Идите и читайте... Google в помощь

А вопрос не совсем понятен --- "любое письмо типа lamo@xxx.ua duren@xxx.ua" домен xxx.ua ваш и пользователя lamo нет на вашем сервере? Или postfix должне проверять адрес lamo@xxx.ua в ходе приема письма?

Таких пользователей нету, нужно чтобы он давал обратку что пшел нафиг, такого e-mail адреса нету :)

так по дефолту Postfix и отшивает! -
