Who supplies the public IP address for you? You need to apply for Reverse DNS Lookup for that public IP address.

You need to ask your hosting company regarding the Reverse DNS Lookup service.

Besides, you need to check with administrator of that particular domain which send you the NDR on whether your new public IP address is included in their black list of blocked IP address.
