As you can see in the NDR this message is coming from the recipients mail server. Get the recipient to check there spam list as you can see "Spoofed sender" reply back. There is nothing you can do from your end.

Also it might be wise to check and see if you are blacklisted from other spambot sources on the internet, using www.mxtoolbox.com.

Have checked the blacklist and they have come back clear.

You mention getting the recipient to check there spam list, how do you mean? on the server or client?
