1. postfix will reject 90% of the spam during the initial handshake stage - by using a variety of dns / mx resolution tricks 2. clamav and spam assassin integrate into postfix so that you don't have to accept the spam the server can even issue a 550 in the middle of the data stage 3. using some known blacklists like spamhaus and rbl will cut down spam to 99.9 %
Well, my current stats say: User unknown: 25 % RBL-blocked: 32 % keyword blocked: 1 % other blocked: 24 % locally delivered: 17 % So a "cut down to 99.9%" is a bit pessimistic (filtering only 0.1% out) - if you meant "cut by 99.9%" too optimistic. But cutting off 82% even before the DATA command is not too shabby. OTOH it is a sign on how bad mail has become if more than 80% are plain junk even without looking at the content.
