Mastering Microsoft Exchange Server 2007 SP1

What scares users more than the boss? Viruses, junk mail, and outgoing messages containing confidential information! These products let you catch mail-borne viruses, spam messages, and messages with sensitive content in their natural habitat: your Exchange server. They automatically download and install virus updates. Most also scan for viruses in real time as messages pass through your Exchange server and can perform scheduled and on-demand scans of information stores for viruses.
