The 1.2.3.4 box, if it's running Exim, has 'verify=sender' set somewhere. Or some equivalent functionality. If you do the same on the relay box, you'll reject the same class of message. Note that verify=sender doesn't cause callouts - just DNS lookups of the sender domain. The domain grounddesigns2000.com's dns is broken. A perfectly valid reason to reject their email, in my view.
