Encryption at Rest with S/MIME or OpenPGP Added to Stalwart Mail Server

Excited to announce that Encryption at Rest has just been added to the open source Stalwart Mail Server. With this addition, the mail server will now automatically encrypt all incoming plaintext emails, utilizing either OpenPGP or S/MIME, before they are written to disk. Importantly, the keys are owned and controlled by the end user, ensuring that not even system administrators can decrypt these messages.

I'd love to hear your thoughts and feedback. Thanks!
