dedyk That happened to me too. When changing the password, the user is unable to log in to the email. When checking the database, the password is recorded without encryption.
When trying to activate "dovecot" encryption I get the message: "Could not save new password. Encryption function missing."
Checking the error log, I realized that PHP is not able to write to "/ dev / null". I already changed the file permissions, but it has no effect.
I also tried to edit the password.php file, changing the destination "/ dev / null" to "/ tmp / null" and it also has no effect.
