I am guessing that they want a name with out the numbers. I have seen this before. They probably do not care about the name matching the HELO string but they do not want the IP Address in the reverse DNS. In may cases theis designates an address that is available and is not actuall in use.
Change the name so it does not have the ip in the reverse name. The IP servers no purpose in the revers name.
