You really should have full 'circular' dns if you are going to run an email server. Is it required by the RFC's? no, it most certainly is not. But many people check on it and refuse on it. And that naming scheme they are using will trigger a LOT of filters out there besides the missing circular DNS.
You are the customer. Tell the salesdroid to fix this problem or you will not change to them. You really need to draw the line on this one, imho.
