*Yawn* OP's problem isn't that his server doesn't 'work' OP's problem is that he *could previously* deliver, and no longer can do. Now even an obsessive-compulsive Merchant Banker might - just maybe - ... want to take his laptop on any connection WITHOUT a PTR RR and telnet smtp to either of the two *specific* yahoo MX the OP listed as problematic. .... and again from a server WITH a valid PTR RR. Yahoo at one time passed around a billion zombot messages every day. Now, bless their cotton socks - and connection vetting - they no longer do so. You call that 'paranoid'? I call it smart.
