It is not the first time that I'm bitten by this, but I never understood

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

mandatory and only sendmail seems to do it.
I think it is lame to use DNS info to rewrite e-mail addresses, but the
person who made it 'mandatory' will have good reasons for it.
Does somebody have a pointer to the specs about

Because it used to be manditory to do so. If you don't want it to
be done use a MX record.
klop.yi.org MX 0 thuis.klop.ws
If you need klop.yi.org to have a address record then giv
offtopic, but why do some mailers replace a CNAME in a mail-address?
