Im not receiving order emails from our website

Hi ever since I transferred my website and emails over to inmotion we havent received any order emails from the website. Ive talked with tech support and they say all the settings are correct but still n o emails. Its been since Sept 7, 2015. Can someone see if a file is coded wrong or maybe its because were having upgrading issues or what it is? But my boss is getting frustrated so I really need help getting this fixed. Any help is greatly appreciated!
