The Exchange Developer Center Web site at http:// is primarily intended for developers. It is the best place to go for the latest version of the Exchange 2003 SDK and a great place to browse the SDK documentation online and check out sample code written in C#, C++, Visual Basic .NET and VBScript.

In addition to the code samples, API documentation, and other content, this site also includes some development tools that get you started on building Exchange-based solutions, such as:

  • Exchange Application Deployment Wizard
  • Exchange Explorer
  • Exchange Store Event Sink Wizard for Visual Basic 6
  • Managed Exchange TreeView Control

Even if development isn't your forte, you may find the information on creating and using event sinks to be useful for your environment. An event sink is a piece of code (the sink) that executes (fires) when something (the event) happens. Exchange 2003 supports protocol event sinks and transport event sinks (for managing messages in the SMTP service) and store event sinks (for managing messages in the Exchange store). Protocol events occur at the SMTP command verb level between the client and the server, and protocol event sinks can be used to modify commands and responses to commands. Transport events occur as messages flow through the SMTP transport stack, and transport event sinks can be used to manipulate messages as they travel through SMTP. Event sinks are useful in all sorts of situations; they can be used to convert messages, scan for content, add disclaimers to outgoing messages, or reroute messages in a workflow environment. In addition, there is a Protocol Sink Template you can use to create an in-house antispam solution that accepts or rejects messages based on a spam confidence level. You can do with event sinks just about anything you would want to do with or to a message while in the SMTP transport stack or information store.
