Sun Java Communications Suite 5 Deployment Planning Guide

SMTP Server

(Optional) An SMTP messaging server, such as Messaging Server, is used to forward instant messages, in the form of email, to end users who are offline. The SMTP server can also be used to archive instant messaging communications. This is in lieu of or in addition to the archive capability provided by Portal Server. The SMTP server does not have to reside on the same host as the Instant Messaging server.
