I’ve been seeing comments about mailing lists. They usually want plaint text emails like these.
Receiving email, the service provider has full access to the metadata agreed. The main difference between proton and tuta is what data is kept encrypted at rest.
Proton does not encrypt the metadata, from, too, subject
Tuta does encrypt all of that metadata at rest
The clients are open source, you can do anything you want, you just have to implement it. I don’t know where the hate is coming from. Tuta is unique being the only email provider that encrypts all the data at rest, and I want to give them a lot of love for that, I don’t understand the hate at all
At the time of sending the mail I need the metadata - so offering a SMTP server implementation which keeps this in memory while forwarding is not hard. You’d lose a persistent spool in case of delivery errors - but we’ve been doing relays that keep the client connection open while trying to deliver the mail to relay errors directly to the client already 30 years ago, so that also isn’t an excuse.
For IMAP - if you don’t do serverside searching or similar it’ll work with fully encrypted mails.
