Vernon replied off-list so I wanted to bring the relevant portion back
to the list:

"My general suggestion is that SA+DCC clients that don't use whitelists
for bulk mail (I still say whitelists are required) should use a DCC
score that is not large enough to tell SA to mark a message "spam"
purely from the DCC result, but large enough to push other signs of spam
over the threshold. vjs"

So I think DCC users should consider moving DCC to an __ test and
identify things like DNSBLs with whitelist entries and other tests that
can use DCC to meta more effective classification rules.

Anyone has any thoughts on rules to submit, let me know!

Regards,
KAM
