Postfix

[Sector9]

    Привет ребя! У меня такая проблема. Стоит Ubuntu 7.10. поднят почтовик postfix. Все нормально работало до вчерашнего утра. А сейчас не доходят письмя до внешних серверов, хотя на внутренние ящики письма нормально ходят.
Проверял ip в блеклистах. Не числится.
Пробывал коннектица телнетом по 25 порту на сервера майл, рамблек.. Не коннект по таймауту.
В логах такие ошибки:

может дело в этом -  Client host rejected: cannot find your hostname ...
