@nprofile1q... Well it was chugging along just fine for many years. I suspect 20 years ago it would have been hard to find a "cloud" email provider that does everything I want from it. Even now it's not like I was choosing from dozens. So quite possibly I would have had to switch a few times between 2006 and today, undoing the benefits of outsourcing this.
Or maybe not, maybe I could have switched a long time ago…
