Exim4 Rejected RCPT: Unrouteable address when using data lookup
我正在嘗試將最初發送到 的電子郵件重定向
hello@example.com到mrxxx@example.com.我有
aliases文件：hello: mrxxx@example.com以及以下路由器：
local_router: driver = accept domains = +local_domains local_parts = mrxxx transport = local_dst cannot_route_message = Unknown mailbox no_more aliases_router: driver = redirect data = ${lookup{$local_part}lsearch{/etc/aliases}} cannot_route_message = Unknown mailbox allow_defer allow_fail no_more
local_dst運輸如下所示：local_dst: driver = appendfile directory = /var/mail/$local_part/Maildir delivery_date_add envelope_to_add return_path_add maildir_format mode_fail_narrower = false根據調試資訊，它應該可以正常工作：

我的正確設置
aliases_router結果如下（幾乎是來自 Exim docs的複制/粘貼）：aliases_router: driver = redirect data = ${lookup{$local_part}lsearch{/etc/aliases}} cannot_route_message = Unknown mailbox我不確定為什麼
no_more和no_verify（如評論中所述）在這裡出現了流氓設置。allow_defer並且allow_fail似乎沒有阻止任何東西，因為它們僅用於啟用 Exim 過濾器中的某些功能。如果您有關於
no_more和no_verify設置的解釋，請發表評論或發布答案，我很樂意接受。
