If you are using a Windows 2000 / 2003 Server, or even XP Pro chances are that CDOSYS is your best bet for sending email from Active Server Pages. That is because CDOSYS is installed on all of them by default. Gone are the days of using CDONTS which was the old way of sending email from ASP. CDOSYS is it's replacement. That being said there are actually a lot of ways to configure and use CDOSYS. When I 1st started using CDOSYS I assumed the CDOSYS code I was using would work in any situation, but that is not the case. This is something most articles about CDOSYS do not mention so I am going to show you 3 different CDOSYS examples each sending email using a slightly different method.
