Does the recipient MTA actually receive for both klop.yi.org *and* thuis.klop.ws? The recipient MTA will dereference the CNAME and rewrite the envelope for the reason that it can only relay to an RR that points to a real host.
You might be able to fix it if you configure the mta on thuis.klop.ws to accept mail for the thuis.klop.ws domain in addition to klop.yi.org (which I assume is how you have it setup). In a situation like this if you have domain CNAME originaldomain then you better make sure that someone can send to either @domain AND @originaldomain otherwise it doesn't make sense.
