SMTP/NNTP Transport Event Sinks with CDO

This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.

Implementing and managing SMTP/ Network News Transfer Protocol (NNTP) service transport event sinks using Collaboration Data Objects (CDO) is covered in the CDO for Microsoft® Windows® server operating systems documentation.

Transport event sinks implemented with CDO for Windows server will continue to function without alteration after the installation of Microsoft Exchange Server 2003. No recompilation or re-implementation of the sink is required. The CDO for Exchange 2000 COM component has been designed to install cleanly over the CDO for Windows server COM component, and all applications, including transport event sinks, will continue to function after the installation.

If you need to update or revise the code for applications written using CDO for Windows server, it is recommended that you update any references to the CDOSYS component, and replace them with references to the CDO for Exchange 2000 Server (CDOEX) component.
