Are there problems I'm missing? I would add "-w whiteclnt" to the invocation of dccproc to specify a white/blacklist. If qmail knows the IP address and can put it into the command line, I would also use "-a whatever". Otherwise, if qmail has added a Received line by that point and it is in a standard sendmail style that dccproc can recognize, I would use -R. If qmail has not added the received line, I would probably not use -R, because the Received lines of systems other than your own often cannot be trusted. I know nothing about how qmail works, except for its evident habit in some configurations of not adding Message-ID lines to mail it relays and originating bounces without Message-ID lines. A DCC client blacklist entry of "many message-id <>" is quite effective for me, because a lot of bulk mail lacks Message-ID lines. I've received bounces that appear to have come from qmail systems and that lacked Message-IDs. Other people who tried that blacklisting DCC white list entry found it tagged mail from some mailing lists. Judging from headers, my wild guess is that they somehow use both `sendmail -bs` and qmail.
