[otrs] customer in CC filed in Customer interface.

I've been trying to setup some events to achieve the following: Initially i had created 1 free filed called CC. Actually i want to send that ticket to whatever emailID send by customer in CC filed. I Tried setting Recipient:(Email based) as if i tried to print that name in Body its showing it properly in Ticket Body. But if i insert it in Recipient email address its not sending notification to that Customer. that is if i'll give xyz@abc.com directly in Recipient address its sending Ticket Notitfication to that address but if i tried to send it through Free filed its anable to send Ticket. I'm not sure how to identify this in order to change the notification message accordingly. Any help on this questions is greatly appreciated. Best Regards, Vaishali Dolas
