Проблема с postfix

[Kovit]

Имеется web сервер с апачей.
Установлен там logwatch и с недавнего времени при посылке отчета на мейл выдается следующая ошибка
Я так понимаю мэйл серверу не нравится HELO .  Подскажите куда копать?

mailname какое стоит?

[Kovit]

www.xxxx.yy вот такой стоит.
Причем перестал слать очень резко.
В чем дело смотреть майл сервер или на этой машине ?

может надо смотреть не mailname, а myhostname?
