Messaging has moved from the realm of a ???nice to have???
service to a business-critical application that serves as the
communications lifeblood for many organizations. It no
longer is acceptable for email services to be unavailable for
lengthy periods of time or for performance from the email
system to be slow and unresponsive. At the same time, the
demands for new and better methods of getting to email
keep increasing, putting additional strain on messaging
administrators who are tasked with providing secure, reliable
access.
