DCC effectiveness has dropped in recent months. Perhaps that is due to more triggering of that MIME bug. Or perhaps not. Clients of a DCC server that does not receive "floods" of reports of bulk mail from the rest of the global DCC network are likely to much less effective. I don't recall that ripco.com is running a DCC server connected to the global network. In my mail logs there is some corresondence with you about DCC servers, opus.com, Barracuda, and the possible assignment of DCC server-IDs, but I think nothing came of it. What DCC server are you using that is connected to the global network? If your DCC server is not connected and you now have enough traffic to justify a local DCC server, please contact me privately. Note that the free license for the current DCC source does not cover installations of DCC servers not connected to the global network. To do that, you need to buy a commercial license. "False positives" are different story and speak more to a misuse or misunderstanding of distributed checksum clearinghouses. In a sense, albeit uninteresting, there is no such thing as a DCC false positive. If the DCC network says that a mail message is bulk, then you can be confident that at least one substantially identical copy of the message has been reported before. There two common classes of claimed DCC false positives. One consists of nearly empty messages consisting of few or no words and some free mail provider advertising, shyster confidentiality noise, or similar popular noise. The other class consists of legitimate bulk mail that has been detected as such, including messages from legitimate mailing lists that has been reported to a DCC server with a target count of "MANY." The only solution for both classes is to whitelist such legitimate bulk mail in the system-wide /var/dcc/whiteclnt file or appropriate per-user whiteclnt files.
