This is false. Amavisd-new has been highly optimized.

Postfix supports restriction-classes. I recommend you avoid taking that
route. Use Policyd opt-in + opt-out + Amavisd-new. Amavisd-new's spam-lover
supports exactly what u want, the messages will not be passed onto
SpamAssassin but instead will just be bypassed.

As for spam folder, you'll be looking to use Courier maildrop.
