I think I said all you have to know - the one missing was just the
"domain dependent" thing.
Additionally, this rejects RBL listed mails - but I want to discard
them to /dev/null...

I know that. In this case, it's ok because it is a 100% spamtrap domain.
I'm not sure I understand your goal. do you really want to not reject
(421 or other) such mail at smtp time for some reason, or you don't care
if it's a reject or a discard? do you want to discard so that client
thinks the message was delivered (so it won't retry)?

Since I know Postfix quite good, I think this cannot be done with
Postfix features - you will need to expand it with SA and perhaps
procmail.
postfix has DISCARD action that you can use after SA. you can for
example let SA add its headers, and in the after-the-filter postfix, use
header_checks to looks for SA headers and discard mail if a match is found.
