[求助]关于exchange智能邮件筛选器问题

redksy

在“性能”里，添加了以下：“智能邮件筛选器的性能计数器”<br>
Total Messages Scanned for UCE<br>
Total Messages Assigned an SCL Rating of 1<br>
Total Messages Assigned an SCL Rating of 2<br>
...<br>
Total Messages Assigned an SCL Rating of 9<br>
<br>
看到<br>
Total Messages Scanned for UCE的数值在增加<br>
但<br>
Total Messages Assigned an SCL Rating of 1-9的却始终为0。<br>
<br>
请问是怎么？
