Check you squirrelmail with 'rpm -q kloxomr-webmail-squirrelmail'. If you found 'kloxomr-webmail-squirrelmail-1.4.22-5.mr' that this is the new one.
But you must read 'warning: /home/kloxo/httpd/webmail/squirrelmail/config_local.php created as /home/kloxo/httpd/webmail/squirrelmail/config_local.php.rpmnew' where config_local.php.rpmnew copy to config_local.php.
