我已经安装并配置了 postfix，但是当我测试 telnet 时
我得到了结果
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
我尝试使用更多方法来解决问题，但找不到解决方案。
这

首先，您应该检查 postfix 进程是否正在运行：
ps axu | grep master
其次，检查正在监听 25 端口的内容：
netstat -apn | grep :25
你应该得到类似的输出：
tcp 0 0 0.0.0.0:25 0.0.0.0:* 侦听 5690/主控
第三，检查 postfix 配置：
postconf | grep smtp_bind_address
它应该是空的，例如 postfix 监听所有地址：
smtp_bind_address = smtp_bind_address6 =
