You can put amavisd-new in front of postfix, acting as a proxy:

In particular, the pros and cons of that approach are listed here:

Doing so lets you reject spam immediately, but the trade-off is that it
requires more resources because you can't just queue up messages for
later scanning.
(This is "not supported" by amavis, but works just fine.)
