You're welcome, I'm sorry to hear you had so much trouble with this. Ideally when installing SmarterMail you'll want to create a new site, unless you already have an existing SmarterMail site set up in which case you can have it configure an existing site. Previously SmarterMail included a built in web server, but being that this is no longer pre-packaged with the product you do need to have some IIS knowledge to work with the product. Please don't hesitate to ping us/our community if you have any other questions along the way.
