1. postfix will reject 90% of the spam during the initial handshake

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.

Bye
