我试图configurationpostfix和dovecot与存储在MySQL中的虚拟域一起工作，但是当邮件从postfix传递到dovecot的时候，我一直在遇到这个问题。
Apr 26 11:54:40 smtp postfix/pipe[13165]: 20CCE1C30D5: to=<[email protected]>, relay=dovecot, delay=45846, delays=45846/0.28/0/0.14, dsn=4.3.0, status=deferred (temporary failure. Command output: lda: Error: user [email protected]: 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，所以我发现了很多参考资料：“你需要在15-lda.conf中添加postmaster_address选项到lda协议行。
这是doveconf -n的输出

我的/etc/postfix/master.cf包含这个连接到dovecot
dovecot unix - nn - - pipe flags=DRhu user=vmail:vmail argv=/usr/lib/dovecot/dovecot-lda -d $(recipient)
我还能检查什么导致这个错误？
我修好了，但是修复并不是那么明显。
有一个失踪的postmaster_address设置不是实际的问题。 dovecot-lda不看正确的configuration文件是真正的问题 。
然而，更深层次的问题似乎是我随机在Google上发现的“function” https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/671065
deliverconfiguration（LDA）存储在'/etc/dovecot/conf.d/01-mail-stack-delivery.conf'中。 由于dovecot的deliver忽略了include_try和！include中包含的文件，所以这个问题基本上被破坏了。 这个问题显示了这个错误：Fatal: postmaster_address setting not given
并通过添加-c /etc/dovecot/conf.d/01-mail-stack-delivery.conf到master.cf中的dovecot-lda命令行来解决（虽然然后您必须使conf.d和文件本身是世界可读的，所以非根dovecot-lda可以读取它，这感觉像一个可怕的黑客，而不是一个实际的解决scheme…但现在我有工作邮件。
我在这里留下这个答案，以防有其他人在这种情况下使用Ubuntu。 你可以花更less的时间比我修理它。
对我来说更好的答案是补充
postmaster_address=postmaster at DOMAIN
显然在你的域名中replace你的域名为“域名”
/etc/dovecot/dovecot.conf
然后重新启动dovecot
service dovecot restart
不是我的答案…我只是在这里find它： https : //github.com/mail-in-a-box/mailinabox/issues/31 ，它解决了我的问题。
