this is why i dont like go daddy as a hosting provider.
it is their server, they should be able to configure it for their customers, that is after all what you pay the host to do, maintain the server and configure the settings properly
any decent host with decent support would fix this problem for you.
if go daddy will not fix this for you they should at least give you documentation to be able to fix it.
It is not something I can fix on this end.
this may help though:
