Suggested end user feature E-Mail "report as SPAM"

All of the major E-Mail security companies have a feature where users can click a button to report SPAM.  I am seeing multiple phishing emails coming through the Websense E-Mail Security Gateway.  Users are constantly E-Mailing me and asking that I block the messages.  It would make sense to have a place where they can click a button in Outlook and have the message sent to Websense as SPAM, for review.  Additionally, when I identify SPAM, there should be a button that allows me to send the message to Websense as SPAM.
