Tigase server 5.1.0 or later offers support for Advanced Message Processing, called AMP or XEP-0079.
It is enabled by default but there are several configuration options that you may tweak.
Configuration of AMP is not very complex, but as it is implemented as a component in the Tigase server it does needs a few settings to get it right.
Here is a first, brief overview of the AMP configuration and later detailed explanation of each parameter.
