阿里云的审核速度还挺快的，两个多小时后反馈结果了，不过看看就吐口老血！！！
只能想其他的办法呗！！最后决定使用163邮箱的465加密端口
[root@orcherstrator ~]# telnet smtp.163.com 465
Trying 220.181.12.14...
Connected to smtp.163.com.
Escape character is '^]'.
^C
Connection closed by foreign host.
root@orcherstrator ~]# nc -vz -w 1 smtp.163.com 465
Connection to smtp.163.com 465 port [tcp/urd] succeeded!
看样子有戏哦！！！修改/etc/mail.rc的配置
set from=admin@163.com
set smtp="smtps://smtp.163.com:465"
set smtp-auth-user=admin@163.com
set smtp-auth-password=xxxxx
set smtp-auth=login
set smtp-use-starttls
set ssl-verify=ignore
set nss-config-dir=/etc/pki/nssdb/
[root@linux-node2 ~]# echo 'hello' |mail -v -s "test" yueyuancun@163.com

至此，网上的case都说能收到邮件，但是我这就是收不到，那就根据错误来解决呗！！！搞证书
[root@linux-node2 ~]# mkdir -p /root/.certs/
