For those reading at home, DCC is a hash sharing system used in spam 
filtering to recognise bulk email: https://www.rhyolite.com/dcc/

We were using dcc until a debian upgrade meant zanchey had to restore a 
default spamassassin config. I haven't bothered looking at it since 
because the spam filtering was working well enough for my needs.

The DCC module is loaded with a line in /etc/spamassassin/v310.pre, but 
then the local.cf config isn't telling spamassassin to filter traffic 
using said module.

If anyone is keen, the old config on mooneye is in 
/etc/spamassassin/local.cf.dpkg-old and would need porting to 

It would be good if we could re-enable pyzor and razor at the same time
(more spam reporting and detection services).

If a non-wheel member wants to take a look at this, poke me and we'll see 
what we can do.
