Another alternative to milters is the postfix policy daemons.
The best one to use for block and reject is policyd-weight.
found here http://www.policyd-weight.org/

This gives spam a weight based on a number of factors.
I setup to do this
score <0 accept immediately
score <10 greylist then verify sender, then spf, then spamassassin if not
spf pass.
score >10 reject immediately
