Install

Install the components in the order listed below - the server module and the Administrator Panel both need Java, and Postfix is configured last, once the milter is running.

• Java - install and verify Java 21 or newer on Linux, Windows and macOS, and configure JAVA_HOME.
• Server module - download the server module package and install it on Ubuntu, CentOS/RHEL or Debian.
• Administrator panel - download and launch the desktop application used to configure the server on Windows, Linux and macOS.
• Postfix configuration - register the milter in Postfix so that incoming and locally submitted messages are processed.
