I've been using plesk since something like version 2.x or such, it's been well over ten years. Over those years, we've started using less and less of it, hosting our sites on standard Linux servers and using plesk mainly only for email. While the SUS is not that expensive, it's still yet another cost that we have to pay every year and it all adds up. Not to mention that the panel is becoming quite complicated to use when all we use it for is email really. None of the other features have much value to us. In fact, I could even move our mail to qmail-toasters which I also host on our network except that a couple of people like the GUI of plesk. So, my question is this. I have kept my install fully updated along with the OS. Everything works as it should, we really don't need any more or new features. If I allow the SUS to die, will the software continue to work and I simply no longer get updates or will the software stop functioning altogether at some point? I have to believe that since I've paid for the software and am now paying for updates, that the software is already paid for hence, should never die, I simply don't get any more updates. I wanted to ask here however because I don't like surprises or marketing talk/hype from sales. Any input would be most welcome and appreciated. Thanks.
