【问题描述】：
尝试使用this 文章配置 Exim 邮件服务器。我可以在本地网络中使用此服务器，但是当我尝试从 Internet 使用它时，我遇到了一些错误。端口 10000-20000 转换为服务器机器。我在 CentOS 7 的 docker 映像中所做的一切。主机也使用 CentOS 7。
缩写：
- test_domain.tk - 我的测试域
- test1、test2 - 测试用户
- test@external.com - 测试外部电子邮件
- 123.456.789.876 - 我的外部 IP（我有带 NAT 的路由器）
- 10.0.7.30 - 码头隧道
使用命令启动 docker： docker run -d --name mail -h test_domain.tk -p 10025:25 -p 10587:587 -p 10465:465 -p 10143:143 -p 10993:993 mail/server:localwork start_server

当我尝试从 Internet 连接时，邮件客户端出现超时错误，并且 Exim 中的日志为空。应该是路由器工作的问题。如何让它发挥作用？
询问我是否需要更多数据。提前致谢。
