我已经安装了 elastix 3 稳定版 (postfix, cyrus sasl2)。我将其用作本地网络中的电子邮件服务器。这里一切运行如下：
- 从本地向本地发送电子邮件 =好的！
- 从本地向外部发送电子邮件 =好的！
- 接收电子邮件（从本地发送）=好的！
- 接收电子邮件（发送从外部) =不！ ***
事实上，唯一的问题是我无法在收件箱中收到从外部发送的电子邮件，但是我已经可以在收件箱中收到从本地网络发送的邮件。我担心这个问题出了什么问题。但如果有人能帮助我解决这个问题，我将不胜感激。master.cf 和 main.cf 文件也如下所示，我不知道我是否应该进行任何其他配置。还请注意看来我的 ISP 阻止了端口 25，所以我使用另一个端口作为 smtp。

答案1
我找到了答案。问题实际上与邮件服务器无关。似乎是端口 25 应该开放为了接收外部邮件。没有这个，它就不起作用。我已经在其他论坛上看到过一些关于它的内容，但我无法想象它有多重要。一旦它被解封，外部电子邮件就会收到。我只想分享我的解决方案和我得到的答案。:)
