For starters, everyone behind a common NAT gateway will be authorized to send mail as the client that initiated the POP before SMTP, as it just means "IP x.x.x.x has sucessfully authorized, they may send mail now" and all clients behind the NAT will appear with the same IP. Potentially, this might mean 1000s of completely random, unreleated users can use ...

Update the cron job to mail you when stuff gets upgraded. You are probably better off grepping through the output for things that require a reboot (like the kernel), otherwise you're pretty much guaranteed an email every day: Linux distributions are constantly pushing new software into production. A few general notes cPanel is not a person, nor does it ...

You should configure your web server to not only use the certificate you were issued but to also provide the CA's intermediate certificates. I suspect that you have not properly configured it to serve the intermediate certificates provided by your CA. Failure to do so will lead to inconsistent behavior. For modern Apache httpd versions (>=2.4.8) you would ...

I suppose your are on worker-mpm mode. At first you can increase the default values like this, considering your server / trafic : ServerLimit 2000 ListenBacklog 500 StartServers 100 MinSpareServers 50 MaxSpareServers 100 MaxClients 2000 The default configuration is more for testing environment. You server limit is very low for ...

Currently your email is going to mx0.123-reg.co.uk and mx1.123-reg.co.uk as indicated by the MX records in your DNS zone. If you want your email to go to the host named mail.yourdomain.com (as represented by the A record in your DNS zone) then you need to change the MX record(s) to reflect that. The MX record is used to designate the host or hosts that ...

The Received header that has a numerical HELO is not the one with the HELO provided by Exim. Exim is sending charlotte.studiomod.us. The HELO that is being complained about is the one provided by the program you are using to send your mail: roundcube. Selecting only Received headers from your mail makes this easier to see: the first line is internal to ...

I know this is an old topic but for future readers, check /usr/local/cpanel/logs/login_log That log shows a list of failed login attempts and deferred login attempts.

Ok, what you've got there seems very odd. You setup should look something like this: Hostname Setup: Hostname: mydomain.com Name Server 1: ns1.mydomain.com Name Server 2: ns2.mydomain.com Name Server 3: ns3.mydomain.com Name Server 4: ns4.mydomain.com Name Server 5: ns5.mydomain.com Name Server 6: ns6.mydomain.com I assume you are using a commerical DNS ...

Firstly, check the syntax of the apache file with the following command: /usr/local/apache/bin/httpd -t You can either fix these manually, or preferably, rebuild your configuration using cPanel's tool. Using cpanel's method, backup your httpd.conf, and run /scripts/rebuildhttpconf Then check the syntax again and try your change if that resolved the issue. ...

Every cPanel server should have this length limit enforced regardless of version, since MySQL itself has a limit of 16 characters for a username. Thus, when you create a MySQL user for the cPanel user, you end up with 7 characters to spare: unixuser_1234567 Citation for MySQL 16 character max: http://dev.mysql.com/doc/refman/4.1/en/user-names.html

You should do this from the WHM interface from the basic setup section - I haven't used WMH in almost 1 year now and don't have access to one to check, but the documentation indicates that it is in Home >> Server Configuration >> Basic cPanel & WHM Setup More information can be found at ...

First, you should be sure that you can resolve www.example.com. When you ping www.example.com, does it resolve the same IP address as example.com? If the resolve for both are to the same address, the issue is more than likely host header related. If you are running IIS, open IIS Manager and expand your sites. Right click the site for example.com and ...
