всем привет, люди подскажите, настроен постфикс+амависд+кламав, все работает отправляет принимает письма, но если в письме запросить уведомление о прочтении или доставки, то после доставки письма, у получателя при открытии письма не вылазит запроса, об отправке уведомления, и соответсвенно обратно отправителю ничего не приходит... пробовал отключать контент-фильтр, и убирал smtpd_*_restrictions, не помогло... подкажите как мне включить эту функцию?

ps.версии пакетов все свежие, постфикс поддерживает dsn
