postfix always allows the connections before any rules are checked, so it will be very difficult to get these entries *not* in the log. What you *can* do - if you're using linux - is using iptables/ipchains to disallow acces from these ip's (or ranges) for a specific amount of time. A small script can do this for you ... or if you prefer a graphical firewall solution you can look at www.fwbuilder.org, is very easy to install and use...
