Basic concepts of plumbing an Amavis content filter with a Postfix mailer. Comparison with a SpamAssassin spamc/spamd setup. Keystones of customized settings: policy banks and per-recipient settings. Noting some of the newer features of SpamAssassin 3.4.0 and Amavis. Understanding the ZeroMQ-based infrastructure for monitoring amavisd health and providing measurements over SNMP. How is a Redis database server used for "pen pals" and IP reputation lookups, for feeding mail events to log analyzers, and as a SpamAssassin's Bayes storage. Getting insight into site's mail traffic by putting the new Amavis JSON structured reporting to good use: feeding it through Logstash to ElasticSearch and Kibana. Can it all run in an IPv6-only environment?
