If 77.29.197.36 is your server ip then you have not setup your server properly. Your server IP should have at least an A and PTR dns record. It should also be listed in /etc/hosts with the hostname of your server.
 
The message simply means that there's no rDNS record for 77.29.197.36.

If the domain isn't under your control then there's really nothing you can do about it.
