我的 Postfix 设置不会接收来自本地主机（sendmail）以外任何地方的电子邮件。
我可以从我的服务器登录并发送电子邮件，但没有任何消息发送。
这是我的 postconf -n

这是日志中的错误

有什么建议吗？
答案1
这种行为是由以下线条创建的
smtpd_sender_restrictions = permit_sasl_authenticated, permit_mynetworks, reject
和
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
不要（重复不）直接删除reject！
我建议不要运行任何可公开访问的邮件服务器，除非您已经拥有管理这些庞然大物的经验。在您的网络中运行它，使用小型虚拟化结构来感受陷阱，然后读。
