Hello.
I'm using cPanel & WHM v102.0.8 (STANDARD) and CSF Firewall v14.16.
Today I changed some settings: SMTP_ALLOWUSER (added another user) and also added some ports to TCP_OUT list. Then I restarted the firewall and tested the new rules. Everything worked fine.
Some minutes later, the connections stopped working. Reviewed the configuration again and found that the changes I made were lost. That problem happens everytime I try to set the parameters.
What could cause this strange issue?
Any suggestion will be appreciated.
