What does "differently" mean?

Content filters and routing have nothing to do with recipient validation.
Recipient validation is based on mechanisms described in:
http://www.postfix.org/ADDRESS_CLASS_README.html
with additional information in:
http://www.postfix.org/VIRTUAL_README.html
http://www.postfix.org/ADDRESS_REWRITING_README.html

You were given bad information.

The question is based on a false premise. What problem are you really
trying to solve. I thought you originally wanted a particular recipient
domain to favour relayhost over content_filter, that is not possible,
don't set a content_filter if it does not apply to ALL mail.
