Здравствуйте. надеюсь поможете.
установил asp9.2 и postfix 2.0.16 (он автоматически ставится в chroot).
настроил внутренний днс.
проблема в следующем : не могу добится работы постфикса в chroot с rejecting mail from unknown local users.
если ecnfyjdbnm local_recipient_maps =  , то почта доставвляется номально между локальными пользователями, а если я хочу включить проверку -  local_recipient_maps = proxy:unix:passwd.byname $alias_maps
то в maillog ошибка -
