Ah.  Your first reply sounded like you were telling my
the behavior I wanted was already there.

The following sequence could happen:

 	1) message is reported as spam to DCC server #1
        2) client switches to DCC server #2
	3) message is queried against DCC server #2,
	   and accepted for all recipients.
        4) checksum is flooded from server #1 to server #2

Although it's not the end of the world, it is unreliable,
and not a very clean solution (you waste a query to the
DCC server just to consult the dccifd whiteclnt and
userdirs).  If dccifd treated bulk mail the same whether
it gets the "bulkiness" from the MTA or the DCC server,
I could cleanly and reliably do this with one query.

Would this behavior be appropriate with a different option?
That is, don't change the behavior of DCCIF_OPT_ISSPAM,
but add a DCCIF_OPT_PROBABLE_SPAM which tells dccifd that
the MTA thinks the message is spam, but doesn't override
whitelisting.  Does this sound like a good idea?
