我正在尝试使用 Postfix 和 Dovecot 设置邮件服务器，使用 MySQL 来存储别名、域和用户。
问题是用户没有收到电子邮件。
根据日志文件，收到的邮件被保存了，但结果是没有存储。
但无论如何都会发生一些事情，因为创建了一个文件夹 /mail，其中有一个 .imap，其中有另一个文件夹 /INBOX，其中包含以下文件：
- dovecot.index.cache
- dovecot.index.log

日志中没有任何错误或警告可能表明 vmail 用户无权访问或找不到路径，所以我有点沮丧。
我尝试在本地交换邮件，发送本身也可以。此外，还可以发送到外部的我的 gmail 地址。
除此之外，我再次检查了我的配置，但不幸的是找不到任何能让我解决问题的东西。
