Hi Jess,
Thanks for the reply and Kaltura works now 
Does all-in-one Kaltura box need to be able to send email out? Because I don't have email service and i'm using gmail for all my email needs. When I add a new publisher it say it will send an email to the address but i didn't really setup the email function as i don't have any.
Please let me advise what can be done.
Thanks
