Hi Heiko, Hi Andrew, thanks for your answers! At first, I wasn't aware that Exim has such fancy concepts for on-the-fly modification of messages. Mybe I'm missing the point. The on-disk representation of the password is a hash. That can't be used for symmetric encryption/decryption. You

[exim] Storing messages in Maildir format with symmetric encryption

2022-11-23 Thread Dengler, Gabriel via Exim-users
Hello everyone, I want to store the incoming e-mails using the Maildir file format encrypted by using some symmetric encryption using the user's password (e.g., AES). So in the end, Exim should write the encrypted files directly on the disk. Furthermore, it would be convenient if the actual
