Spam is unsolicited bulk email, but DCC only detects "bulk."
So one needs to combine DCC with a mechanism for detecting "solicited."
Whether a given copy of a bulk mailing is solicited depends on the
individual target, so the best way to detect "solicited" is with
per-user, individual whitelists.  Something like the cgi scripts
in the DCC source can be used (and are at some installations) to 
let users handle their own whitelists.  Those scripts are demonstrated
at http://cgi-demo:cgi-demo@www.rhyolite.com/dcc-demo-cgi-bin/
Many other DCC installations use a scoring system such as SpamAssassin.
