Unable to receive email, MX records setup

Unable to receive email, MX records setup

I am unable to receive email at my domain teamshipstudios.com.  I am hosted through Dreamhost and have setup the mx records on my domain management portal.  I used this tool, as I have seen in other posts, to verify the mx records.  http://mxtoolbox.com/SuperTool.aspx  I am able to see mx.zoho.com mx2.zoho.com and mx3.zoho.com.  What else do I need to configure?
