+# NAME
+#	mysql_table 5
+# SUMMARY
+#	Postfix MySQL client configuration
+# SYNOPSIS
+#	\fBpostmap -q "\fIstring\fB" mysql:/etc/postfix/\fIfilename\fR
+#
+#	\fBpostmap -q - mysql:/etc/postfix/\fIfilename\fB <\fIinputfile\fR
+# DESCRIPTION
+#	The Postfix mail system uses optional tables for address
+#	rewriting or mail routing. These tables are usually in
+#	\fBdbm\fR or \fBdb\fR format.
+#
+#	Alternatively, lookup tables can be specified as MySQL databases.
+#	In order to use MySQL lookups, define a MySQL source as a lookup
+#	table in main.cf, for example:
+# .nf
+#	    alias_maps = mysql:/etc/mysql-aliases.cf
+# .fi
+#
+#	The file /etc/postfix/mysql-aliases.cf has the same format as
+#	the Postfix main.cf file, and can specify the parameters
+#	described below.
+# LIST MEMBERSHIP
+# .ad
+# .fi
+#	When using SQL to store lists such as $mynetworks,
+#	$mydestination, $relay_domains, $local_recipient_maps,
+#	etc., it is important to understand that the table must
+#	store each list member as a separate key. The table lookup
+#	verifies the *existence* of the key. See "Postfix lists
+#	versus tables" in the DATABASE_README document for a
+#	discussion.
+#
+#	Do NOT create tables that return the full list of domains
+#	in $mydestination or $relay_domains etc., or IP addresses
+#	in $mynetworks.
+#
+#	DO create tables with each matching item as a key and with
+#	an arbitrary value. With SQL databases it is not uncommon to
+#	return the key itself or a constant value.
+# MYSQL PARAMETERS
+# .ad
+# .fi
+# .IP "\fBhosts\fR"
+#	The hosts that Postfix will try to connect to and query from.
+#	Specify \fIunix:\fR for UNIX domain sockets, \fIinet:\fR for TCP
+#	connections (default).  Example:
+# .nf
+#	    hosts = host1.some.domain host2.some.domain:port
+#	    hosts = unix:/file/name
+# .fi
+#
+#	The hosts are tried in random order, with all connections over
+#	UNIX domain sockets being tried before those over TCP.	The
+#	connections are automatically closed after being idle for about
+#	1 minute, and are re-opened as necessary. Postfix versions 2.0
+#	and earlier do not randomize the host order.
+#
+#	NOTE: if you specify localhost as a hostname (even if you
+#	prefix it with \fIinet:\fR), MySQL will connect to the default
+#	UNIX domain socket.  In order to instruct MySQL to connect to
+#	localhost over TCP you have to specify
+# .nf
+#	    hosts = 127.0.0.1
+# .fi
+# .IP "\fBuser, password\fR"
+#	The user name and password to log into the mysql server.
+#	Example:
+# .nf
+#	    user = someone
+#	    password = some_password
+# .fi
+# .IP "\fBdbname\fR"
+#	The database name on the servers. Example:
+# .nf
+#	    dbname = customer_database
+# .fi
+# .IP "\fBquery\fR"
+#	The SQL query template used to search the database, where \fB%s\fR
+#	is a substitute for the address Postfix is trying to resolve,
+#	e.g.
+# .nf
+#	    query = SELECT replacement FROM aliases WHERE mailbox = '%s'
+# .fi
+#
+#	By default, every query must return a result set (instead
+#	of storing its results in a table); with "\fBrequire_result_set
+#	= no\fR" (Postfix 3.2 and later), the absence of a result
+#	set is treated as "not found".
+#
+#	This parameter supports the following '%' expansions:
+# .RS
+# .IP "\fB%%\fR"
+#	This is replaced by a literal '%' character.
+# .IP "\fB%s\fR"
+#	This is replaced by the input key.
+#	SQL quoting is used to make sure that the input key does not
+#	add unexpected metacharacters.
+# .IP "\fB%u\fR"
+#	When the input key is an address of the form user@domain, \fB%u\fR
+#	is replaced by the SQL quoted local part of the address.
+#	Otherwise, \fB%u\fR is replaced by the entire search string.
+#	If the localpart is empty, the query is suppressed and returns
+#	no results.
+# .IP "\fB%d\fR"
+#	When the input key is an address of the form user@domain, \fB%d\fR
+#	is replaced by the SQL quoted domain part of the address.
+#	Otherwise, the query is suppressed and returns no results.
+# .IP "\fB%[SUD]\fR"
+#	The upper-case equivalents of the above expansions behave in the
+#	\fBquery\fR parameter identically to their lower-case counter-parts.
+#	With the \fBresult_format\fR parameter (see below), they expand the
+#	input key rather than the result value.
