You were just assigned a new junior systems administrator today to help out by performing some lower-level tasks. You have asked him to add several new words to the content filtering antispam agent on your Edge Transport servers so that those words will not be considered in the SCL score. After some time, you start getting calls from several hundred upset users saying they are getting a large influx of spam messages. You check several of the reported messages, and none of them contains the words you asked the new administrator to add.

What option in the content filtering agent did the new administrator most likely change to cause users to start getting spam when they previously were not?
