I didn't think it was possible, but with the latest Zimbra update, spam filtering has gotten even worse.
I would like to override some of the scores for SpamAssassin, but for some reason, my override is not taking effect.
For example, I want to give URIBL_DBL_SPAM more weight. The score is defined in 50_scores.cf. I first tried local.cf, but that didn't do anything, so then I added it to 72_scores.cf, which I assume gets parsed AFTER 50_scores.cf, but it is still not being overridden. Can someone tell me the proper place to override scores?
