Symantec Messaging Gateway lets you add annotations to the content filtering messages that contain violations. To do so, when you create a policy you must select the action to add an annotation. For email, you can prepend the annotation to the beginning of the message body or append it to the end of the message. If you prepend, you may want to end your annotation text with a blank line or a line of dashes. Some type of separator between the annotation and message body provides the user a visual cue as to where the message body begins.
Annotations are different from policy violation notifications. Annotations are added to the message. A policy violation notification is a separate message that is sent when a policy is violated and the policy action is to Send notification.
