Отшиваются письма активации

[Jack]

PHPBB последний, активация - пользователем, с/без использования smtp для отправки - всё равно. Не нравятся мне заголовки писем - поле Return-Path пустое почему-то, если применяю mod с этого сайта, который в email.php к mail() добавляет -f{адрес системы}, то это прямо в заголовке письма отражается как warning authentification - адрес изменён ключом -f. А письма заворачиваются с заголовками:
