使用Dovecot、MySQL和SpamAssasin的后缀配置

Question

我对Debian比较熟悉，一直试图用这个教程安装邮件服务器。

现在，我已经浏览了网站上提供的所有评论，试图解决问题，但它们似乎不起作用。我在服务器故障上遇到了一些类似的问题，但它们也不起作用。我最大的挑战是真实地制作堆栈跟踪的正面或反面。

我看到了很多警告和一些错误，我不知道路线的原因是什么。最大的挑战是，这是我第一次处理与邮件相关的/smtp。

我解决的第一个错误是

Fatal: Error reading configuration: Invalid settings: postmaster_address setting not given

通过将"postmaster_address = postmaster@example.com"添加到文件/etc/dovecot/conf.d/15-lda.conf。

备注

基于多个帖子，将此行添加到的文件会发生变化。

现在来了我搞不懂的长长的堆栈跟踪

Answer 1

看起来/etc/ssl/certs/dovecot.pem存在问题，检查文件是否存在，Dovecot有读取它的权限，或者禁用SSL功能。

在我的Ubuntu机器上，dovecot.pem在/etc/dovecot中，有用户根和组dovecot。

Answer 2

Dovecot包通常提供一个包装脚本/usr/share/doc/dovecot-<version>/mkcert.sh。尝试生成自签名证书。
