1. A method for message security classification in a web e-mail access client comprising: opening a message form within a web client window of the web e-mail access client; receiving a user-generated event from the group consisting of send events, print events and save events; in response to said user-generated event, presenting the user with a popup dialog requiring the user to select a first security classification based upon predefined classification criteria available to the user for associating with the message form of the web e-mail access client; receiving a first security classification selection input from the user; assigning header properties to the message metadata associated properties based upon the security classification selection; determining whether a secondary classification is required based upon the first security classification input; receiving a secondary classification selection input from the secondary classification options selected by the user from the popup dialog; determining whether the security classification selection input and the secondary classification selection input are valid; and assigning x-header properties to the message metadata x-header properties are based upon the security classification selection input and secondary classification selection input when security classification selection input and secondary classification selection input are valid; wherein the security classification selection input associated with a portion of identified text within a text body of the message form and the x-header properties are assigned by association with the identified text in the text body of the message form.
