spam-filter v3.0.3 follows upstream's 1.0 server: it renames the AI classifier's LLM_* tags to AI_* and the lookups' refresh setting to refreshInterval, neither of which this server uses. Taken in, it would score the classifier's verdicts at 0 on new installs and quietly reset every lookup's refresh interval. The rules stay on v3.0.2 and are maintained here from now on, versioned 3.0.2-inbuxa.N. The first change adds scores for the DKIM2 result tags the server already emits, with v3.0.3's values: DKIM2_ALLOW -0.2, DKIM2_REJECT 1.0, the others 0. spam-rules-watch only watched spam-filter, so it goes too.
