SMTP/NNTP Transport Event Sinks with CDO

[This is preliminary documentation and subject to change.]

Implementing and managing SMTP/NNTP service transport event sinks using CDO is covered in the CDO for Windows 2000 documentation.

Transport event sinks implemented with CDO for Microsoft® Windows® 2000 will continue to function without alteration after the installation of Microsoft® Exchange 2000 Server. 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 2000 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 2000, it is recommended that you update any references to the CDOSYS component, and replace them with references to the CDOEX component. The following list outlines these references:
