This session covers three main topics. We start with a look at message hygiene. Your e-mail system is constantly being bombarded with unwanted messages, and as a messaging administrator, it is your job to prevent that. Next, we discuss messaging policies. Following recent accounting scandals and the global terrorism threat, governments and their agencies require organizations to store, and produce upon request, pertinent e-mail messages. Microsoft Exchange Server 2007 provides policies to achieve this goal with policies that are simple to set up and administer. Finally, we look at how messages can be made secure while in transit through your organization, between organizations, and across untrusted networks, such as the Internet.
