I never saw any issues with sending and BlackIce unless the user wasn't authenticated or wasn't from a safe IP. Even so the automatic blacklisting is temporary. We installed BlackIce because of the huge problem we've been having with dictionary attacks. Unfortunately in our experience BlackIce does not act against these attacks until the attack is mostly complete at which time time it does temporarily blacklist the offending ip address. This apparently has to do with how it detects the maximum errors along with how Imail reports them. So it is still not unusual for us to have attacks that attempt more than one hundred recipients. Now this is an improvement because unprotected we've seen many instances where the attacks try thousands of recipients. However we started having 0x0000007F Errors causing the server to reboot. In our case the error was "0x00000008 Double Fault." I suspected BlackIce and turned it off and the errors have ceased.
