Spam Scoring (what is BCL, SCL and PCL?)
These scoring tools are used specifically by Microsoft to determine the potential risks associated with incoming email messages to their network.
Bulk Complaint Level (BCL) - is the email from a bulk sender? On a scale from 0 (unlikely) to 9 (likely from a bulk sender that generates a high number of complaints).
Spam Confidence Level (SCL) - the likelihood that the message is spam on a scale from 0 (unlikely) to 9 (very likely).
Phishing Confidence Level (PCL) - is the email likely to be phishing? On a scale from 0 (unlikely) to 9 (very likely).
Messages that score 5 and higher for any of these levels are more likely to be filtered into Microsoft's Junk Folder upon being received.
