Issue in ajax_get_json.php when $dkim_strength = 0
Reported by M Roji:
I found some bug, that make my script not working properly.
The bug is the code in file /usr/local/ispconfig/interface/web/mail/ajax_get_json.php
$dkim_strength = $app->functions->intval($mail_config['dkim_strength']);
if ($dkim_strength=='') $dkim_strength = 2048;
The right way is
$dkim_strength = $app->functions->intval($mail_config['dkim_strength']);
if ($dkim_strength==0) $dkim_strength = 2048;
