Making a decision based on different attributes is better done with
amavisd-new and spamassassin (the Postfix 2.8 postscreen daemon has
support for DNSBL/WL weighting, but it does not allow other factors
to speak in favor of a specific message). The Postfix features are
best used for mail that you definitely don't want to receive.
