Tell HN: Proton is reading and filtering incoming mail

[reactchain]

This seems relevant to privacy-conscious folks here:

I just tried to use my existing ProtonMail account as a backup for my Gmail account. Instead of receiving the verification code, I got an email in my Proton inbox that says:

"Your Proton account is currently restricted from registering on third-party services"

Meaning that proton is actively reading (and filtering) mail from certain flagged accounts. Otherwise, how do they know my account just received a matching email from Google with a verification code?

This is not particularly surprising for most providers, but I was not expecting it from Proton. What's the point of all the encryption claims?

>What's the point of all the encryption claims?

The point is that _you_ read them carefully. They are true to their claims.

Subject lines of emails are not E2E in Protonmail, nor have they ever claimed them to be.

It's likely that and it's not really news.
