The idea is that > might make it easy (or easier) to wire dccifd into postfix. 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. > If so, does someone have a postfix installation that could test > such a beast? I definitely would be pleased, although I cannot guarantee fast response times... Leandro.
