We have 2 support email address: support@mydomain.com and orders@mydomain.com that forward to corresponding support email addresses in zoho desk (support@mydomain.zohodesk.com and orders@mydomain.zohodesk.com). The email forwarding is working perfectly. Now, we just want to automatically assign agents.

Is there a way to assign a ticket automatically depending on which support email address is used? 

I've tried from address and channel criteria, but that has not worked. 

If someone emails the orders@mydomain.com email, I'd like it to automatically be assigned to a specific user.
