Unfortunately you did not specify the IP address of the affected server. If it is the same server your message here was sent from, then you should make sure that it has a forward-confirmed reverse DNS, that is the IP address 194.95.6.10 of the server should resolve to a name (preferably of a organizational domain which has a legitimate looking website with some contact details), and this name should resolve back to the IP address. For 194.95.6.10 this is not true.
