It appears you are sending from root@machine.mydomaine, when the receiving server does a reverse lookup on this address it will fail as it is not valid and hence the mail will be rejected correctly with the error you have given. Ensure you have a valid server name/domain for your server and that it can be looked up in dns both forward and reverse.
