For those interested, Mozilla is planning a similar service (though still invite-only at present): https://relay.firefox.com/

Can't wait for it to become available. I'd even pay a subscription to make it sustainable.

can you invite me ? email in profile ;)

Sorry, I don't have an invite yet either; I don't know how those get allocated. I'm just keeping an eye on it for it to become available.

And all for the low low cost of a MITM

Like any other hosted email client.

I am not sure I understand, can you please explain (or link me?)

If Apple can redirect the email to you, they can also store and read these emails.

By that logic so can google with gmail: of course they can, but that’s why we have to put some level of basic trust in our email providers. If you don’t want an MITM, you’re basically stuck with PGP or hosting your own email service.

Lavabit used to not be able to do that, and Protonmail can't either still... (To be fair, Lavabit _could have_ made changes so they could do that, but the owner refused when law enforcement asked him to do that fpr Snowden's email, and risked very real threats of jail instead. I don't think Protonmail have been tested lie that yet, but they have at least incorporated outside of US jurisdiction,which changes their risk in some important ways...)

If you use Apple SSO but your email is hosted elsewhere, Apple has introduced themselves as a MITM for your email. Facebook SSO doesn't do that.

you can use apple sso with the real e-mail too, as far as I remember. it’s an option.

Oh sure, it's just that it adds another "man in the middle", where previously there was only your own email provider.
