Leave a reply

cPanel v66 introduced a new option – Number of emails a domain may send per day before the system sends a notification. With this option, the system will send you a message when a domain exceeds the specified number of daily emails.

cPanel Note: The system counts outbound mail from subdomains and addon domains separately from their parent domain.

By default the option is set to Unlimited. You can set any value you want – like 10, 100 etc.

  2. Go to Server Configuration >> Tweak Settings
  3. From the top menu click on the Mail tab
  4. Look for the option Number of emails a domain may send per day before the system sends a notification
  5. Choose Unlimited or enter a value (10,100 etc)
  6. Scroll down the page and click the Save button
  7. You will see the confirmation message:

    Your changes have been saved.

    Restarting cPanel daemons…done.

    Updating your system to reflect any changes…
    Updating “Number of emails a domain may send per day before the system sends a notification.” from “10” to “100”.
    “Number of emails a domain may send per day before the system sends a notification.” was updated.
    Done.

When the condition is triggered, you will receive an message stating that The domain demo123.com on account demo123 exceeded the maximum number of emails per hour. The domain violated its domain-level limit, which is currently 100.

How to check if a domain is on the server

Leave a reply

You have a lot of domains and you want to quickly check if a domain exists on the server. Just run the shell command: grep yourdomain /etc/userdomains

root@web [~]# grep demo.plothost.com /etc/userdomains
demo.plothost.com: plothost
root@web [~]#

In this case, the domain “demo.plothost.com” exists and it belongs to user “plothost”.

You may also want to know if the domain resolves to your server/IP. Use:

root@web [~]# dig demo.plothost.com

; <<>> DiG 9.9.0-RedHat-9.9.0-38.el7_3.2 <<>> demo.plothost.com
;; global options: +cmd

How to restart a service via WHM interface

Leave a reply

cPanel/WHM offers a nice graphic interface to restart important services like Apache, FTP, MySQL etc.
First, you should login to WHM as root. Go to Restart Services menu like in the image bellow.
restart services

From here just select the service you want to restart and click the “Yes” button like in the following image .
restart services 2
The example is for the pure-ftpd service, but the interface is the same for all other services.

After the service is successfully restarted you will get a message like :

Waiting for ftpserver to restart………finished.
pure-ftpd (pure-ftpd (PRIV)) running as root with PID 4062 (process table check method)
pure-authd (/usr/sbin/pure-authd -s /var/run/ftpd.sock -r /usr/local/cpanel/bin/pureauth) running as root with PID 4050 (pidfile check method)
ftpserver started ok

The exact image is
restart services 3
