[求助] 如何让MD判别哪些邮件是SPAM

建好MD服务器后进行163.com 126.com 21cn.com等大型邮件供应商的账号对MD服务器进行发送测试发现如果用客户端软件比如FOXMAIL发送邮件过来的话可以收到，但是登录到这些邮件平台上，从WEB页面发送邮件过来就都收不到，查看来日志如下：

上面的黑体大字中显示是此信被判定为垃圾邮件，便进入MD中查看设置

已经选择了判定为垃圾邮件后继续下传了，怎么还是收不到邮件？
难不成我要在白名单里把所有可信域都加进去？那不是很累？敢问一下各位先人，如何对叶斯贝的过滤进行整理，又如何对启发式进行定义？根据日志中对SPAM分值的定义，难道我要将在“启发式”页面中的“邮件是垃圾邮件的条件为其总值大于或等于”一直改为14分？
