Since the dccd database can't really store anything except 24 bit
values with the keys that are checksums, I don't see an alternative.

There are some optimizations that could be made.  You could use
fgrep.  Only files with mtimes within the greylist "wait" time window
(default 5 days) would need to be checked.

I realized today that one would have to look at the second of the
greylist checksums at the end of log files to related all of the log files
for an embargoed message.

Would users likely to be concerned really care about messages that
had passed the embargo. 
Would they understand more information about those that hadn't or just
become even more concerned?
