</a>, <a href="defer.8.html"><b>defer</b>(8)</a> or <a href="trace.8.html"><b>trace</b>(8)</a> daemon as appropriate.
- The SMTP+LMTP client looks up a list of mail exchanger addresses for
- the destination host, sorts the list by preference, and connects to
- each listed address until it finds a server that responds.
-
- When a server is not reachable, or when mail delivery fails due to a
- recoverable error condition, the SMTP+LMTP client will try to deliver
- the mail to an alternate host.
+ The server lookup strategy is different for SMTP and LMTP, as described
+ in the sections "SMTP SERVER LOOKUP" and "LMTP SERVER LOOKUP".
- After a successful mail transaction, a connection may be saved to the

+
+<b>NAME</b>
+ mongodb_table - Postfix MongoDB client configuration
+
+<b>SYNOPSIS</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> &lt;<i>inputfile</i>
+
+<b>DESCRIPTION</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>MONGODB PARAMETERS</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>

+ resolve. Please see:

+
+ 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>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>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 '$$'.

<b>SYNOPSIS</b>

+
<b>DESCRIPTION</b>
The Postfix SMTP+LMTP client implements the SMTP and LMTP mail delivery
protocols. It processes message delivery requests from the queue man-
ager. Each request specifies a queue file, a sender address, a domain
or host to deliver to, and recipient information. This program expects
- to be run from the <a href="master.8.html"><b>master</b>(8)</a> process manager.
+ to be run from the <a href="master.8.html"><b>master</b>(8)</a> process manager. The process name, <b>smtp</b> or
+ <b>lmtp</b>, controls the protocol, and the names of the configuration parame-
+ ters that will be used.
The SMTP+LMTP client updates the queue file and marks recipients as
finished, or it informs the queue manager that delivery should be tried
again at a later time. Delivery status reports are sent to the
<a href="bounce.8.html"><b>bounce</b>(8)</a>, <a href="defer.8.html"><b>defer</b>(8)</a> or <a href="trace.8.html"><b>trace</b>(8)</a> daemon as appropriate.
- The SMTP+LMTP client looks up a list of mail exchanger addresses for
- the destination host, sorts the list by preference, and connects to
- each listed address until it finds a server that responds.
-
- When a server is not reachable, or when mail delivery fails due to a
- recoverable error condition, the SMTP+LMTP client will try to deliver
- the mail to an alternate host.
+ The server lookup strategy is different for SMTP and LMTP, as described
+ in the sections "SMTP SERVER LOOKUP" and "LMTP SERVER LOOKUP".
- After a successful mail transaction, a connection may be saved to the
