I understand it is a tough questions.

Another approach, then. Would it be possible to receive a hash of the password, in Dovecot post-login script?

This might be used to decrypt the encryption key in the user directory.

Hello,

I have a question about the "mail-crypt-plugin".

If each user is having its own mail encryption key, is there a way to encrypt the key with the user password, and to decrypt it when the user logs in?

I want to, if this is possible, to prevent any user, even root, to access another user's emails.

Thanks, André
