SpamAssassin

Our mail servers automatically scan all mail and add a special header called X-Spam-Score: that contains a numeric spam score (the higher the number the more "spammy" the message is). For example:

X-Spam-Score: 12.5 (++++++++++++)

If the spam score is 5.00 or higher than a second header named "X-Spam-Report:" is added that looks like this (yes, it spans multiple lines):

X-Spam-Report: Spam Assassin details:   (12.0 points, 5.0 required)
