Business runs on e-mail. However, few organizations are satisfied with their e-mail system. To meet security, performance, and availability expectations, an e-mail system must address many business risks:

• E-mail is a target for virus, worm, and spam attacks
• Outbound e-mail is at risk for interception and alteration
• E-mail must meet legal requirements for records retention; government agencies or the courts can subpoena e-mail
• E-mail outages instantly affect every employee, manager, customer, or business partner of the enterprise

Because of these risks, careful enterprises surround their e-mail systems with additional services to secure and harden them. This white paper describes HP's set of add-on Microsoft Exchange solutions built on HP products and services that protect against these risks and enable e-mail administrators to set and better enforce message handling policies.
