While I work primarily with Cpanel CloudLinux servers, I am also beginning to work with Webmin and DirectAdmin Servers.
I am aware that you can install the CSF/LFD software in DirectAdmin servers.
But what exactly is this Messanger service?
Is it documented here within DirectAdmin documentation: https://docs.directadmin.com/operation- ... f/csf.html ?
