logging whitelisted IPs

[Tomas Macek]

I'd like to have an whitelist based on hash:<file> table, for example this 
http://www.howtoforge.com/how-to-whitelist-hosts-ip-addresses-in-postfix - 
it's simple.

When I have a line
        1.2.3.4 REJECT You were blacklisted

it's logged including reason of rejecting (of course).

But when I have a line

        1.2.3.4 OK You were whitelisted

it's not logged at all and I don't know why the IP was able to sent a mail 
through the mailserver and why. Is there any possibility to achieve that?
