The way I look at it is that we're gonna have email for a long time, realistically at least another 50 years, probably 100. So if we're stuck with it, we might as well make it as painless as possible. I totally agree that we should look for better protocols, for example Matrix looks like it could eventually be a good replacement for email. But whatever email is replaced with will definitely need some kind of way to interface with email during the transition, and a pre-built mail reverse proxy / IP gateway will only help with that.
