What about the idea of basing the log file name on the checksum?

Yes, users are going to want to whitelist the addresses to aviod delays.
Believe me, we hear about it when mail is delayed for any reason and
need to provide an option to avoid the greylisting delay.  I would put
messages that passed in a view from the rejected one.

Some people want to know exactly what message are being rejected.  If we
don't log the greyed message, especially legit mail from broken mailers,
people will be unhappy.
