The header fields give this information about the message
• The overall spam score is 0.46800.
• The only junk mail filter triggered was the Commercial Offer filter (C).
• The user's Bulk Spam filter was set to Most Aggressive (5).
• The Effective threshold was 8.00000

header)
This message is evaluated as spam based on comparing the spam score (S:
0.46800) against the threshold value (8.00000). If the spam score is less than the
effective threshold, the message is considered spam. In this example, 0.46800 is
less than 8.0000, so this message is spam.
