Добрый день!

ОС: Fedora Core 5, почтовый сервер: Exim 4.62/4.69 (первый ставился yum'ом, второй собирал из исходников - проблема сохраняется).

В /etc/aliases есть запись  типа

userlist:    userlist,user1

где userlist и user1 - локальные учётные записи.

Проблема: при отправлении почты на

userlist@example.com

сообщение *дважды* доставляется всем, кто перечислен, кроме userlist (в данном случае - user1), и один раз, как и ожидается, userlist.

Привожу данные, которые могут помочь разобраться:

Никакая комбинация параметров check_ancestor и repeat_use в system_aliases не решает проблему.

Может ли кто-нибудь помочь разобраться, как побороть двойную доставку сообщений?

Спасибо.

Спасибо, но дело не в этом. Проблема звучит так: если есть транспорт типа DPAM'овского, типа pipe, то сообщение "разветвляется", каждая запись из To/Cc обрабатывается отдельно, а потом передаётся последующим рутерам. В итоге получаем множественные копии.

Не очень понимаю, что с этим делать.
