/**

*/

/**
* Composes and optionally sends an email message.
*
* Sending an email works with defining an email template (subject, text and
* possibly email headers) and the replacement values to use in the
* appropriate places in the template. Processed email templates are requested
* from hook_mail() from the module sending the email. Any module can modify
* the composed email message array using hook_mail_alter(). Finally
* drupal_mail_system()->mail() sends the email, which can be reused if the
* exact same composed email is to be sent to multiple recipients.
*
* Finding out what language to send the email with needs some consideration.
* If you send email to a user, her preferred language should be fine, so use
* user_preferred_langcode(). If you send email based on form values filled on
* the page, there are two additional choices if you are not sending the email
* to a user on the site. You can either use the language used to generate the
* page or the site default language. See language_default(). The former is
* good if sending email to the person filling the form, the later is good if
* you send email to an address previously set up (like contact addresses in a
* contact form).
*
* Taking care of always using the proper language is even more important when
* sending emails in a row to multiple users. Hook_mail() abstracts whether
* the mail text comes from an administrator setting or is static in the
* source code. It should also deal with common mail tokens, only receiving
* $params which are unique to the actual email at hand.
*
* An example:
*
* @code
* function example_notify($accounts) {
* foreach ($accounts as $account) {
* $params['account'] = $account;
* // example_mail() will be called based on the first \Drupal::service('plugin.manager.mail')->mail() parameter.
* \Drupal::service('plugin.manager.mail')->mail('example', 'notice', $account->mail, user_preferred_langcode($account), $params);
* }
* }
*
* function example_mail($key, &$message, $params) {
* $data['user'] = $params['account'];
* $options['langcode'] = $message['langcode'];
* user_mail_tokens($variables, $data, $options);
* switch($key) {
* case 'notice':
* // If the recipient can receive such notices by instant-message, do
* // not send by email.
* if (example_im_send($key, $message, $params)) {
* $message['send'] = FALSE;
* break;
* }
* $message['subject'] = t('Notification from !site', $variables, $options);
* $message['body'][] = t("Dear !username\n\nThere is new content available on the site.", $variables, $options);
* break;
* }
* }
* @endcode
*
* Another example, which uses \Drupal::service('plugin.manager.mail')->mail()
* to format a message for sending later:
*
* @code
* $params = array('current_conditions' => $data);
* $to = 'user@example.com';
* $message = \Drupal::service('plugin.manager.mail')->mail('example', 'notice', $to, $langcode, $params, FALSE);
* // Only add to the spool if sending was not canceled.
* if ($message['send']) {
* example_spool_message($message);
* }
* @endcode
*
* @param string $module
* A module name to invoke hook_mail() on. The {$module}_mail() hook will be
* called to complete the $message structure which will already contain
* common defaults.
* @param string $key
* A key to identify the email sent. The final message ID for email altering
* will be {$module}_{$key}.
* @param string $to
* The email address or addresses where the message will be sent to. The
* formatting of this string will be validated with the
* @link http://php.net/manual/filter.filters.validate.php PHP email validation filter. @endlink
* Some examples are:
* - user@example.com
* - user@example.com, anotheruser@example.com
* - User <user@example.com>
* - User <user@example.com>, Another User <anotheruser@example.com>
* @param string $langcode
* Language code to use to compose the email.
* @param array $params
* (optional) Parameters to build the email.
* @param string|null $reply
* Optional email address to be used to answer.
* @param bool $send
* If TRUE, \Drupal::service('plugin.manager.mail')->mail() will call
* drupal_mail_system()->mail() to deliver the message, and store the result
* in $message['result']. Modules implementing hook_mail_alter() may cancel
* sending by setting $message['send'] to FALSE.
*
* @return string
* The $message array structure containing all details of the message. If
* already sent ($send = TRUE), then the 'result' element will contain the
* success indicator of the email, failure being already written to the
* watchdog. (Success means nothing more than the message being accepted at
* php-level, which still doesn't guarantee it to be delivered.)
