it is the first onw that responds.
if it's a whitelist (scoringnegatively), it's reported anyway.
that's where postscreen_dnsbl_reply_map is to be used.

Thanks for clearing that up. My whitelists always cause a pass so for me
the whitelist reporting issue doesn't arise; for systems where it does, I
suppose the idea is to substitute the name of a blacklisting rbl (or some
generic text such as 'unidentified_blacklist') if the response would
otherwise show the whitelist?
i guess the original idea was to hide dnsbl secret from clients
(http://www.postfix.org/postconf.5.html#postscreen_dnsbl_reply_map)
but replacing message by e.g. "blocked by multiple dnsbl lists" is also
possible.
