Exchange Server 2003 allows Outlook 2003 clients installed on Windows XP Service Pack 1 and above full MAPI client access to Exchange Server 2003 resources using the new RPC over HTTP protocol. RPC over HTTP allows the RPC commands required for full Outlook 2003 MAPI client access to be wrapped or "encapsulated" in an HTTP header and passed through proxies that allow outbound HTTP/HTTPS (SSL). ISA Server 2000 is the ideal firewall to provide the highest level of protection for your Exchange Servers while at the same time allowing the rich functionality the Outlook RPC over HTTP client provides. Check out part 1 of this series on how to configure the ISA firewall to allow secure RPC over HTTP connections to your Exchange 2003 Server.

Spam is a major threat to the Internet and corporate networks today. Spam clogs Internet routers and gateways, usurps bandwidth on corporate Internet links, and consumes processor cycles and disk space on corporate SMTP relays and mail servers. Criminal spammers are using increasingly sophisticated techniques to circumvent spam filtering applications. The more complex the spammer’s attack methodologies used to avoid detection, the more processor intensive the spam whacking applications must be. These processor cycles are robbed from other applications and services running on the same machine and often require that you dedicate a single box to spam filtering. This two part article shows you with detailed step by step instructions on how to make your ISA Server 2000 firewall into a front-end spam filtering SMTP relay.
Although all of us Exchange administrators would like to have Exchange as the sole mail server, sometimes more SMTP mailers exist. The following article explains how to configure Exchange to relay mail for these systems.
Virus, Trojan and denial of service attacks are quite common these days and Exchange is a popular target for these attacks due its popularity and inherent vulnerabilities. Mail relays can be used to thwart most attacks. I'm constantly discovering that although the concept of mail relays is not new they can be used against the latest sophisticated attacks, just long as they're not the weakest link in the chain of e-mail delivery.
With Exchange 2000 SP2 Microsoft added a feature, known as segmentation, that allows you to quite easily make some rather major changes to the appearance and functionality of OWA.
Not everyone has managed to migrate to Exchange 2000 yet, while others choose to ignore it completely, and continue using Exchange 5.5. Meanwhile, Microsoft has introduced a new upgrade – the 2003. This is related to the appearance of a new MS Windows 2003 version, the operating system to provide a really good tandem with Exchange 2003. As we will see further on, when using Exchange 2003 without combining it with Windows 2003, it loses most of its functionality.

Migration from Exchange 5.5 to Exchange 2000 was a bit of a headache for those who tried it, especially using the early versions of ADC, the component used to synchronize Exchange 5.5 and Active Directory. Microsoft will soon release Exchange 2003, which is not a great leap in design as Exchange 2000 but basically, the same product with some additional capabilities, improved web interface and Windows 2003 operating system support. The Exchange 2003 ADC has evolved to make basic migration scenarios more easy using automated and wizard based mechanisms. Let's look at some of the changes.
In this article we will look at how we can modify the DisplayName field in Active Directory to use the LastName, FirstName format, this will then ensure that the Address Lists used by your users will be sorted by LastName.
Out of the box, most email server products provide limited monitoring, security, and anti-spam functions. In those that do, the feature set tends to be weak and seemingly implemented as an afterthought. However, the new GFI MailEssentials 8 product from GFI Software not only provides the most comprehensive anti-spam capabilities currently available, but also industrial-strength mail monitoring, the ability to add disclaimers to all outgoing messages, and more. Impressively, GFI provides many of the product's best features as freeware, making GFI MailEssentials 8 a must-evaluate product for administrators of both large and small networks alike.
The need for email disclaimer messages is now fairly well established, yet there is still no built-in facility for configuring them in Exchange 2000. For this review, I have chosen to look at eXclaimer, a product that receives regular mention in the Exchange Usenet newsgroups.
