I am at the airport and have another 15 minutes before boarding, so here we go :)
You are referring to three distinct features:
1. Disallow access from IPs in black-list must be turned on for the black list to have any effect whatsoever.
2. The logging option controls whether to log the 403s or not.
3. There is the "Email this address on security exceptions" field. If you leave it blank, you will no longer be receiving emails about security exceptions, including IP blocks.
So you just have to leave the "Email this address on security exceptions" field blank to achieve what you want. I hope that makes sense!
