我在CentOS上设置邮件服务器时遇到了一些麻烦，截至目前，根本没有发送任何东西，我也不完全确定为什么，我试了一些指南，但没有一个似乎解释任何东西关于这个问题，我不知道我是否可能在某处input了错误。
我不完全确定什么configuration我需要在这里发布，但如果你需要他们，只要问:)
我使用的服务器是托pipe在我家的CentOS服务器，我们已经设置它从端口1到65556从路由器接收端口，所以所有端口都可用于服务器，应该没有这方面的麻烦。
这是本地用户错误日志：
在/ var /日志/ maillog的：

新的Postconf -n设置：

正如我从日志中看到的，您尝试从不存在的域发送邮件。 我假设你使用的是localhost或localhost.localdomain。 您应该使用fqdn
将以下行添加到main.cf并重新启动postfix
myhostname = mail.example.net mydomain = example.net myorigin = $mydomain
PS你应该用你的真实域名replaceexample.net
