CSF is blocking all external email (gmail, hotmail, yahoo, etc). I have seen a few discussions on this topic here but nothing specifically fixes the problem.
CSF v14.18
WHM/cPanel 110.5
External emails work fine when CSF is off. I saw one thread that mentions something about WHM v110.5 and sshd and smtp settings but the solution is not specific enough to implement.
Hello,
I am using whm with csf, csx, and i have zerotier on the server (www.zerotier.com).
From time to time, zerotier goes offline and cannot connect to its network.
To fix this, i stop csf, restart zerotier, it turns on, i turn back on csf. It works for a while.
I have two related questions if you could answer, I would be very grateful;
1) I am using Mod security as well as CSV on my Apache Centos server.

This is definitely a critical bug and needs to be addressed
Kindly treat this as critical to be addressed on urgent priority
When I insert that into the csf to block, it blocks it no problem but also doesn't allow me to send emails to subsribers in that range - keep getting DNS request timeout.
So is there a way to block an ASN inbound from the scanners and such, but allow outbound...
I've got the X country in CC_ALLOW and want to bypass all checks and more specific the imap/pop3.
At the time being if someone fail to login for a few times it blocks the IP. I want not to blocked/checked at all from this X country.
Is that possible?
The CC_DENY_PORTS setting should only block access to TCP and UDP IN, but it applies to OUT as well.
In the description in the conf file, it informs TCP_IN and induces to think that it will be only for IN(put)
# This option uses the same format as TCP_IN/UDP_IN. The ports listed should
