Переадресация в postfix

Всем привет. Пытаюсь победить задачу: есть домен xxx.ru есть внешний ящик yyy@mail.ru есть внутренний пользователь user1@xxx.ru, для которого fetchmail собирает почту с yyy@mail.ru есть внутренний пользователь user2@xxx.ru для которого выполняется пересылка с user1@xxx.ru через /etc/postfix/recipient_bcc_map, содержимое которого: user1@xxx.ru user2@xxx.ru, в main.cfg: recipient_bcc_maps = hash:/etc/postfix/recipient_bcc_map, в postfixadmin заведен сбор с yyy@mail.ru для user1@xxx.ru

fetchmail отрабатывает по крону раз в 5 мин

Засада в том, что почта с yyy@mail.ru доставляется для user2@xxx.ru дважды! А для user1@xxx.ru все ОК!

Где затыка - найти не могу, почему для user2@xxx.ru двойная доставка?

UPD

даже если напрямую отправлять для user1@xxx.ru получаю двойную доставку для user2@xxx.ru

Нид хелп!

UPD 2: нарыл на opennet.ru:

receive_override_options = no_address_mappings без строчки content_filter ДО.

Строку эту добавлял когда, после установки ClamAV, почта >«двоилась». а receive_override_options = no_address_mappings после внешнего контент-фильтра отключает проверку алиасов и bcc..

Проверил - работает, будем тестить. Спасибо всем, кто откликнулся за помощь и особенно @mky за наводку!!!

  1. Посмотрел - 1 к 1
  2. Не смог в bcc сделать пересылку на две учетки, при пересылке они воспринимаются как 1 адрес, сделал алиас и в него впихнул две учетки, как результат: письма валятся каждому пользователю из алиаса дважды.
  3. ну вот к сожалению не ок.
