Disabling and enabling predefined words or phrases in dictionaries
Predefined words and phrases are words or phrases that Symantec Messaging Gateway provides. You cannot delete predefined dictionary words or phrases. However, you can disable the predefined words or phrases that you do not want to use in content filtering policies.
You cannot disable user-defined words or phrases in any of the dictionaries (premium, custom, or user-defined). If you do not want to use user-defined words, you must delete them.
