Поставил exim особо с настройками не крутил (тока авторизация). Проблема следующая: шлю почту на @yandex.ru  все уходит-приходит без проблем. Но, например, при попытке отправить на домен @mail.ru сразу отскакивает с ошибкой.

Вот отлуп:

а вы не писали на емайл ? который вам указали

как я понял ваш почтарь использует винамический адрес а с него они почту не принимают.
вот и вся беда.

писал -- там молчат... А адрес 100% статический. Да и как они могут узнать динамический или нет у меня адрес?

>писал -- там молчат... А адрес 100% статический. Да и как они
>могут узнать динамический или нет у меня адрес?

интуитивно и/или по базе RIPE.  пишите им еще, другого варианта нет.

>писал -- там молчат... А адрес 100% статический. Да и как они
>могут узнать динамический или нет у меня адрес?

Могут из днс имени, особенно если в нем содержится что-то вроде *dialup* *ppp* итд по такому принципу.

А мне кажется, что текст ошибки любой может быть. Причина важна!

Попросил провайдера сменить PTR запись на mail.guns.ru (раньше в имени действительно была подстрока "ppp"). На @mail.ru как потом оказалось попал в черный список (видимо как раз из-за PTR записи, т.к. как только запись сменили сразу отправил письмо на @mail.ru и ошибка уже была другой, а именно наличие моего адреса в блек-листах). Списался с саппортом -- меня разбанили, все хорошо, но!.. На некоторые домены почта не ходит по-прежнему. В логах хилая такая информация:

=======================

userX@tatal.ru R=dnslookup T=remote_smtp defer (-1): smtp transport process returned non-zero status 0x0200: exit code 2

userX@52hunter.ru R=dnslookup T=remote_smtp defer (-1): smtp transport process returned non-zero status 0x0200: exit code 2

userX@oxota.kirov.ru R=dnslookup T=remote_smtp defer (-1): smtp transport process returned non-zero status 0x0200: exit code 2

=======================

С чем это может быть связано?.. (На все публичные шары почта просто улетает)

это вгугл чистой воды :)

при попытке разморозить сообщение вываливалась ошибка:

Fatal: no entropy gathering module detected

сделал chmod o+r /dev/urandom /dev/random после чего все замороженные сообщения отправились и никаких ошибок с доставкой больше не появлялось.

Всё просто:
У тебя неправильно настроены MX записи.
Получается, что ты шлёшь почту с внутреннего ипа сервера, а принять пытаешься по внешнему.
Некоторые почтари сравнивают их и режут, мотивируя динамическим ипом. (ака спам)
Чтобы работало всё, MX должен быть настроен следующим образом:
Запись типа A - указывает на ип твоей внешней днс зоны
Запись типа A - указывает на сервак под ипом твоей внешней ДНС зоны
Запись типа MX - указывает на запись типа А твоей внешней днс зоны (Т.Е. НА ПЕРВУЮ ЗАПИСЬ ТИПА А, а НИХРЕНА НЕ НА ВТОРУЮ!!)

Есть, правда, и другие варианты:
- твой ип действительно динамический
- ты используешь сервер ретрансляции, который настроен никуя неправильно, либо использует динамические ипы.

Удачи :)

Ага, вот :)
>host mxs.mail.ru [194.67.23.20]
>Return-path: <vasya-gaykin@guns.ru>
>Received: from [192.168.2.1]

Судя по этим строчкам, причина всё-таки первая.
Видишь, мэйлру видит твоё сообщение, как от (from) [192.168.2.1],
а пингуя твой днс - получает host mxs.mail.ru [194.67.23.20]
Вот и вся наука :)
