To enable the email account password change option from roundcube, you can edit file:
/usr/local/cwpsrv/var/services/roundcube/plugins/password/config.inc.php
Don't forget to replace your postfix user "PASSWORD"
$config['password_driver'] = 'sql'; $config['password_db_dsn'] = 'mysqli://postfix:PASSWORD@localhost/postfix'; $config['password_query'] = "UPDATE mailbox SET password=CONCAT('{PLAIN-MD5}', MD5(%p)),modified=NOW() WHERE username=%u LIMIT 1";
You can find your postfix password here:
grep pass /etc/postfix/mysql-virtual_mailbox_maps.cf
