for spam and malware, and from all content and message filtering, select that list. 

This setting does not cause the message to bypass anti-spam or Outbreak Filters processing generally. 

Submit and commit your changes. 

If you have met the applicable prerequisites, and you have already configured Outbreak Filters and 
Anti-Spam protection, then you do not need to make additional configurations to benefit from enhanced 
detection of spam and malicious URLs.
