AFAICT, it is not possible if the error was something like "

Nov  7 19:14:40 fc10 rpc.mountd: Fake hostname bogus.com for
192.168.1.1 - forward lookup doesn't exis

This is a security precaution added into the nfs package that lessens the
likelihood of unauthorized servers from gaining access to files on the NFS

nfs-utils-1.1.4/support/export/hostname.c
