我没有问题发送电子邮件，我的EC2服务器，但我怎么能检查发送到我的邮箱？我有一个弹性IP设置和修改反向DNS记录。我是否需要安装Postfix的接收电子邮件？

I have no trouble sending out email with my EC2 server, but how can I check the email that is sent to me? I have an elastic IP setup and modified reverse DNS records. Do I need to install Postfix to receive email?

推荐答案

我该做的是测试如果你可以打开一个telnet连接到端口25的服务器上的第一件事情。那么你知道什么是监听传入的邮件。

I suppose the first thing to do is testing if you can open a telnet connection to port 25 on your server. Then you know if anything is listening for incoming mail.

如果没有，那么你或许应该安装后缀以及测试你的防火墙设置（我似乎记得有某种形式的防火墙设置哪些端口，允许在Web界面的EC2）

If not, then you should probably install postfix as well as test your firewall settings (I seem to recall the EC2 having some sort of firewall setting for which ports to allow in the web interface)
