###空壳邮件####

服务端：116

空壳邮件客户端：128

配置128空壳：

vim /etc/postfix/main.cf
  75 myhostname = nullmail.example.com
  83 mydomain = example.com
  99 myorigin = qq.com       ##和服务端的域名必须一致
  113 inet_interfaces = all
  164 mydestination =
  316 relayhost = 172.25.254.116    ##为服务端ip

systemctl restart postfix

用空壳客户端给自己本机发送邮件

mail root

实际接受到邮件的为服务端空壳未接收到邮件
