Well, my point is dccifd really works for greylisting in production,
something that Vernon was not shure of. We process several millions of
incoming messages a day using it.

As for postfix integration, we hook dccif() call into data_cmd() in
src/smtpd/smtpd.c . This approach not perfect as it needs an additional
queue file and one cannot insert X-DCC headers here - message is already
passed to cleanup daemon. If there is enough interest i may clean up uor
code and release it, however it is quite limited - we don't do dcc
rejects, only greylist embargo.

There is also another pre-greylisting dcc/postfix integration patch at
, you may want to look at that.
