For general redelivery of a mail spool, fetchmail might do what you want.
Accurately redelivering messages to a server with the express purpose of
testing it's filtering system with regard to the original delivery seems
extremely hard. One problem is that the filtering systems today generally do
quite a few live checks of remote resources to determine spam, which you have
no way or guaranteeing are the same. The other is getting the SMTP daemon
(postfix in your case) to treat the incoming messages as if they were coming
from the correct remote location.
If there's something out there that does it though, I'd definitely be
interested.
