• Security enhancements introduced by Microsoft Exchange 2003 Server include Internet Protocol security (IPsec) support for front-end and back-end clusters, signed Lightweight Directory Access Protocol (LDAP) requests to Microsoft Active Directory, front-end and back-end Kerberos authentication, IIS 6.0 protection, limiting of distribution lists to authenticated users, real-time Safe and Block data, inbound recipient filtering, attachment blocking in OWA, and public folders access enhancements.

Advantages of MS Exchange 2003 Compared to MS Exchange 5.5
Exchange 2003 Server offered significant enhancements in capability over Microsoft Exchange 5.5 in key areas affecting access, ease of management, protection, reliability, scalability, and performance.

• MS Exchange Server 2003 offers a dramatic increase in functionality compared to the Microsoft Exchange 5.5 web client. MS Exchange 2003 Server offers a nearly identical implementation of the traditional MS Outlook GUI interface that features calendaring and tools. As a result, mobile workers get the advantage of full, protected access to email even without a notebook. All they require is an Internet-attached computer with a standard web browser.
• Unlike MS Exchange 5.5 Server, which has a built-in directory, Microsoft Exchange 2003 Server utilizes Microsoft Active Directory, representing a more streamlined administration and security structure. This makes MS Exchange 2003 Server easier to manage and maintain and in addition allows better security.
• Microsoft Exchange Server 2003 has a strong foundation for transparently integrating third-party utilities such as anti-virus and anti-spamming software. Exchange Server 2003's versatile Application Programming Interface solves the instability associated with MS Exchange 5.5 Server when integrating independent utilities.

• Unlike the store-and-forward technique utilized by POP3 email environments, MS Exchange 2003 Server uses a central-store model that frees users from dependence on a specific desktop computer or notebook, lowers susceptibility to hardware failure or virus attacks, and permits both on-line and off-line email, programmed backup, and advanced groupware.
• Microsoft Exchange 2003 Server has an array of collaboration features that allow work groups to maximize efficiency by sharing calendaring, address books, correspondence, and files.
• The flexibility of Exchange Server 2003 makes it possible to integrate third-party security enhancements or support wireless computers such as the RIM BlackBerry.
