Easily, if they can be acessed via DNSBL/DNSWL qeueries. Any 'new'
lookup mechanism will have to be added through a postscreen policy
plugin, and that involves new Postfix code.
For context: Postscreen decides if a remote SMTP client is allowed
to talk to a Postfix SMTP service. The decision is made on (protocol)
behavior and reputation, plus a static allow/deny list that is
typically populated with information from major provider SPF records.
