If you're doing those tests in maildrop, you'll see a backup in your
queue. If you're doing the tests via pythonfilter, then the mail will
back up in someone else's queue. If you're not doing the tests at all,
you get a lot of spam in your mailboxes. Take your pick. :)

Make sure that these lines are not commented in
/etc/mail/spamassassin/v310.pre:
loadplugin Mail::SpamAssassin::Plugin::DCC
loadplugin Mail::SpamAssassin::Plugin::Pyzor
loadplugin Mail::SpamAssassin::Plugin::Razor2
Each of the three requires a small amount of configuration:
test -d /etc/razor -a ! -f /etc/razor/razor-agent.conf && {
razor-admin -home=/etc/razor -register
razor-admin -home=/etc/razor -create
razor-admin -home=/etc/razor -discover
}
test -d /etc/pyzor -a ! -f /etc/pyzor/servers && \
pyzor --homedir /etc/pyzor discover
DCC needs you to edit /etc/dcc/dcc_conf and set:
DCCIFD_ENABLE=on
You should also edit /etc/dcc/whiteclnt and add "submit" lines for your
private or client networks.
And it needs to run on startup. I use:
ln -s ../../../usr/libexec/dcc/rcDCC /etc/init.d/DCC
chkconfig --add DCC
