Constant Brute Force Attacks

So DirectAdmin has this feature where it scans the logs of process such email, ftp, etc. This great security measure is abusing the h*ck out of my inbox. And in turn all these constant emails about brute force attempts is making meĀ  extra paranoid. So looking for a way to turn on auto ban so I can at least temporarily block the abuser. Found some interesting scripts online. http://help.directadmin.com/item.php?id=404 http://help.directadmin.com/item.php?id=380
