E-Mail / [Error 450] Can't send emails from a specific domain
« on: January 07, 2021, 06:06:15 AM »

A client of mine which her site is hosted on my CWP Pro server, can't seem to be able to send emails.
When trying to send from her Gmail with all correct SMTP settings, she's getting an error after some time from google saying the email could not be delivered to the recipient.
To troubleshoot the issue, I've tried sending an email from her account with RoundCube, but with this one it's not even being sent. I immediately get the following error:

SMTP Error (450): Failed to add recipient ... (4.7.1 <...>: Recipient address rejected: Access denied).

Link to screenshot:

But the email I'm trying to send to is my own, and I know for a fact it's working. I've tried sending to other emails with other domains, all give the same error.

Any idea what's going on?

Oh, I've already checked - her domain is not blacklisted by any means. So I'm quite lost to what could be the issue.

CentOS 7 Problems / Too many system updates
« on: November 25, 2020, 03:31:45 AM »
Hi there,

My CWP Pro GUI shows I have 176 available yum/rpm updates.
Usually this was moving around 1-10 max and I was updating my system with (almost) no fear.
About 2 weeks ago I all of a sudden got these 176 updates notification, and I'm really afraid to let it update so many updates.

What do you say? I'm running CentOS 7 by the way...

Updates / cluebringer?

Today I saw on the daily cronjob email the following.
Please advise what that is.

CentOS-WebPanel Bugs / Backups for removed users are kept
« on: September 22, 2020, 09:33:04 AM »
Hi There,

I've just noticed that backups for users that were removed already a few months ago, are still showing under the daily, weekly and monthly folders under backup folder.
Why isn't the system clearing these when the user is being deleted?
Is it safe to delete those manually now?

Not getting alerts doesn't say SSH is not being attacked constantly.
On the contrary, I want to be aware of such, but am wondering if there's anything i can do to stop it.

Be sure to use IPset and maintain a fairly large blocklist - I usually have 800, in addition to csf.blocklists, country blocklists and AWS blocked.
I've installed and configured IPset 48 hours ago and still getting lots of notifications. :(

Apache / Re: Error 520 Web server is returning an unknown error

Happened to me too. I've opened a thread here but eventually found the fix by myself. Maybe it's the same with your.

MySQL / Re: Why do I have 6 users for each DB?
« on: September 10, 2020, 06:53:09 AM »
Yes. You can use the users other than [localhost] since others are not needed.

This happens when you import cPanel account to CWP. I have sent the ticket to CWP support for the same issue and hoping a response from them.
Did you get a reply?

This will be very soon in the user panel and admin!
How soon is this very soon from February?

Ok, I've fixed it.[/size]It seems I've installed HTTP/2 both in Nginx and Apache. Removing it from Apache - fixed the issue.Actually, I've emptied the http2.conf file and recompiled Apache.[/color]

Varnish 6.4 is already incorporated in centos 8:
But CWP is still using CentOS7, right?

By official CSF GUI, do you refer to this screenshot?

As to blocking it completely - then I wouldn't be able to login to FTP and SSH with my keys...
As to IPset, never heard of it. I'll check.

For the last 2 weeks, someone (apparently some bot automatically running) is trying to log into SSH with different ports, IPs and usernames.
Apart from the annoying emails every 5 minutes telling me an IP was blocked - is there anything I can do to block this guy?
I've reduced the wrong tries to get blocked to 2 and the period increased to 120 minutes.

Anything else you might advise?
