服务器正在侦听端口10023,但我注意到它只是通过IPv6监听：
> sudo netstat -a | grep 10023 tcp6 0 0 ip6-localhost:10023 [::]:* LISTEN
我没有防火墙规则可以否认特定的端口,地狱,我继续并刷新规则集只是为了确认它.这是我的postconf -n的输出(我编辑了我的域名代替“mydomain.com”：

正如您所看到的,我甚至试图通过inet_protocols指定它侦听ipv4连接.我已经尝试过,有没有这个命令.
任何有关故障排除的帮助将不胜感激！当然,如果你看到我的配置中的任何内容显然是愚蠢的,那么我不会高于建议或批评.
解决方法
smtpd_recipient_restrictions = ...,permit
如果从smtpd_recipient_restrictions中删除check_policy_service inet：127.0.0.1：10023,则应该消除该错误,但您仍应确定将在此处运行的postgrey或其他服务发生了什么.
在Unbuntu系统上检查Postgrey
通常,postgrey默认配置将在端口10023上侦听连接,并确定是允许还是拒绝它们. Unbutu服务器上的一些可以检查以确定是否安装的服务器是……
>你有/ etc / default / postgrey文件吗？这是基本的配置文件.
>你有/ etc / postgrey文件夹吗？这是您可以将元素列入白名单的地方.
>当你运行>哪个postgrey会找到二进制文件？我可以在/usr/sbin / postgrey中找到.
>你有一个/etc/init.d/postgrey脚本在启动时启动吗？这是Ubuntu守护进程的典型位置.
这些只会给你一些关于这个服务器是否曾经一次配置过postgrey的线索.如果进程在服务器上运行不正常,则需要进一步查看故障排除.
