postfix/dovecot 说“没有给出 postmaster_address 设置”，但它是

Question

我正在尝试将 postfix 和 dovecot 配置为与存储在 MySQL 中的虚拟域一起工作，但是每当邮件从 postfix 传递到 dovecot 时，我都会遇到这个问题。

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. )

现在，因为我知道 Google 是如何工作的，所以我发现了很多关于“您需要将 postmaster_address 选项添加到 15-lda.conf 中的 lda 协议行”的参考资料。

是的，这里是输出 doveconf -n

我的/etc/postfix/master.cf包含它以将它连接到 dovecot

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

我还能检查什么以查看导致此错误的原因？

Answer 1

我修复了它，但修复不是那么明显。

缺少 postmaster_address 设置并不是真正的问题。dovecot-lda 没有查看正确的配置文件是实际问题。

然而，更深层次的问题似乎是我在 Google https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/671065上随机遇到的这个“功能” ，其中

的deliver配置（LDA）被存储在“/etc/dovecot/conf.d/01-mail-stack-delivery.conf”。这从根本上被破坏了，因为 dovecotdeliver忽略了包含在 !include_try 和 !include 中的文件。此问题显示此错误：

Fatal: postmaster_address setting not given

并且通过添加-c /etc/dovecot/conf.d/01-mail-stack-delivery.conf到master.cf 中的 dovecot-lda 命令行来治愈（尽管您必须使 conf.d 和文件本身都具有世界可读性，以便非根 dovecot-lda 可以读取它，这感觉就像可怕的黑客，而不是实际的解决方案......但现在我有工作邮件。

我把这个答案留在这里，以防有其他人在使用 Ubuntu 时遇到这种情况。愿你花的时间比我修复它的时间少。
