Disabling CSF makes them work as normal. Obviously I don't want to run with CSF disabled.

I've added various ports in, reset it, reinstalled it but nothing works other than fully disabling it.

The message I get from mail-tester.com is Your SMTP or web host is probably blocking your emails .

If this a know issue and is there a fix?

Thanks

As of about a week ago CSF appears to be timing out processing of queued emails. If the message is sent manually using WHM > Mail Queue it times out.
Nothing more specific than connection timeout is reported.
At the same time we started getting random calls from clients, their website wouldn't load for them, mail app can't connect etc.
We have flushed everything, restarted and...

Having the instant IP block is an awesome feature and we use it frequently for repeat offenders. But these days so many spammers are sending from multiple IPs from a single CIDR 24 block. It would be so cool to have two options to click to block. One like the current single IP block, and a second one right next to it that blocks the entire range, ie NN.NN.NN.0/24. We do this manually at times but...

Hi there

A new server with Cloudlinux installed, Installed CFS, but all messages are logged to the console, making the console unusable.

I have no idea what setting needs to be done for this to stop. Any help is appreciated, as I am sure I am not the only one. This was presented before here: (but no fix was provided)

screen looks like this:

Instructions I think how to block tor in /etc/csf/csf.blocklists by uncommenting this line (remove the #):
#TOR|86400|0|
and in /etc/csf/csf.conf make sure URLGET is set to use LWP then restart the firewall

We leave the ip=1.2.3.4 and don't change it to our server ip address?

I've bunch of ips / networks added to csf.deny

csf.deny
1.1.0.0/19 # do not delete

However i want to allow 1.1.1.1 on port 80 and 443 with csf.allow

csf.allow
tcp|in|d=80|s=1.1.1.1
tcp|in|d=443|s=1.1.1.1

or

csf.allow
1.1.1.1

Allow rules above is not working.

- If i add IP adress to both csf.allow and csf.ignore it works but opens all ports which i don't want to
- Adding...

Does this error indicate a Zone file error? If so, what is the best way to correct it?

Dear all,

I am using block_all_temp profile to temporarily block the IPs attempting a brute force attack. using this profile, it only allows me to block the IPs for 1 hour aftr this the IPs get unblocked. i want to customize this time to 5 min for example. so that, any IP trying brute force attack will be blocked for 5 minutes only. help will be grateful.

Hi there,

With the High Load template for instance, there are set variables which don't seem to be documented.

This includes , , , , and however there doesn't seem to be a way to tweak them. For instance, we'd like to amend how ps is invoked (and likely include a 2nd copy of it, sorted differently), include iostat/sar reports and others.

How does one go about amending what the above variables...

Hello,

Having too many data in /etc/csf/csf.deny makes it impossible to edit the file in a web-interface of Directadmin.
It is a built-in limit in DirectAdmin when a loading variable 'POST' is limited to hard-coded 125749 bytes. Whenever a 'POST' request of a bigger size arrives it gets rejected by DirectAdmin and no changes are actually saved.

In Directadmin logs one can see a line of the...

Hi,

I've noticed that the cPanel disk usage emails sent to hosted clients were all marked as low spam.

The emails were sent from cpanel@local-domain-name with a client IP of 127.0.0.1 and tripped the KAM_MAILBOX2 rule with a score of 6.25.

The KAM_MAILBOX2 rule relates to Mailbox Quota Phishing Scams.

How do I stop internal cpanel emails from triggering this rule while keeping the score as...
