Smtp ошибка 451 невозможно добавить получателя temporary lookup failure

I am trying to set up postfix, but I get a «Temporary lookup failure» error

main.cf:

mydomain = dzervas.gr
myorigin = dzervas.gr

mydestination = localhost, localhost.$mydomain, $myhostname, $mydomain, mail.$mydomain, www.$mydomain

I should point out that I haven’t set up the DNS records yet (dzervas.gr is not pointing my new server yet)
Also I’m on arch linux x86_64

EDIT: I created an empty /etc/aliases and then newaliases
new problem (in telnet):

rcpt to: dzervas@dzervas.gr
550 5.1.1 <dzervas@dzervas.gr>: Recipient address rejected: User unknown in local recipient table

but!:

rcpt to: root@localhost
250 2.1.5 Ok
data
354 End data with <CR><LF>.<CR><LF>
hhahahahha
.
250 2.0.0 Ok: queued as <some-code>

EDIT 2: solved the Recipient address rejected: User unknown in local recipient table by setting local_recipient_maps = in main.cf
However, now my mail to dzervas@dzervas.gr get queued! it does not go at /var/mail/vmail/dzervas.gr/dzervas/ as it should!

но принимать отказывается
на английкой теме форума активное обсуждение: viewtopic.php?t=19994
на первой странице пишут что помогает откат на раннюю версию, дальше пока не читал

откатывать версию нет необходимости
там люди разобрались и на последней странцие конфмг exim-а с исправлениями выложили
я за пару минут все исправления с помощью Notepad++ с плагином compare внёс в свой конфиг, рестартанул эксима и почта пошла в обе стороны

делов реально на 5 минут с перекурами

Выложить-то выложили, да удалили. Не сохранилось правок?

Попробуйте в вебархиве поискать — может, сохранились снапшоты.

Please paste related postfix log in /var/log/maillog, not just log of roundcube.

Re: [SOLVED] SMTP Error: SMTP error(451): Failed to add recipient

It seems there is some issue with iRedAPD. I have gone through the documents and didnt find any files for iRedAPD in iRedOS.
is it not included with iRedOS?

iRedAPD service is not running.
Please start it immediately:

# /etc/init.d/iredapd restart

It will log in file /var/log/iredapd.log, If it doesn’t work, please check its log file first.

Re: [SOLVED] SMTP Error: SMTP error(451): Failed to add recipient

*) If ‘postfix-pgsql’ package is installed, did you restart Postfix service?
*) What’s the latest error message now?

Установлен iredadmin (postfix + roundcube)

Неожиданно вдруг стали появляться следующие ошибки.
При попытке отправить письмо в Roundcube может вылезти такая ошибка:
1. SMTP ошибка (451): Невозможно добавить получателя «user@yandex.ru» (4.3.0 <mymail@mydomain>: Temporary lookup failure)
либо эта вместо нее может быть
2. SMTP ошибка: [451] 4.3.0 Error: queue file write error

Но если долго тыкать кнопку отправить, то письмо в итоге уйдет.

При просмотре лога по первой ошибке видно такое:
Jan 11 18:35:53 postfix/smtpd[5071]: warning: hostname mydomain does not resolve to address server-ip
Jan 11 18:35:53 postfix/smtpd[5071]: connect from unknown[server-ip]

При второй ошибке видим в логе это:

Подумал на mysql, выставил там лимит в 500 подключений. По процесс листу столько далеко и нет.
Но ошибки продолжаются. Вначале письмо отсылалось при 3-4 попытках, теперь попыток может быть более десятка и потом только письмо уйдет. Где-то что-то забивается? Подскажите куда копать.

Добрый день. Имеется Centos 6.2, а на нем Postfix-2.6.6. Работал полгода без проблем.Проблема в следующем вот уже несколько дней появляется прихожу утром и вижу в логах следующее:

При этом лог разрастается до вселенских размеров. При этом в 23:00 запускается awstats для парсинга и отжирает все ресурсы, все начинат дико тормозить.
Так как думал что спам атака то в первый день закрыл этот ip 85.17.138.134 в iptables. И добавил ограничения на соединения в main.cf

anvil_rate_time_unit=60s
smtpd_client_connection_rate_limit=20
smtpd_client_connection_count_limit=3
smtpd_connection_message_rate_limit=10

И внес в проверку заголовков header_checks=pcre:/etc/… след строку /From:.*<[?]+([^>]+)/ REJECT In your email adress wrong symbols Для отсеивания адресов вида ????@.

Но сегодня ситуация опять повторилась но в логе уже был другой ip и сервак

Тогда прслушал tcpdumpom все интерфейсы никаких соединений на smtp порт не было. Но ошибки продолжали сыпаться. Затем обрубил 25 порт на инетовском и локальном интерфейсе — ошибки все равно продолжали валиться. Посмотрел qshape — все очереди пусты, да и в логах пишет что NOQUEUE.
Только после перезапуска postfix ошибки перестали валиться.

Очень прошу помогите, в чем может быть причина.
