Hi,

I put the IP 1.46.135.207 into deny list. However, this IP can still access my Wordpress site of the server.

How can this possibly occur?

Are there any solutions to block it?

We have CSF installed on our server and it seems to block mail coming from our billing system. I have configured it to allow the SMTP PHP mail to go through. It starts working for a few days then starts blocking again. I have to reboot the CSF services for it to start working again then it does the same thing a few days later.

Is there any insight as to why this is happening?

A customer is not configuring properly her email account. I am still trying to understand what she is doing wrong, because I can configure myself her email account in my laptop without no issues.

Since she is doing something wrong, CSF reports login errors and tries to...

I would love to be able to use an allow list to retrieve the CloudFlare IP addresses regularly at these URLs, then apply my own advanced allowed rules to these IP addresses.

Similar to the feature of the Block Lists text file, where one can configure a URL to retrieve IP addresses from to be downloaded regularly and blocked in the firewall, is there currently a feature for an allow list? If...

Whats the proper configuration when using postfix on a server instead of sendmail when it comes to notifications? Seems it wants a sendmail binary path.

I understand the need to send resource-depleted services to the server administrator. These are important.

Yet, everywhere I look on how to ignore them or stop innocent alerts from being sent, not in any of them I can find understandable explanation on when to use the cmd vs. pcmd entry in the csf.pingore file.

Can someone please explain the different?

I am receiving boatloads of alert emails...
