Email Split Routing help

Email Split Routing help

Hello,

I have been looking all over the zoho documentation and forums throughout the internet to try to find my answer. I have my mx dns settings pointing at zoho correctly and have my account verified. My question is while setting up email routing to split delivery, i am getting confused about what the "Destination to route the emails" is suppose to be. Lets say my domain is "awesomedomain.com" but when i set the Destination to that domain it says 
 " The hostname you provided points ZOHO MX, please change hostname."
My DNS is on amazon aws route 53, My mx records are okay as i am getting emails the accounts that have been created. The issue is that if they account is not created, the emails are bouncing. I want them to go to the admin of my account if they do not exist. 

Please help

Thank you!
