  * implementation is the mail plugin whose ID is the value of 'default' key. A
  * more specific match first to key and then to module will be used in
  * preference to the default. To specify a different plugin for all mail sent
  * by one module, set the plugin ID as the value for the key corresponding to
  * the module name. To specify a plugin for a particular message sent by one
  * module, set the plugin ID as the value for the array key that is the
  * message ID, which is "${module}_${key}".
  *
  * For example to debug all mail sent by the user module by logging it to a
  * file, you might set the variable as something like:
  *
  * @code
  * array(
  *   'default' => 'php_mail',
  *   'user' => 'devel_mail_log',
  * );
  * @endcode

  *
  * @code
  * array(
  *   'default' => 'php_mail',
  *   'user' => 'devel_mail_log',
  *   'contact_page_autoreply' => 'null_mail',
  * );
  * @endcode
  *
  * Other possible uses for system include a mail-sending plugin that actually
  * sends (or duplicates) each message to SMS, Twitter, instant message, etc,
  * or a plugin that queues up a large number of messages for more efficient
  * bulk sending or for sending via a remote gateway so as to reduce the load
  * on the local server.
  *
  * @param array $options
  *   An array with the following key/value pairs:
  *   - module: (string) The module name which was used by drupal_mail() to
  *     invoke hook_mail().
  *   - key: (string) A key to identify the email sent. The final message ID
  *     is a string represented as {$module}_{$key}.
