Abstract:
1. A method executed by a processor for management of e-mail messages having embedded classification metadata, the method comprising: receiving a query from an end user to access an e-mail account by an e-mail client; determining whether the query has come from an insecure e-mail client; retrieving access rules for defining classification access restrictions for the e-mail client to access e-mail messages in the e-mail account, when the e-mail client is determined to be insecure; and modifying the received query, before sending to an e-mail server storing the email account, the query being modified based on the retrieved access rules to exclude retrieval of e-mail messages based upon the embedded e-mail classification metadata; sending the query to the e-mail server; receiving e-mail messages from the e-mail server based upon the query by sensitivity associated with the classification access restrictions of the e-mail messages determined by inspecting classification metadata embedded in each e-mail message; and sending the received e-mail messages to the e-mail client.
