How would you do the wiring? Back in time when the dccifd didn't exist
I made a custom dlopen() dynamic module api for Postfix, and plugged the 
DCC into smtpd for the checksum calculations. I'm still running it, I 
have to maintain it, I do not like this solution at all, but fortunately 
both projects have evolved a lot in this field :-)

Perhaps a better solution would make use of dccifd on the DCC side, and
SMTP/LMTP on the other, for both real time and content_filter message
inspection. For DCC greylisting, Postfix's policy delegation protocol
seems okay.

I definitely would be pleased, although I cannot guarantee fast response 
times...
