There is a form to send email, it is centered around using an external email provider. I have set it up so that it puts the requested data, (type of info requested, name, email, etc) and puts that where it belongs in the users own default email client. (generally Outlook). We have our own SMTP server.
My question is what is the simplest approach to get email sent using the form? The server is Windows server 2016, IIS. I have looked up stuff and see PHP, ASP it's kind of crazy how complicated it gets. Maybe I have not found the right tutorial.