+# .IP "\fB%[1-9]\fR"
+#	The patterns %1, %2, ... %9 are replaced by the corresponding
+#	most significant component of the input key's domain. If the
+#	input key is \fIuser@mail.example.com\fR, then %1 is \fBcom\fR,
+#	%2 is \fBexample\fR and %3 is \fBmail\fR. If the input key is
+#	unqualified or does not have enough domain components to satisfy
+#	all the specified patterns, the query is suppressed and returns
+#	no results.
+# .RE
+# .IP
+#	The \fBdomain\fR parameter described below limits the input
+#	keys to addresses in matching domains. When the \fBdomain\fR
+#	parameter is non-empty, SQL queries for unqualified addresses
+#	or addresses in non-matching domains are suppressed
+#	and return no results.
+#
+#	This parameter is available with Postfix 2.2. In prior releases
+#	the SQL query was built from the separate parameters:
+#	\fBselect_field\fR, \fBtable\fR, \fBwhere_field\fR and
+#	\fBadditional_conditions\fR. The mapping from the old parameters
+#	to the equivalent query is:
+#
+# .nf
+#	    SELECT [\fBselect_field\fR]
+#	    FROM [\fBtable\fR]
+#	    WHERE [\fBwhere_field\fR] = '%s'
+#	          [\fBadditional_conditions\fR]
+# .fi
+#
+#	The '%s' in the \fBWHERE\fR clause expands to the escaped search string.
+#	With Postfix 2.2 these legacy parameters are used if the \fBquery\fR
+#	parameter is not specified.
+#
+#	NOTE: DO NOT put quotes around the query parameter.
+# .IP "\fBresult_format (default: \fB%s\fR)\fR"
+#	Format template applied to result attributes. Most commonly used
+#	to append (or prepend) text to the result. This parameter supports
+#	the following '%' expansions:
+# .RS
+# .IP "\fB%%\fR"
+#	This is replaced by a literal '%' character.
+# .IP "\fB%s\fR"
+#	This is replaced by the value of the result attribute. When
+#	result is empty it is skipped.
+# .IP "\fB%u\fR
+#	When the result attribute value is an address of the form
+#	user@domain, \fB%u\fR is replaced by the local part of the
+#	address. When the result has an empty localpart it is skipped.
+# .IP "\fB%d\fR"
+#	When a result attribute value is an address of the form
+#	user@domain, \fB%d\fR is replaced by the domain part of
+#	the attribute value. When the result is unqualified it
+#	is skipped.
+# .IP "\fB%[SUD1-9]\fR"
+#	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 \fBquery\fR,
+#	and in fact because the input key is known in advance, queries
+#	whose key does not contain all the information specified in
+#	the result template are suppressed and return no results.
+# .RE
+# .IP
+#	For example, using "result_format = smtp:[%s]" allows one
+#	to use a mailHost attribute as the basis of a transport(5)
+#	table. After applying the result format, multiple values
+#	are concatenated as comma separated strings. The expansion_limit
+#	and parameter explained below allows one to restrict the number
+#	of values in the result, which is especially useful for maps that
+#	must return at most one value.
+#
+#	The default value \fB%s\fR specifies that each result value should
+#	be used as is.
+#
+#	This parameter is available with Postfix 2.2 and later.
+#
+#	NOTE: DO NOT put quotes around the result format!
+# .IP "\fBdomain (default: no domain list)\fR"
+#	This is a list of domain names, paths to files, or
+#	dictionaries. 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 MySQL server.
+# .nf
+#	    domain = postfix.org, hash:/etc/postfix/searchdomains
+# .fi
+#
+#	It is best not to use SQL to store the domains eligible
+#	for SQL lookups.
+#
+#	This parameter is available with Postfix 2.2 and later.
+#
+#	NOTE: DO NOT define this parameter for local(8) aliases,
+#	because the input keys are always unqualified.
+# .IP "\fBexpansion_limit (default: 0)\fR"
+#	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.
+# .IP "\fBoption_file\fR"
+#	Read options from the given file instead of the default my.cnf
+#	location. This reads options from the \fB[client]\fR option
+#	group, optionally followed by options from the group given
+#	with \fBoption_group\fR.
+# .sp
+#	This parameter is available with Postfix 2.11 and later.
+# .IP "\fBoption_group (default: Postfix >=3.2: client, <= 3.1: empty)\fR"
+#	Read options from the given group of the mysql options file,
+#	after reading options from the \fB[client]\fR group.
+# .sp
+#	Postfix 3.2 and later read \fB[client]\fR option group
+#	settings by default. To disable this specify no \fBoption_file\fR
+#	and specify "\fBoption_group =\fR" (i.e. an empty value).
+# .sp
+#	Postfix 3.1 and earlier don't read \fB[client]\fR option
+#	group settings unless a non-empty \fBoption_file\fR or
+#	\fBoption_group\fR value are specified. To enable this,
+#	specify, for example, "\fBoption_group = client\fR".
+# .sp
+#	This parameter is available with Postfix 2.11 and later.
