Hi,
You can use CDOSYS instade of CDONTS on the windows 2008 server. CDOSYS is Microsoft's new and improved interface for SMTP email which was introduced in Windows 2000.
Let me give a few reasons:
* CDONTS has been deprecated in IIS5 and is completely removed from Windows Server 2003, it is possible to install on Windows Server 2003 but with the performance improvements and other enhancements, there should be no need to do so.
* CDOSYS carries less overhead than CDONTS.
* HTML functionality is much improved with automatic generation of the TextBody by just setting the HTMLBody property.
* There are some new properties and methods that should have been included with CDONTS but weren't.
About Jmail , it is third party mail components and it is require license, if you have then you can install on the server. I trust on the ASPEmail or ASPMail they are very easy to use in code with impressive functionality.
