I too have an eternal email address from a professional society where I'm a lifetime member. I've used that address for nearly 30 years where it has pointed to various mail systems over time. I assumed that Proton would have this functionality as well, as it's just so basic, so I'm really shocked it does not. Now feel bad that I got a paid account before finding this out. I suspect that they have not implemented this because doing so completely eliminates end-to-end encryption, but the fact that they have not said as much does not speak well for them, and that could be dealt with through simply informing the users -- I want to be able to make an informed choice between confidentiality and availability.