+# .IP "\fBrequire_result_set (default: yes)\fR"
+#	If "\fByes\fR", require that every query returns a result
+#	set.  If "\fBno\fR", treat the absence of a result set as
+#	"not found".
+# .sp
+#	This parameter is available with Postfix 3.2 and later.
+# .IP "\fBtls_cert_file\fR"
+#	File containing client's X509 certificate.
+# .sp
+#	This parameter is available with Postfix 2.11 and later.
+# .IP "\fBtls_key_file\fR"
+#	File containing the private key corresponding to \fBtls_cert_file\fR.
+# .sp
+#	This parameter is available with Postfix 2.11 and later.
+# .IP "\fBtls_CAfile\fR"
+#	File containing certificates for all of the X509 Certification
+#	Authorities the client will recognize.  Takes precedence over
+#	\fBtls_CApath\fR.
+# .sp
+#	This parameter is available with Postfix 2.11 and later.
+# .IP "\fBtls_CApath\fR"
+#	Directory containing X509 Certification Authority certificates
+#	in separate individual files.
+# .sp
+#	This parameter is available with Postfix 2.11 and later.
+# .IP "\fBtls_verify_cert (default: no)\fR"
+#	Verify that the server's name matches the common name in the
+#	certificate.
+# .sp
+#	This parameter is available with Postfix 2.11 and later.
+# USING MYSQL STORED PROCEDURES
+# .ad
+# .fi
+#	Postfix 3.2 and later support calling a stored procedure
+#	instead of using a SELECT statement in the query, e.g.
+#
+# .nf
+#	    \fBquery\fR = CALL lookup('%s')
+# .fi
+#
+#	The previously described '%' expansions can be used in the
+#	parameter(s) to the stored procedure.
+#
+#	By default, every stored procedure call must return a result
+#	set, i.e. every code path must execute a SELECT statement
+#	that returns a result set (instead of storing its results
+#	in a table). With "\fBrequire_result_set = no\fR", the
+#	absence of a result set is treated as "not found".
+#
+#	A stored procedure must not return multiple result sets.
+#	That is, there must be no code path that executes multiple
+#	SELECT statements that return a result (instead of storing
+#	their results in a table).
+#
+#	The following is an example of a stored procedure returning
+#	a single result set:
+#
+# .nf
+#	CREATE [DEFINER=`user`@`host`] PROCEDURE
+#	`lookup`(IN `param` VARCHAR(255))
+#	    READS SQL DATA
+#	    SQL SECURITY INVOKER
+#	    BEGIN
+#	        select goto from alias where address=param;
+#	    END
+# .fi
+# OBSOLETE MAIN.CF PARAMETERS
+# .ad
+# .fi
+#	For compatibility with other Postfix lookup tables, MySQL
+#	parameters can also be defined in main.cf.  In order to do that,
+#	specify as MySQL source a name that doesn't begin with a slash
+#	or a dot.  The MySQL 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 the map is
+#	specified as "mysql:\fImysqlname\fR", the parameter "hosts"
+#	would be defined in main.cf as "\fImysqlname\fR_hosts".
+#
+#	Note: with this form, the passwords for the MySQL sources are
+#	written in main.cf, which is normally world-readable.  Support
+#	for this form will be removed in a future Postfix version.
+# OBSOLETE QUERY INTERFACE
+# .ad
+# .fi
+#	This section describes an interface that is deprecated as
+#	of Postfix 2.2. It is replaced by the more general \fBquery\fR
+#	interface described above. If the \fBquery\fR parameter
+#	is defined, the legacy parameters described here ignored.
+#	Please migrate to the new interface as the legacy interface
+#	may be removed in a future release.
+#
+#	The following parameters can be used to fill in a
+#	SELECT template statement of the form:
+#
+# .nf
+#	    SELECT [\fBselect_field\fR]
+#	    FROM [\fBtable\fR]
+#	    WHERE [\fBwhere_field\fR] = '%s'
+#	          [\fBadditional_conditions\fR]
+# .fi
+#
+#	The specifier %s is replaced by the search string, and is
+#	escaped so if it contains single quotes or other odd characters,
+#	it will not cause a parse error, or worse, a security problem.
+# .IP "\fBselect_field\fR"
+#	The SQL "select" parameter. Example:
+# .nf
+#	    \fBselect_field\fR = forw_addr
+# .fi
+# .IP "\fBtable\fR"
+#	The SQL "select .. from" table name. Example:
+# .nf
+#	    \fBtable\fR = mxaliases
+# .fi
+# .IP "\fBwhere_field\fR
+#	The SQL "select .. where" parameter. Example:
+# .nf
+#	    \fBwhere_field\fR = alias
+# .fi
+# .IP "\fBadditional_conditions\fR
+#	Additional conditions to the SQL query. Example:
+# .nf
+#	    \fBadditional_conditions\fR = AND status = 'paid'
+# .fi
