postfix/dovecot 說“沒有給出 postmaster_address 設置”，但它是

我正在嘗試將 postfix 和 dovecot 配置為與儲存在 MySQL 中的虛擬域一起工作，但是每當郵件從 postfix 傳遞到 dovecot 時，我都會遇到這種情況。

Apr 26 11:54:40 smtp postfix/pipe[13165]: 20CCE1C30D5: to=<james@domain.ext>, relay=dovecot, delay=45846, delays=45846/0.28/0/0.14, dsn=4.3.0, status=deferred (temporary failure. Command output: lda: Error: user james@domain.ext: Error reading configuration: Invalid settings: postmaster_address setting not given lda: Fatal: Internal error occurred. Refer to server log for more information. )

現在，因為我確實知道 Google 的工作原理，所以我發現很多關於“您需要將 postmaster_address 選項添加到 15-lda.conf 中的 lda 協議行”的參考資料。

是的，這是輸出doveconf -n

我的*/etc/postfix/master.cf*包含這個以將其連接到 dovecot

dovecot      unix   -        n      n       -       -   pipe
       flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/dovecot-lda -d $(recipient)

我還能檢查什麼以查看導致此錯誤的原因？

我修復了它，但修復不是那麼明顯。

缺少 postmaster_address 設置並不是真正的問題。dovecot-lda 沒有查看正確的配置文件是實際問題。

然而，更深層次的問題似乎是我在 Google https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/671065上隨機遇到的這個“功能”

deliver配置 (LDA) 儲存在“/etc/dovecot/conf.d/01-mail-stack-delivery.conf”中。這從根本上被破壞了，因為 dovecotdeliver忽略了包含在 !include_try 和 !include 中的文件。此問題顯示此錯誤：

Fatal: postmaster_address setting not given

並通過添加-c /etc/dovecot/conf.d/01-mail-stack-delivery.conf到master.cf中的 dovecot-lda 命令行來解決（儘管您必須使 conf.d 和文件本身都是世界可讀的，以便非 root 的 dovecot-lda 可以讀取它，這感覺就像可怕的黑客，而不是實際的解決方案……但現在我有工作郵件。

我把這個答案留在這裡，以防有其他人在使用 Ubuntu 時遇到這種情況。願你花的時間比我修復它的時間少。
