Why don't you use the statements given in the default configuration
file? No need to reinvent the wheel.

If you want to give a temporary error, then you have to use the "defer"
instead of the "deny" statement. Check the spec for more info on how to
write your own ACL rules.
BTW: You have to be a paying customer to be able to access the MAPS lists.
