Uhm, .NET has been installed on every version of Windows since Windows 7, so it's unlikely that .NET has to be installed. If people are running old machines, then it's even more likely that .NET is already installed since there are so many applications these days that rely on .NET.

>I actually did buy the WestWindClient Tools. But I cannot use it in this project because it requires .NET frameworks to be installed on the computer. Some customers may not want to go through the installation of .NET. So until I can be assured that each customer will install .NET on their computer, I have to stay with the old wwIpStuff.

>>If you're using GMail you need TLS. The old wwIpstuff library doesn't support that. The newer wwSmtp library that's part of the West Wind Client Tools (https://west-wind.com/WestwindClientTools.aspx) supports it and it has the **same** interface as wwipstuff - you basically just change the class name. wwIPstuff is so old there wasn't even and official TLS authenticated protocol at the time, so probably time to upgrade to something a little more modern :-)
