CDONTS

CDONTS is a library (component) provided as a part of IIS starting with Microsoft Windows NT 4.0 Server using Option Pack 1 up to and including Microsoft Windows 2000 Server. It works in conjunction with the Microsoft SMTP Service under the IIS Internet Information Manager console.

CDONTS is a free component of IIS that lets you run an SMTP server on your website, or more to our point, provide a way for ASP applications to send SMTP email messages. CDONTS can be used in conjunction with any existing SMTP server software on your (or your ISP's) same network or server as IIS. CDONTS is being phased out and replaced with the newer CDOSYS library.
