About Messaging Server

Sun Java System Messaging Server 6 is a high-performance, highly secure messaging platform. Scaling from thousands to millions of users, Messaging Server is suitable for businesses interested in consolidating email servers and reducing total cost of ownership of communications infrastructure. Messaging Server provides extensive security features that help ensure the integrity of communications through user authentication, session encryption, and the appropriate content filtering to help prevent spam and viruses.

With Messaging Server, organizations can provide secure, reliable messaging services for entire communities of employees, partners, and customers.

Messaging Server currently supports two client user interfaces (UI):

• Messenger Express

• Communications Express

Going forward, no new features will be added to the Messenger Express user interface. It has been deprecated in favor of the Communications Express user interface. Sun Microsystems, Inc. will announce an end-of-life timeline for Messenger Express at a future date.
