尝试使用this文章配置Exim邮件服务器。我可以在我的本地网络中使用这个服务器，但是当我尝试从互联网上使用它时，我会犯一些错误。端口10000-20000转换到服务器机器。我在CentOS 7的Docker镜像中所做的一切。也有CentOS 7的主机。Docker + Exim + Dovecot。不允许继电器
缩写：
- test_domain.tk - 我的测试域
- 为test1，test2的 - 测试用户
- [email protected] - 测试外部电子邮件
- 123.456.789.876 - 我外部IP（我有路由器与NAT）
- 10.0.7.30 - 码头的隧道
码头工人开始用命令：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

当我尝试从互联网连接时，邮件客户端中出现超时错误，并且在Exim中出现空日志。这可能是与路由器工作的问题。如何使它工作？
问我是否需要更多数据。提前致谢。
它实际上是相反的，OP在主机上将端口10025映射到容器中的25个。 – 2015-02-14 03:00:13
如果是这样的话，它永远无法工作。外部没有任何东西会知道要传送到端口10025，而不是端口25，这是默认的SMTP端口。必须做的第一件事是修复他的容器端口映射，以便外部的25映射到内部正在监听的任何exim。 – 2015-02-16 13:54:59
