Given that what are people's thoughts on using DCC in SA?

DCC gives a high hit rate on SPAM here, but also contributes highly to
false positives.  Since setting up DCC I seem to have lots of list
emails reported as false positives, and spend a fair amount of time
checking and tweaking whitelisting settings for these.  And in most
cases a combination of DCC and a highish Bayes score is enough to tip
these over.  I know I could adjust the DCC score, but was wondering what
other people do?

The thing with DCC is that it combines checking and reporting, which is why it is an indicator of bulkiness and not spamminess, as you say. To get around that you should whitelist all mailing lists so that mailing list mail isn't checked against DCC, both to avoid false positives yourself and to help others avoid false positives.

So basically you're right and I haven't added anything. What I can add is that I don't use DCC myself, for precisely the aforementioned reason, i.e. that it requires to much fiddling with mailing lists.


Thanks for your comments. This confirms where I had reached in my thinking about DCC.
