Is there a way to monitor the postfix logs and block IPs that are consistently sending to bad email addresses? I see these popping up in my logs all the time, and am wondering if there isn't a way to monitor this and block IPs (even for a little while) that are sending to invalid addresses. I'm not accepting the messages, but I have to feel like they're going to eventually harvest valid addresses by sheer brute force.
Thanks,
