Ситуация такая - работает себе почтовый сервер. Почту отправляет postfix. Сегодня надо было мне отправить почту начальству. Ничто не предвещало беды :) Нажимаю я Отправить в почтовике, а мне в ответ:
Sending of message failed. The message could not be send... в общем время ожидания истекло.
Contact your network administrator.
Хм, думаю. А почему? Смотрю логи и вот что-то ничего понять не могу. Четыре строчки.

postfix/smtpd[10830]: warning: 188.162.166.122: hostname wimax-client.yota.ru verification failed: hostname nor servname provided, or not known
postfix/smtpd[10830]: connect from unknown[188.162.166.122]
postfix/smtpd[10830]: lost connection after UNKNOWN from unknown[188.162.166.122]
postfix/smtpd[10830]: disconnect from unknown[188.162.166.122]

Меня очень смущает третья строчка, что такое after UNKNOWN?
И почему он меня пускать не хочет?
