####空壳邮件####

空壳:

 别人看见的是这台“假主机”,炮灰。

 对外显示与真实机相同,别人发送的邮件表象给它,实则是它转给真是主机。

1.[root@mail ~]# vim /etc/postfix/main.cf  

 

 76 myhostname = qq-mail.qq.com    #主机名

 83 mydomain = qq.com    #域名

 99 myorigin = westos.com    #真实服务器所在的域

 116 inet_interfaces = all

 119 inet_protocols = all

 164 mydestination =    #不接受任何邮件

 316 relayhost = 172.25.254.113    #转发到真实的邮件服务器
