Enable Log?

[beate]

Hi,

As I got ino single email yet from the shop, I looked into the source of the mail functions (swift.php and so on) and saw a log which could be enabled:

if ($this->log->isEnabled()) $this->log->add("Message sent to “ . $sent . “/” . $total . “ recipients”, Swift_Log_Base::NORMAL);

I think this could be useful fo find my problem. Where can I enable it?

Thanks
Beate
