SpamAssassin Configuration Adjustments Not Affecting Filtering

Hi everyone,
I've made some adjustments to SpamAssassin's /etc/mail/spamassassin/local.cf to try to increase the weight given to DCC and Razor2. However, when I look at spam that comes through, the weights do not seem to have budged (as they are listed in the suspicious e-mail's headers). I've restarted exim (and thus spamd), but that doesn't seem to help.

Any ideas?

Thanks,
Tim
