I don't think you need to use tabs (spaces will do).

My default value is 500 messages/hour but I am thinking about lowering 
this quite a bit.

You need one more thing for it to work: put a job in your cron.hourly 
directory to clean things up.  The script can be found at the end of 
CustomConfig.pm.  If you omit this script you will not permit banned IP 
addresses to regain the privilege to send you mail.
