Troubles with email deliverability? Learn how to diagnose and fix mail-related DNS issues using WHM’s Email Deliverability interface.
Parked domains let you point multiple domains to your primary website without separate hosting. This UnderHost tutorial reveals professional techniques for managing them efficiently in cPanel.
If you manage the server, turn on backups in WHM > Backup > Backup Configuration: pick a schedule, a retention period and an off-site destination, and cPanel runs them automatically. If you only have a cPanel account, schedule a full backup with a cron job that calls cPanel's Backup API and sends the file to another server over SSH with a key. Never put passwords in cron jobs or scripts, and test a restore regularly.
An addon domain is a second, separate website on the same cPanel account, with its own folder, email addresses and SSL certificate. In current cPanel, open Domains > Domains, click Create A New Domain, enter the domain, untick Share document root, choose a folder such as example.net, and submit. Point the domain's DNS to your hosting first.
A simple tweak to your system’s hosts file can allow immediate access to a website without waiting for DNS propagation.
DNS resolution failures can cause serious connectivity issues on your server. If your system can’t resolve domain names, it could be due to a misconfigured /etc/resolv.conf or missing Perl modules. This guide walks you through troubleshooting steps to restore DNS functionality efficiently.
