As I mentioned on another tread, we had to change the IP Addresses of the server, The new IP Address that was assigned to us was "dirty" and as a result, Yahoo has blocked all email originating from this address.
I have logged a ticket with Yahoo, as did my Hosting Provider, we now just have to wait patiently for Yahoo to unblock us
