我在 Amazon EC2 实例上安装了 Cenos 6。我还安装了 exim+dovecot 来发送和接收电子邮件。我有两个域和两个带有连接弹性 IP 的网络接口。示例中的内部 IP 为：
172.31.108.135
172.31.110.53
以及两个域：
domain1.com
domain2.com
我使用手册和示例 (+DKIM、PTR 等) 配置了 exim。发送工作正常。但我的邮箱无法接收电子邮件。
我的 /etc/exim/ 文件夹文件：

黑名单 空的文件
域名列表 空的文件

我不是 Exim 专家，但您的 local_delivery 传输正在从密码文件中提取第 4 个字段，并且看起来文件名是第 5 个字段。
