My guess is that the server you are sending to is one of those tulipe ones that bounces mail back if you don't have an SPF record set up.

Google it to find out how to add one quite simple (and largly pointless)

Right, I may be talking a load of crap here but...

looking in to it now, the only thing I can think of is it might be something to do with us having his site set up ready to go on our server confusing the mail server. odd though, no one else I know has had issues sending to us so unless it's the above I'm stumped?

My plan B server on www.<myplanb>.com was having issues sending out mails as they were treated like spam in some places until I changed the mail server name to mail.<myplanb>.com.

I cant work out which side is sending the non-delivery report. Can you reword the NDR so that you show either destdomain or sourcedomain.

I suspect that the recipient email server is doing a reverse-DNS lookup on your mailserver and finding something it doesnt like and rejecting it. You used to be able to use www.dnsreport.com to check your domain status to make sure that everything is setup correctly, but now they charge a fee for this. You may be able to find another one.

Another possibility is you have been added to come blacklist that they are subscribing to
