Здравствуйте!!! Помогите пожалуйста исправить ошибку в коде!
Ошибка такова: При регистрации или смене пароля приходит письмо на е-маил, с соответствующим названием письма, то есть все верно определяется какое письмо должно прийти, НоО ни в одном письме нет тела, то есть приходит пустое письмо
Вот код класса:

<?php
/**
 *           Класс для работы с почтой
 */
if( ! defined( 'LM' ) ) die('Попытка взлома?');
 
class mail {
  var $errstr;
  var $headers;
  var $textbody;
  var $htmlbody;
  var $attachments;
  var $boundary;

  function mail() {

а вот само тело письма, которое должна отправляться:

 $htmltext = 'Для завершения регистрации на сервисе '.$_SERVER['HTTP_HOST'].'

     $htmltext = $htmltext . '<br><br>';
     $htmltext = $htmltext . 'С уважением,<br>Администрация сайта <b><a href="http://'.$_SERVER['HTTP_HOST'].'/">'.$_SERVER['HTTP_HOST'].'</a></b>';

     $main->mail->set_header('From', $conf['support_mail']);
     $main->mail->htmltext($htmltext);
