There is a small perl script spamshield.pl (www.spamshield.org) that can 
(from cron) scan your maillogs and create a list of blocked ip addresses 
based on too many mail RCPTs.
You may be able to modify it to only block RCPTS for non-existing addresses.
We use a sh script to then add those blocked IPs to the sendmail access 
table for 24 hours...
