[App] Postfix 配置本地邮件服务

配置本地邮件服务需求：

这些系统不接受外部发送来的邮件；

本地发送的任何邮件都会自动路由到 mail.group8.example.com；

在这些系统上发送的邮件显示来自于 server.group8.example.com；

192.168.1.151

 [root@system1 ~]# postconf -e"inet_interfaces = loopback-only"                                      #修改配置文件，邮件只本地接受

[root@system1 ~]# postconf -e "mydestination = "                                                                #发送出去邮件的其他目的地都为空

[root@system1 ~]# postconf -e "local_transport = error: localonly"                                   #只本地传输，并定义报错信息

[root@system1 ~]# postconf -e "relayhost =[mail.group8.example.com]"                        #本地发送的邮件自动路由到mail,group8.example.com

[root@system1 ~]# postconf -e "myorigin =server.group8.example.com"                        #设置显示的邮件来源

[root@system1 ~]# systemctl restart postfix                                                                           #重新启动邮件服务

[root@system1 ~]# echo "hello" | mail -s "hellosystem1" dave                                           #发送测试邮件，邮件标题是hello system1，内容是hello,发送给本地用户dave

[root@system1 ~]# curlhttp://server.group8.example.com/pub/received_mail/8         #查看邮件，完成之后记得在system2上做相同配置
