Whitelist entries missing from server database

I have observed an inconsistency with DCC server whitelisting.  Of some 750
'ok From' entries in our whitelist, only 600 appear to make it into the
server database.

As a result of this discovery, I have further observed the following ratio
of whitelisted checksums apparently missing from our server database:
      From       20%
	env_From    5%
	Fuz1        9%
	Fuz2        7%

A section of our whitelist appears at the end of this message, along with
the relevant portion of dblist output.  The first 'virginblue' entry has
made it into the database, while the second has not.

I can confirm that the client whitelist appears to contain all entries, as
per the examples below.  I realise the "easy" answer is to use client
whitelisting, however we do rely on server whitelisting for some portion of
our client base at this time.


Of note, the following 3 examples.

No client whitelist - server responds 'OK'.
From: "virginblue.com.au" <vmail@virginblue.com.au>
	From: ccdcfd8e b66f2c68 f5cc66f3 608627fb      ok

No client whitelist - server responds '0'.
From: virginblue.com.au <vmail@virginblue.com.au>
	From: 80d2b356 43da127c b5095541 9ec3fc54       0

Using server whitelist as a client whitelist - client responds 'OK'.
From: virginblue.com.au <vmail@virginblue.com.au>
	From: 80d2b356 43da127c b5095541 9ec3fc54            ok
