Did I get this right that this is just a "binary" switch to change the 
behaviour when the "BLOCK" variable is set?

If that's true, I would suggest to chnage this slightly so that both things 
can be done (use seperate variables).

The reason for this suggestion: When any false positive entry is on the list, 
then a DROP'ed connection is just a temporary error. The sender does receive 
a message like "tried to often, receiver unreachable" after several days. 
When BLOCK'ing as before, He get's a 5xx error immediately, that tells him 
what is wrong (as I give some hint in the custom block message).

I would be glad to DROP connections from some really obvious DNSBLs but 
dropping all of them is not good for me.

regards, Bernd
