Kaltura CE email not sending

Hi,

Not sure I understand. Are you saying that a script like:
<?php
mail ( 'your@mail.com' , 'subject' , 'message');
?>

Works and you are not getting emails from Kaltura? do you see a sending attempt in /var/log/maillog? if not, did you look at /opt/kaltura/log/kaltura_api_v3.log to see if an attempt to send an email was made?
