Creating new ticket by reply email

Creating new ticket by reply email

Hi,

I don't want to tell support@xxx.zohosupport.com to my customers.
So I add the support mail address in Bcc field when I replied to the new ticket request.

It seems work fine, the new ticket is creating by my reply.
But the Zoho desk think I am the customer.

So contact shows my information, not customer's information.
I'd like to see the customer's contact in the contact field in the ticket
How can I fix this?
