I think that Milter would be the way to go (no risk of losing email
because Postfix stays the "owner" of the message). There are Python
and Perl implementations, which is convenient if your filter is
also in Python or Perl.
Milters typically listen on a network port and want to accept
connections themselves, so they would not work under the spawn
daemon which accepts connections before creating a child process.
It's not possible to accept a connection in both spawn service and
in its child process.
