@Echedenyan@lemmy.ml yes, but there are few caveats with disroot. What is special about companies like Protonmail and the like is that they store encrypted emails on their servers. According to disroot’s privacy policy: “All emails, unless encrypted by the user (with GnuPG/PGP, for example) are stored unencrypted on our servers.”, so in theory there is more data that can be forced to handover. Another concern about disroot is that they don’t have the budget for expensive security audits, their mail server is NextCloud, and their web-mail client is Rainloop web-mail, the later doesn’t seem to be very actively maintained, so how secure is it? I don’t know.
Disroot isn’t security oriented.
