The DCC detects bulk mail.  Whether a given copy of a bulk message is
spam can only be decided locally by or on behalf of the recipient that
copy of the message.

You need to put add the Dilbert newsletter to your site whitelist
or the per-user whitelists of subscribers.

The cgi-bin directory in the DCC tarball includes proof-of-concept
CGI scripts that let individual end-users manipulate their per-user

I frequently use `dccproc -QC` 
`dccproc -El logdir` might also be useful.

However, the default and almost universal configuration of DCC servers
is to not count any except the Body, Fuz1, and Fuz2 checksums of message
bodies.  As a result, there are no flooded checksums except body checksums.
See `dccd -K` to change that for your own DCC servers.
