二 空壳邮件

1 ）null客户端

1 vim /etc/postfix/main.cf

mydomain = example.com###域名###

myorigin = westos.com###伪装为真实邮件服务器的所在域###

myhostname = mail.example.com###主机名###

mydestination =###为空，不接受邮件###

relayhost = 172.25.254.112###转发给真实的邮件服务器###

2 systemctl restart postfix.service

3 测试：

空壳邮件服务器：

[root@mail ~]# mail [email protected]

Subject: dskjaf

skdja

.

EOT

[root@mail ~]# mailq

Mail queue is empty

[root@mail ~]# mail
