Всем привет. Имеется связка Debian lenny beta2 + exim 4.69-5 + dovecot. Без БД. С dovecot'ом проблем не наблюдается. С Exim'ом пытаюсь разобраться уже третьи сутки безуспешно по следующей проблеме: стойкое ощущение, что Exim на моём сервере релеит почту от левых доменов на левые домены. Вывод сделан на основании записей в mainlog'е чуть ниже. Для части левых сообщений как я понимаю срабатывает "domainlist relay_to_domains = 'fzfx.ru'", для части, увы, нет; обратите внимание на строки с "Message accepted for delivery", которые меня и беспокоят - домены, которые фигурируют там я не разрешал.

Увы, почтовым сервером занимаюсь впервые. На выходных вообще сделал глупость - не погасил после экспериментов exim и буквально за сутки им попользовалось очень много народу в своих целях. ( Суточные логи весили по 200 метров... Сейчас ситуация намного более радостная - на половину сообщений с левых доменов на левые домены exim отвечает "relay not permitted". Но на другую половину подобных мессаг - другие ответы, в т. ч. и (ужас!) приёмы и доставки этих сообщений.
Воскуривание мануалов мне помогает увы слабо, ибо топчусь вокруг одних и тех же параметров в конфиге, касающихся relay_to и иже с ним, а результата лучшего чем того что привожу добиться не удалось.
Привожу малую часть конфига, боюсь что за весь запинаете. Огромная к вам просьба - подтолкните, задайте наводящие вопросы, запросите результаты команд для exim'а в шелле, направьте на альтернативный мануал (желательно русскоязычный), отличный от того что на exim.org... Если можно сюда положить весь конфиг - сообщите, выложу; весит 21 КБ, но я могу его пропарсить вручную, убрав явно лишнее, могу отсечь те части, на которые укажете вы. Вообще же конфиг (autogenerated.conf) - почти дефолтный из пакета exim4 для debian с минимальными изменениями. Заранее спасибо.
