I noticed that, when a message is tagged as spam, the X-Spam-Status header sometimes contains RAZOR2_CHECK, sometimes it doesn't. When RAZOR2_CHECK is included, there's usually a RAZOR2_CF_RANGE_* tag as well.
This leads me to believe that RAZOR2_CHECK actually means "this message has been identified as spam by Razor2". Is that true? If yes, the name of the tag is slightly misleading, it seems to simply mean that a check is performed against Razor2. -- Florin Andrei http://florin.myip.org/
