Yes, it's a generic name. Yes, I have thought about changing it. Why did I name it this? Because. At the time, I was sick of obscure names for command line arguments. In hindsight, it makes sense to name it something simple, yet unique.
What is it? It's a command line SMTP client that support TLS, SMTP AUTH, Attachments, encryption with GPG and some other basic features. It was created originally to be a very simple SMTP client for mailing reports by a nightly crontab. It has grown a bit, but has stayed pretty simple. It's written in C and depends on my own C library called dlib. I don't code on this project as much as I used to, but I still do keep it up to date by fixing bugs and doing the occasional feature enhancement.
