When you understood that many email are not delivered in your inbox which are sent from (Hotmail,Google or custom server) first of all you must check logs whats happening, if dns is configured properly and you see “Could not complete sender verify callout” in your logs which you can check in whm “Email”->” Mail Delivery Reports ” then this is because of Sender Verification Callouts
Use callouts to verify the existence of email senders. Exim will connect to the mail exchanger for a given address to verify it exists before accepting mail from it.
we can fix it very fast just go to “Exim Configuration Manager” in WHM and search for “Sender Verification Callout” check off which by the way is default, click save and test your mails.
By default Cpanel comes with apache only, if you need to install Nginx,Varnish to make faster service you can use several plugins, I will start with free one and then tell about shareware.
Plugin comes with already configured Nginx and Varnish, to install and use terminal
tar -zxf apachebooster.tar.gz
bash install.sh or sh install.sh
after installation you will see apachebooster in WHM plugins
You can configure Varnish and Nginx from here, and also purge varnish cache if needed. I think this plugin have have all what is needed but if your searching for more you can buy Cpanel plugin from Unixy, I think they have same functions but anyway it up to you which one to choose.
There was a problem creating the parked domain. Show Details
Error from park wrapper: Using nameservers with the following IPs: xxx.xxx.xxx.xxx,xxx.xxx.xxx.xxx Sorry, the domain is already pointed to an IP address that does not appear to use DNS servers associated with this server. Please transfer the domain to this servers nameservers or have your administrator add one of its nameservers to /etc/ips.remotedns and make the proper A entries on that remote nameserver.
If you have access to WHM you must make this change –
