In my cpanel server, I have installed CSF as a plugin. Once all the configuration is done, i give csf -r command to reload. but the below Warning message is showing. Since its a Warning I dont give much importance, but I need to resolve it.Tags: WHM cPanel CSF (ConfigServer Security & Firewall) – LFD (Login Failure Daemon)
SMTP block will be given as default in CSF so when you enable in cPanel, it will be conflicted. So go to the mentioned path WHM > Tweak Settings > Restrict outgoing SMTP To Root, Exim, And Mailman (FKA SMTP Tweak) and change it to OFF
After that give csf -r command. It will not show the Warning.
