3.1 Client Details

The role of the client is to determine whether a message is a phishing message and to update the PidNamePhishingStamp property (section 2.2.1.1), as specified in section 3.1.5, to indicate the results of such analysis. The client then checks the value of the PidNamePhishingStamp property when the message is opened and conveys a warning to the end user for any message that is likely to be a phishing message.
