странная сводка журнала Postfix logwatch на моем ubuntu vps [закрыто]

Привет, я был бы очень благодарен, если бы кто-нибудь мог мне помочь с объяснением этого резюме logwatch моей установки postfix на моем ubuntu 10.04 vps. Я действительно не знаю, может ли это быть обычным файлом журнала, из-за множества ошибок аутентификации записей и внешних IP-адресов. Что посоветуете новичку? Спасибо!
