A basic dcc install (without running your own server) checks the
'public' servers that it's configured to check to generate the DCC_CHECK
score that your local SA uses. In this config, you are contributing just
the same as if you ran your own server, since the dcc servers you are
hitting will include your spam reports with their own.

If you get a lot of spam (as we do), you'll eventually get an email from
Vernon @ ryholite software asking you to stop hammering the public
servers and run your own! ;-).

You run the server 'dccd', and set it up to peer with several other dccd
servers. They exchange data regularly, so that you have a copy of the
global database. It's a bit odd in it's filenames/filestructure, but
it's free and it works well, is well supported and seems to be actively

One note of caution. It's a memory hog(currently 264012 KB), but stable.

I've not used dccifd before.
