When it comes to connectivity, Tigase XMPP Server sported Hardened Mode that adjusted networking security settings (supported protocols, cipher suites and keys' length where applicable). We decided
include 3-level configuration option for Hardened Mode (roughly following Mozilla’s SSL Configuration Generator): relaxed, secure (default) and strict and to further eliminate cipher suites that are currently considered insecure.
We also enabled by default our anti-spam plugin and because we like all-things-extensible we created a guide how to create your own pluggable filters for anti-spam-plugin.
