+ * 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
