If a user resets their single password or encryption password, they lose access to their previous e-mail. This is because what essentially happens is that a new PGP keypair is generated and the Secret Key is encrypted with the new password. Since we do not have their old, lost, password we cannot access their secret key to decrypt the e-mails (and subsequently re-encrypt them with the new Public Key).
