Hello.

I am using "ConfigServer Security & Firewall" and I am trying to configure sending mail and security issues.

When sending mail using non-ssl my sending client IPs end-up blacklisted at my "ConfigServer Security & Firewall".
It happens every time their internet provider changes their IP address.

Is there a way to exclude a domain from blacklisting at my "ConfigServer Security & Firewall"?
I am tired of whitelisting their IP addresses every 2-3 days.

Good point.
Thank you for your reply.

I am just curious:
I am using cPanel with my web server with more than 40 domains (web and email server).
I think that security of my server is just fine.
Is there a need of using "ConfigServer Security & Firewall" at all?

I'm not sure that any of us know enough about your specific server setup to tell you whether you need to use it or not. In general, I don't know of anyone that would recommend not using some sort of firewall, whether it's CSF/APF or a hardware-based one. As far as CSF is concerned, I'm not entirely a fan of the product on busier servers, but for one of your size it's better than nothing.
