    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?

    IPv6 kommt. Okay, seit 10 Jahren. Aber nun hat IPv6 ja wirklich den Einzug in die Rechenzentren genommen, der Produktivbetrieb hat begonnen.

    Was sich durch IPv6 bei Mailservern und Anti-Spam-Mechanismen ändert, was zu beachten und was total egal ist, ist Thema dieses Vortrages.

    Und, übrigens: Auch wer nur IPv4 macht, wird an IPv6-Probleme nicht ganz vorbeikommen.

    Verschlüsselung ist aktueller den je. Dennoch scheuen sich Administratoren davor oder begegnen dem Thema zumindest mit Respekt. Zurecht, kann man doch Einiges falsch machen und sich damit in trügerischer Sicherheit wiegen. Der Vortrag beleuchtet Planung, Einrichtung und Betrieb von TLS nicht nur bei Mailservern.

    This year's Postfix release introduces support for a new protocol "DANE" that uses secure DNS to authenticate a mail server's TLS server certificate. This avoids a major weakness in the traditional PKI (public-key infrastructure) where literally hundreds of certificate authorities (CAs) and registratoin authrities (RAs) world-wide can create a certificate in anyone's name. Some of these make mistakes or get hacked. Some are owned by their government, or have strong relations with their government. With secure DNS you only have to trust the people who control the email receiver's Internet domain and those who control its parent domains. You don't have to trust hundreds of CAs and RAs world-wide. There is also new support for a database called LMDB that aims to give better performance and reliability, and that comes with a less restrictive license than the latest versions of Berkeley DB. This development required a lot of persistence, taking five iterations. I think that the result is worth the effort. Finally, the new release continues to make Postfix configurations easier to manage with other programs. A Postfix system does not live in a universe by itself: it needs to work as a building block in a larger system.
